Berserker´s true Identity is Sir Lamorak of Wales, Proud Knight of the Round Table, Daughter to King Pellinore and Lover to the Witch Morgan Le Fae… But in this summon she has been brought as an Alter that is nothing more than a shameless Beast who lacks morals that wants to see the entire world burn down   Sir Lamorak was one of three knights most noted for their deeds of prowess, and at an early age she received a degree for jousting, at which she excelled. On several different occasions, Lamorak fought over thirty knights by herself, killing or besting them all.    During her early life Sir Lamorak had various misadventures alongside Sir Tristan, sometimes appearing as enemies to one another, other times having to work as allies to deal with a bigger threat but ultimately they constant adventures made them become great friends that had a great future together, but that thought never came to fruition after King Lot´s sons Gawain and Gaeheris would assassinate King Pellinore as revenge for the murder of their father, this enraged Lamorak making her swear revenge against the Orkney family and to accomplish that wish Lamorak became a Knight of the Round Table. 
Eventually after so much trial and tribulations, so many bonds formed and burned, Sir Lamorak was able to get her revenge against the Orkney by becoming the Lover of Morgan Le Fay    Though her feelings for the Witch were true, her sons wouldnt accept them so they plotted to kill Lamorak... Even if she fought with everything she got and came close to killing them multiple times, Sir Gawain, Sir Gaheris, Sir Agravian, and Sir Mordred were able to best her after various hours of grueling combat... Thus bringing an end to the legend of Sir Lamorak of Wales
But… The servant summoned in front of you isn’t the Sir Lamorak legends talked about, in fact she doesn’t even share the same origin as the titular Knight of legend. She is nothing more than just a simple farm girl who was converted into the Monster you see in front of you simply because she was the only one left.    This girl originates not from Wales or from the Human world, but in fact was one of the countless Humans created to serve as “cattle” in the distant world of Fae Britain. She grew up on a village with nothing worthy of mentioning as she was never expected to become anything great in that world as Humans were simple tools for the countless Fae that existed there.    She was raised alongside another kid, a girl with Red hair who she grew into seeing as her own sister despite not being related through a mother or father, even if they didn’t have anything in that village the two still had one another to resist the endless hell they endured while serving the Fae of the village…    Sadly, her Sister was “adopted” by one of the most important Fae in all of Britain, being forced to leave the village, unable to take her sister with her as only she was deemed worthy… This left the green haired girl alone on the village, forced to serve her entire life those inhuman monsters whose cruelty knew no bound, she grew to hate those monsters… accepting that she would die in this godforsaken world    But that… didn’t last, not for good reasons sadly. One fateful day, The girl woke up to the roars of a Beast like no other… She couldn’t even get to the window in her cage before everything began falling apart, fire was all she could see as the screams of both Humans and Fae Alike drowned her ears…  
She barely escaped the rubble of the building that collapsed on her when she witnessed a sight she would never forget as long as she lived. She witnessed a gigantic beast like nothing she had ever seen, a dreaded Monster with the head of a serpent that teared apart anything it saw, devouring and crushing humans and Fae alike as if they were nothing compared to it…     The girl believed that this was the rage of the heavens themselves as nothing could explain the monster that was destroying everything, she would have become victim of its unholy rage had it not been that it got attacked by a Witch clad in darkness… at that moment she didn’t recognize who it was but eventually she would come to know that the witch who saved her was no one else but the ruler of all Fae Britain… Morgan Le Fae.    She watched the two fight with everything that they got, unaware of her sorry state, yet her mind remained conscious enough to see the Witch be able to “weaken” the Beast with all her magic… Unable to properly kill or send it away, but being able to make it kneel every time it tried to get up… When she saw the Beast not die after everything the witch threw at it, The girl with the green Hair tried to crawl away in order to survive, she tried to escape that place as if she was lucky, the Beast would leave once it devoured the Witch 
Morgan couldn’t continue this eternally as slowly but surely her magic was fading away as nothing she did could kill that Beast… She was too weak to try to send it to the past where she could have killed her so she could do nothing but try to find a way to stop it… in the state that the Beast was found, Morgan could seal it away in the body of someone in order to keep it contain until she could kill it… But with the slaughter that transpired no one was left to serve as the vessel of the Beast… that is, until Morgan noticed amidst all the fire and destruction a strand of Green hair that continued moving… almost as if it was trying to flee… Without thinking twice Morgan began using all the magic she had left in order to convert the Beast into pure Magical energy and seal it inside the conscious body of that girl she saw.    The girl was too weak to get up and run… she couldn’t do anything as she saw the massive wave of Magic approach her and forcefully enter her body… her dried and broken throat wasn’t enough to stop her from screaming from pain… she clawed deep within herself as if trying to get rid of the Beast that was entering her body, everything began turning dark as the roars of the beast drowned her everything… at the end collapsing, believing to have left this world after all the pain she had suffered.    But she didn’t die, far worse actually… She became trapped in her own body unable to move or speak, screaming in her mind as the only thing she could see was the same Beast that destroyed the world she had known… she couldn’t do anything else but to scream in fear and pain as the Beast tried everything to escape from her body without much success… The girl and the Beast were trapped in an endless cycle inside her body, forever trapped inside of it without any way of escaping. 
Eventually though… the girl was awakened from within her body… she couldn’t move due to all the pain her body was on, she could only see various of those damn Fae watching down to her… laughing and poking and slashing and crushing her with swords and mazes as if they were trying to kill her… with nothing they did even being able to free her from the constant pain she was on…     The girl started getting tired… furious… she hated everything… she hated her life… she hated this damn world she was born on… she hated them… she hated them all… she wanted them gone… And as if that hate was shared by the Beast trapped inside her body… she mustered all the strength left in her body and lunged towards them… she ripped them apart in mere seconds with her hands and teeth, ensuring that they all perished by her hands…     She most have killed hundreds of Fae, the same beings she once feared as almost omnipotent gods were now nothing more than simple meat bags for her to rip apart… She was eventually stopped by the same Witch that cursed her with that existence, the Witch didn’t even lift a finger as something she had done to her was enough to prevent her from even lifting a finger against her…     The Witch´s voice was kind but lacking any sort of emotion… She merely stated that now she would serve her… telling her that whatever she may have been before didn’t matter, she was now her Knight and she would follow her every will without a question… she called her “Lamorak” and told her that she would serve her as her enforcer to kill any Fae that went against her rule. 
“Lamorak” couldn’t help but laugh maniacally… she didn’t have anything, her own identity was lost and now the same Witch who brought that much pain to her was forcing her to become her attack dog… She laughed at the joke that was her own laugh… She had no choice but to follow that damn Witch… At the very least… she would be able to take all that hate she felt on those the Witch pointed towards.    With the years… Lamorak´s hate and pain grew alongside her… her every waking moment was agony but she couldn’t express it with nothing more than a Maniacal laughter. She couldn’t care more about what was happening, her entire existence would be that of a killer so FINE, she would be the best monster in the world… showing no mercy or regret against those she slaughtered.    As the Fae Britain grew, so did Morgan´s “Posy” of Knights grew, her rule became that of an Absolute Tyrant with Lamorak in the front serving as one of her most feared Enforcer, her deeds were such that she was even gifted with a Sword specifically meant to be used to kill Fae… Of course she tried piercing Morgan with it the moment she got it but she was promptly stopped… Lamorak stopped caring in the slightest and only did what brought her momentary pleasure in that forsaken world, slaying anything that brought her Pain.    The voices of the Beast remained strong, with it pressuring Lamorak to kill everything in her path… She would have agreed, she would have agreed to slaughter that horrendous world she was born on… if it wasn’t… that she met a “Princess” that was thrown aside like her… A Bratty princess that was taken under the wing of that damn Witch… A stock up brat that was raised to become selfish for her own safety. 
They butted heads time and time again, she tried to kill her countless times but the spell Morgan had used on her prevented her from even laying a finger on her… She hated her existence but… something about her made her continue to come back to hear her rant about anything in the world… They could be honest with one another with one another, say how much they hated that damn Fae world they lived on without fear of the other mocking them… Lamorak even heard the Princess´ most secret fears and desires as she didn’t care about what Lamorak heard as she would never speak…    That princess was… different to the rest, she was still rotten to her core and was still an inhuman monster… but she was one Lamorak wanted to see grow. So she contained all her intent of burning down all of Fae Britain despite the rage of the Beast just to ensure that the Princess would live long enough to become its Queen… she wanted to see her succeed so she could then face her directly at the end of it all.    So when those Visitors from the “True” world arrived… she was set on slaughtering them with no mercy… as she wouldn’t let them destroy the world she was going to burn… So they wouldn’t take her Princess away from her… Even if she had to devolve and let the Questing Beast take full control of her body… she would do everything to stop them once and for all. 

Excalibur Cataclysm, the Dolorous Stroke to end it all

This Noble Phantasm doesn’t really originate from one of Lamorak Alter´s own feats or from something the Lamorak from the original world did, it doesn’t even originate from something that Lamorak Alter usually owns, but rather this Noble Phantasm was one given to her by Morgan as an “alternative” to not use her “other” Noble Phantasm    Excalibur Cataclysm wasn’t the sister blade to Excalibur or Galatine, instead it was the Legendary Blade that the knight known as Sir Balin wielded which he used to slay a Lady of the Lake and subsequently used to cause the downfall of the Grail Kingdom by causing a Dolorous Stroke that devastated the Land in PanHuman History    Due to Morgan´s knowledge of PanHuman History through her merge with her PHH Counterpart and the tales of a certain traveler LB Morgan was capable of forging a similar Sword to that, calling it Excalibur Cataclysm and giving it to her best Anti-Fae Enforcer Lamorak Alter. Though this blade lacked the Potency that the original Sword Balin had it still functions as a Cataclysmic sword that can slay everything from normal Humans to even Fae. 

The Beast of the Futile End, The Yelping Monster that brings downfall

This Noble Phantasm originates from the Beast that lies deep within the Human named Lamorak… As in truth all of the strength this Humans possess comes from the Beast whose Quest was said to be fruitless, the same monster that haunted the Pellinore Bloodline since time immemorial… the Questing Beast whose existence signified chaos and destruction.    In Arthurian mythology The Questing Beast was a monster said to have the head and neck of a snake, the body of a leopard, the haunches of a lion, and the feet of a hart who was usually associated with King Pellinore and his descendants, being that it was their destiny to forever hunt the Beast in order to slay it despite how fruitless said quest was, its origins are forever shrouded in Mystery but some say that it was born from a woman who was tricked into sleeping with a Demon while other versions outright call it the Anti-Christ itself.    The Questing Beast was said to be associated with Chaos and destruction as its Quest brought ruin to the Pellinore Clan and that its presence foretold King Arthur of the downfall of Camelot through his Son Mordred, while in Panhuman History the Beast eventually met its end at the hand of Sir Pellinore and Sir Palamedes, in the British Lostbelt the Questing Beast had another Fate.    In there, it was taken by the will of Gaia itself in order to serve as a Terminal after their original Terminal Albion got severely damaged when facing against the horned God Cernunnos, its purpose being to wipe out all the life on the planet in order to let it heal itself but due to the Actions of the Witch Queen Morgan Le Fae The Questing Beast got sealed inside a young Human who would later be named Sir Lamorak, leading to her to use its power to slaughter everyone who opposes the Witch Queen    But… when the situation and requirements are met… The Barking of the Questing Beast will be heard again and it shall rise to fulfill its goal even if it has to completely overtake the Knight´s body
