Larkeicus Larkeicus is an elderly Clavat and the main antagonist of " " . Story . Prologue . Larkeicus is an immortal Clavat who gained his power 2000 years ago when he was hunting . He was once a respected scientist and had a Yuke named Veriaulde as his apprentice , creating machines powered by crystals . The power and efficiency of his machines led to a great civilization being built based on his inventions that allowed people to live with untold wealth and comfort , and as Veriaulde put it , Larkeicus was " worshiped like a god . " One day the crystals began vanishing sending the civilization into panic . Without the crystals , the civilization began to crumble , and its citizens collectively blamed what was happening on Larkeicus . The scientist began a mad search for more crystals , and in time learned that while the other crystals were disappearing , one crystal had suddenly appeared in a Forest . Veriaulde accompanied his master in pursuing the crystal , and according to him they had only intended to " investigate " it . Instead , Larkeicus killed the inhabitants of the village in the forest . When Veriaulde attempted to stop his master , he was struck down . The only survivor was Sherlotta who ran to the Crystal Core in the forest , followed by a sleek black cat . Larkeicus pursued her , and the Crystal reacted to their presence . Sherlotta was given immortality and ability to spontaneously generate Crystals . Larkeicus found that the crystal rejected him , would not power his machines , and harmed him . To the archaeologist his crystal was , as Sherlotta later words it , " worse then useless " to him . Since Sherlotta could now generate crystals he still had gained something out of the attack . Larkeicus captured Sherlotta and conducted experiments on both her and his student , Veriaulde . As an infinite source of crystals , Sherlotta could be used to help Larkeicus obtain immortality . Unbeknownst to him , however , the crystal ' s power had affected the nearby cat from the town . Sherlotta transferred her consciousness to the cat and used it as a substitute body and her actual body became a lifeless puppet that could do nothing but create as many crystals as Larkeicus wanted . The experiments on Veriaulde transformed the Yuke into a monster whenever he was exposed to crystals . Over time , Larkeicus concluded that the reasons for the crystals ' disappearance was caused by a shockwave from the future . He decided to make preparations to stop it and calculated that whatever sparked the shockwave occurred far into the sky , and thus started plans to build a tower to reach the point where the shockwave originated . Master Librarian . 2 , 000 years later , the civilization he built having devolved into a simple curiosity for archaeologists and treasure hunters , Larkeicus hunts in the Library for further research on the crystals disappearance . The hero first meets Larkeicus there while looking for the crystal sickness cure for Eryll . The townspeople hold him in high esteem , referring to the Clavat as a " respected archeologist . " Larkeicus agrees to brew this panacea if a Buffasaur horn is brought to him . After the horn is retrieved from the Aqueducts , the old man finishes the cure and gives it to the hero with the stipulation that some work must be done for him as payment . The medicine is brought back to the Forest , and Eryll is saved . The hero returns to Town in order to pay back Larkeicus , who reveals the location of Ice Mountain and asks the hero to repair the ruins found there , along with those at Fire Mountain . As each ruin is fixed , it rises higher into the air atop a majestic pillar . The hero returns to the Library after the Fire Mountain pillar arises , and is thanked and dismissed back to the Forest by Larkeicus . That same night , the archeologist ascends to the top of Ice Mountain and triggers a field of energy around the ruins at its zenith . The ruins atop both peaks fire a blinding beam of light at each other , meeting in midair and causing the Tower to materialize beyond the Gate . The hero is sleeping and is unaware of the old man ' s schemes ; however , the crystal in the Forest begins to shatter . Sherlotta , who had been staying in the same hut as the hero , reacts adversely to the crystal ' s breaking , and as it splinters , she shifts her conscience into the cat . The next morning , the hero awakens , unaware of the calamity that has just occurred . The black cat appears and runs off into the forest , with the hero in pursuit . At the placid pond , the crystal lies rent into tiny pieces , with only a faint bead of light at its nucleus . Eryll is there and asks the hero to gather the shards of the Crystal Core in order to restore the crystal and the village residents , who have all mysteriously vanished except for the hero and Norschtalen . Following a suggestion from Norschtalen that an archeologist might know what ' s going on . The Hero returns to the library and meets Larkeicus again , Larkeicus describes the history of the ancient civilization , and how it was destroyed because the crystals disappeared . Larkeicus notes the irony of this , because if it weren ' t for the crystals what he was trying to do couldn ' t be done , following this , he summons several minions and attempts to kill the Hero , but is instead killed himself . However , being immortal , the fact that he " died " was of little meaning , and when exposed to the Hero ' s fragment of the Crystal Core he is revived , and proceeds to taunt the Hero over the fact that the Hero wasn ' t familiar with immortality . This did not go on for long , however , as the crystal that revived him begins to harm him , alarmed , he throws the crystal away from him , and warns the Hero that if the Hero was the one who causes the shockwave from the future , then the Hero would die the next time they met , saying this , Larkeicus warps out of the library . Final Battle . Larkeicus does not reappear until the very end of the game , at the top of the Tower . He appears immediately following Sherlotta ' s request for the Hero to kill her true body , which was being kept at the top of the tower for Larkeicus ' s crystal generating needs . Because if she is dead then no more crystals can be created , and Larkeicus ' s plan cannot be completed , Larkeicus stops this before anything can come out of it , and argues with Sherlotta over the exact nature of the crystal ' s disappearance , Sherlotta stating that they disappeared because the world was ruled by corruption , whereas Larkeicus insists that the disappearance was scientific in nature , Larkeicus then denounces Sherlotta ' s faith based argument , and insists that his argument is the accurate one . Following this , Larkeicus absorbs a large amount of crystals from Sherlotta ' s lifeless real body , and attacks the Hero , but is defeated . Larkeicus applauds the Hero ' s strength , but notes that he was prepared for such resistance , and turns and absorbs a large amount of crystals from the real Sherlotta , transforming into a new monstrous form , and transporting himself and the Hero to an otherworldly arena to fight , despite this power , Larkeicus is defeated again , and regresses back to his human form . Surprised , but not concerned , Larkeicus states that no matter what , it is impossible to defeat him , because as long as he has the puppet Sherlotta , he has access to an unlimited supply of crystals to revive and empower him . Sherlotta attempts to attack him but is swiftly knocked to the ground , and once again absorbs crystals from her , so many crystals that Sherlotta loses her hold on the body of the cat that she was using . Larkeicus believes his victory to be guaranteed , but with her loss of control over the cat ' s body , Sherlotta ' s consciousness returns to her actual body , grabbing Larkeicus from behind , Larkeicus yells that she ' s only a crystal - generating puppet , in response Sherlotta generates a large crystal , the exact same crystal that appeared in the forest 2 , 000 years ago , both Sherlotta and Larkeicus realize that the reason that that one crystal suddenly appeared when the others were disappearing was because Sherlotta had made it 2 , 000 years in the future . At Sherlotta ' s insistence , the Hero shatters the crystal to Larkeicus ' s chagrin , Sherlotta notes that Larkeicus was correct in believing that the crystals disappeared by the actions of the future , and asks Larkeicus if he ever wondered why the shockwave originated so far off the ground . Larkeicus realizes that she ' s referring to the Tower , and Sherlotta observes that it ' s unlikely something could have happened this far above the ground without the Tower . Sherlotta states that the actions of the Hero were not the cause of the shockwave from the future , rather , it was Larkeicus ' s obsession to save the crystals that led to their disappearance . Larkeicus refuses to accept this , insisting that he couldn ' t be the cause , but this proved to be of little importance anymore , the crystal completely crumbles and sucks Larkeicus and the Tower into it , and the crystal is transported backward in time 2 , 000 years .
