Heiss

Heiss is the main antagonist of the Nintendo DS RPG Radiant Historia. He's in charge of Alistel Forces' Special Intelligence Division and is the superior of Stocke, the main protagonist. Heiss was the hidden wielder of the Black Chronicle, which caused him to maintain a low profile and use the secret book to alter events in history to meet his desires. He was also manipulating in secret the heads of the continent's main powers: Alistel  and Granorg, namely High Colonel Dias, Count Selvan, Queen Protea and General Hugo.

History
Heiss was the one to grant Stocke the enigmatic book, The White Chronicle, in hopes that he would find it useful. Which ultimately proved to be; as it, with the help of the Guardians of Historia, helped him travel through time in order to save countless lives, trump the conspiracies that were going on between both powers: Alistel and Granorg and ultimately save the continent from the desertification and the mysterious Sand Plague, which inadvertingly turned people into sand. The Guardians' only condition was that Stocke kept the powers of the book a secret; they and also warn him about the holder of the Black Chronicle, that's the counterpart of the White Chronicle, someone who would try to halt his mission using the same time-traveling powers Stocke now had.

What the protagonist, his friends and even the opposing forces of the kingdom of Granorg don't know is that Heiss is the wielder of the Black Chronicle and began utilizing its power even before the events of the game, altering history to meet his desires. Heiss was in reality, the brother of the late King Victor from Granorg and was the next-in-line to take part in a ritual killing used to stabilize Mana in the continent, that ritual was necessary to avoid what everyone knew as the Sand Plague: fluctuating Mana escaping from living beings, and them turning into sand. That ritual was to be carried out by the Royal Family of Granorg only, and if done by a courageous one that fully understood them through History, Mana was stabilized for many generations to come.

Heiss did not want to partake in the ritual and with the aid of the Black Chronicle, he only saw futility in sacrificing a good man for the sake of a selfish, vain place. He kidnapped the fair prince Ernst and fled Granorg. There, he used the Black Chronicle and turned his nephew into someone he could use in the future, he named him Stocke. He also altered history to finish off Raini and Marco's brigade so they could be assigned to Specint with Stocke. Heiss' ultimate goal was for the world to end, having lost all faith in it.

Near the end of the game; The Guardians of Historia, Lippti and Teo, reveal Stocke that all of the White Chronicle wielders have been sacrifices from the Royal Family and the White Chronicle helps them "gain character", while all the members of the Black Chronicle only see despair in the world and are bound by the tragedies of the past. They also warn him that Heiss has become too powerful, even for them, but they still have to avail by the rules of Historia. Still, they hint him about what's Heiss plans are and where he has gone off to to assasinate Princess Eruca, Stocke's sister. By breaking the rules, Lippti and Teo were painfully punished, but Stocke stops them before they say anymore and thanks them for their help. He faces Heiss in the Gran Plain and is defeated. The wielder of the Black Chronicle finally decides to stand up to Stocke and appoints him in the Chamber of Flux for the final battle. Before the event, he sacrifices Dias and Selvan to Flux and gains even more power. Stocke and his friends face off against all the powers of the Black Chronicle and multiple versions of Heiss from the Multiverse. The Black Chronicle is defeated and the antagonist recurs to using the powers of the Black Chronicle wielders past and takes the battle to Historia. Heiss becomes Historia's antithesis, Apocrypha. After the final battle, Stocke and his friends defeat it and Heiss crumbles away.
