In the past, Histonia emerged as a powerful magic user who was vying for the title of the "Great Demon King", becoming one of the Demon Kings of the Silver Water Holy Sea. Eventually, he established his own domain in the Silver Sea, where he ruled.

Abilities

 * Immense Magic Power: Histonia has a vast amount of magic power, as he was considered formidable enough to be recognized as a potential successor to the Great Demon King Zinnia Shivaheld, as well as being acknowledged as a member of the Inviolable Waters, a group of extremely powerful beings that are renown across the Silver Water Holy Sea for their power.
 * Magic Deepening Mastery: According to Yzak, unlike other magic users, who had to deepen shallow spells through the use of Fire Dew, Histonia was capable of deepening them without using Fire Dew, as he only needed to use his magic power in substitute.
