アイゼル

Ithere is a Dark Lord that belongs in the Hornet faction. 

He temporarily left Hornet's side along with Dark Lords Noce and Satella in order to obtain a weapon that would give them the upper hand in the war with the Kayblis Faction.

Under Noce's directions, he allied with Helman and invaded Leazas, not aware that Noce's plan was to resurrect the Demon King Gele from her imprisonment.

He was turned into a Dark Lord by Gele, which means he's from 1021 to 2025 years old. He's also had his apostles since Gele's era./
