Black Void

Black Void is a legal guild in the Kingdom of Fiore.

Overview
Not much is known about Black Void other than that they are a mysterious guild with powerful Mages. Their master never appearing at guild master meetings, and the mages themselves never being seen in broad daylight.

Although technically a legal guild, in actuality Black Void deals in under the table illegal jobs were the guild pulls off info brokering assassinations, and even village slaughtering. This is in part to the fact that most of the guild's members are former Dark Mages that were imprisoned for their crimes, but released to join Black Void as a form of rehabilitation. The guild's true master, Mephiles is actually an Etherious inhabiting the guild's ace Jason Gaebolg, adding to the mystery of the guild, as only Jason knows of the demon.

Strength
The guild is rather powerful consisting of mostly former Dark Mages. Although they are relatively smaller than most other legal guilds they have no problem going toe-to-toe with the most powerful guilds out there. Jason alone is said to have power that rivals that of former Grimoire Heart guild master Hades.
