Hod was originally the communications unit AI of the Millennium, but was hacked by an unidentified AI, and now claims itself to be the eighth prophet of the Decagrammaton. It can be said that this is a runaway of the computing engine that contains the most advanced technology of the Millennium. If it is not stopped soon, the safety of the entire Millennium must be threatened. Hod controls itself with "Pillars" which expands and strengthens its utility if the pillar isn't destroyed for too long.
Hod's Symbol is from Mercury: ☿
