[Suzerain of Sheol]

I've never used this one on any other site. It's a reference to Abaddon from Revelation, the Angel of the Abyss. Sheol is the ancient Hebrew underworld, predating the conception of heavenly reward for human souls, the spirits of the dead were interred there to await the final judgment at the end of days. It bears some similarities to the Greek Hades and is often substituted for it in biblical translations, just as Gehenom and Tartarus are often interchanged.

...yeah.
