Crown of the Abyss
Dimir the Three Fingered
Aasimar Ex-Warlock of Nezar, Martyr, Abyssal Worm for eternity
Dimir made pact with a Mysterious Entity, who later turned out to be none other than Nezar, lord of the Abyss.
Along with Rai-Harcole and Bergen, Dimir freed Nezar, Lord of the Abyss from his imprisonment.
Dimir betrayed Nezar in the last moment, earning his eternal damnation as an Abyssal worm.
Some obscure cults worship Dimir as a messiah figure due to his betrayal.
