History
In mythic times, Elasarius was the spark that created Celexei. According to legend, Elasarius conceived of Celexei through a dragon. It is unknown if he was the direct offspring of Elasarius himself or if he simply willed Celexei into existence by the dragon. Elasarius treated Celexei more as a project than his offspring, creating him for the purpose of experimenting with another semi-divine life form as the other gods didn't want to leave themselves to the whims of Elasarius.
Over time, Celexei proved rebellious and difficult due to his draconic heritage. Elasarius gave up and cast him away. Celexei would come to join the Infernal Order, becoming the source of necromancy and black magic as the rival of Elasarius.
