Abaddon

Abbaddon is a powerful demon of the Inferno, holding the rank of Prince in the infernal hierarchies, and embodies the concept of destruction. Little is known about this demon, save for his grandiose ambitions and unusually focused efforts at realizing them.

Throughout history, Abaddon had ever schemed to visit destruction upon the mortal realms primarily through his chosen servant, the Harbinger (a role filled by Magnussen for most of the second millennium) and his legion of lesser demons. While most demons are content to influence their Possessed hosts merely towards vice, demons owing fealty to Abaddon strive towards guiding their victims into serving as his cultists. The foremost of these cults being the Cabal, which was led by the Harbinger himself.

Abaddon's plans came close to fruition in 1874, when he attempted to enter the mortal world in full panoply through a grand summoning ritual. This was the catalyst for the Portsmouth Incident. Unbeknownst to the infernal prince, he was fated to be thwarted. Though the forces of the Abyss attempted to induce an unreal timeline by assisting him in his victory, the Krewe managed to foil the situation.

With his Cabal in ruins, Abaddon's further plans remain shrouded by mystery.
