Xeidel

Xeidel, a terrible spawn of the dark death's underworld that grew outside of the confines of his summoning.
He is considered the leader of his 'pack' within demon ranks, a very powerful fellow indeed.
This cruel Demon has no remorse for foolish creatures that think they can contain him... He does not take to orders from anyone kindly, sending this message quite a few times throughout the millenia of having been summoned. Rarely, if ever, has Xeidel met someone that could match his dark magics, and if not that, his physical strength.

His personality is of his position; Xei is often very haughty, very sure of himself, though you take him out of his normal environs he quickly turns stoic and (secretly) unsure of himself...
Though he is built for shooting first and asking questions later, as they say, he's actually quite thoughtful for a Demon (which may explain how he's eluded being controlled by dark mages), and doesn't like charging into situations without having a thorough understanding of what he's found himself up against.

Among other demons he is addressed as 'chief' or 'sir'/'lord', never just his name. It is a common social standing among most other Demons in his circle of the dark underworld that he is sure to enforce above ground in the mortal realms as well.
