Ryxon B'Al-Gare is a full blooded demon, and a prince of Hell. In fact, it's his nephew who is currently on the throne.
Ryxon is also an assassin under the employ of the Reapers, Hell's version of a special forces unit. His favored weapon is a scythe, though lately he's begun to despise his job.
His reason for hating his job is that he is the Host of DEATH.
DEATH is an entity closely related to the seven Sins.
DEATH and his 'siblings' have no physical forms of their own, and must share bodies with fitting Hosts.
Ryxon has a complicated relationship with one Cyrano Macomb, a human assassin who plays Host to DEATH's greatest enemy, JUSTICE.
JUSTICE and DEATH frequently oppose each other in combat. More often than not JUSTICE loses the fight, but every so often DEATH is beaten into submission.
DEATH is unbiased and interested in very little other than his job.
He collects the souls of the departed, and on occasion takes a more proactive approach and 'departs' people (human or otherwise) himself.
DEATH has a temper and a wicked sense of humor.
This results in Ryxon, when he loses and then regains control of himself, often being emotionally unbalanced. In a cruel twist of fate, the only person really capable of helping him pull himself together is Cyr. Fortunately for Ryxon, who doesn't see how this is possible, Cyr is always ready to pick up the proverbial pieces and put Ryxon back together again.
The two of them have been dancing this particular dance for years, but Ryxon is starting to grow uncertain how much longer this can go on.
