Kolkirin is a demonic entity which embodies mortal desires, in the mortal plain he prefers to go by the shortened name, Kol. Although he is immortal, never ageing and undying, he associates himself with mortals more than demons like himself. Claiming to know and embrace the pleasures of the mortal realm, He attempts to distance himself from his plain of origin. However he still retains his demonic powers.
As a demon, Kolkirin represents envy and greed. He has a sort of bower bird obsession with the colour green which goes hand in hand with that which he represents. The powers he possesses are that of poisons and magic, using illusion, shapeshifting and summoned creatures. But do not be fooled, he does not hide behind his magic; he also possesses great strength and swiftness, but luckily for most, he usually only uses his powers to cause mischief.
He follows no master nor does he lead others, Kolkirin prefers to be his own person, although he may be associated with other groups of demons. Being somewhat laid back and not seeming to take things so seriously, he is mostly looked on by others as a sort of outcast amongst his kin. Though do not think him a coward, regardless of what powerful entity stands before him, if Kolkirin feels he needs to, he will confront it and speak his mind despite it. But keep in mind he will not go out of his way to anger or aggravate his kin, mortals on the other hand are a different story.
Overall, Kolkirin is a relatively carefree and harmless demon unless purposely provoked. Even though most catagorize him as such, he's not evil
... but that doesn't necessarily mean he's "good" either.
