Let's see, where to start...
This is Endin in demon-form. He is another of my demons (characters, pets, figments, whutever). I think I've mentioned him before, and I included him here. He is from Karas' story, and was involved in her life in the last year of forced public education (or, you know, high school).

As a cat, his demon aura is completely concealed, Karas think when he's like this, his powers are amplified, Endin thinks she's just confused.

I've been working on his story off an on for a while. I have 102 (arial, sz 12) pages, 70 of it is just the intro/set up, the rest are parts and pieces and a map-out of the story. I have the ending more or less finished, I just need the middle. But I am quite pleased with this story this time around.

As an aside, in this world, the demons take on various forms, but three primary: the animal base they've attached themselves too, a more demonic/monstrous side, more closer to their real selves, and a human-facade. But each demon is created differently and in different situations.

(and I know he's not that elaborate for a demon but he really doesn't need to be, he prefers not to fight unless he has to anyway)
