We did not. Please bear with me, as my knowledge on commonly accepted information on demonic mythos is...well, there is none. I don't know a damn thing, I've been pulling crap out of my backside this whole time. But this is what I've gathered for Na'lsa:

Na'lsa is a lowly demon, an extremely minor character serving under the guise of Gluttony. His existence on earth began millenia ago as he escaped by attaching himself to an amoeba that gorged itself (for an amoeba), which was quickly consumed by something much larger. He went on with this for centuries, piggybacking on to various organisms as he slowly worked his way up to larger things. Always able to influence, but never able to directly control. In the late 1800's, he possessed one of two lions that became known as the Lions of Tsavo. Feeding off of their life force and those they had slaughtered, he was able to sustain enough power to take a human. Those who have fallen to his influences have participated in armed conflict, the trauma usually enough to break their psyche and allow him a more direct means of controlling them. Usually under his influence or control, the host resorts to cannibalism.

So pretty much he's been feeding off of creatures for a thousand or two years now, becoming a literal example of the food chain. The sheer amount of things he has consumed has slowly given rise to his amount of power, but the sheer amount of human souls devoured has catapulted him immensely (for a demon anyway, I suppose). So in closing, he's the equivalent of a cockroach that has risen far beyond his station, and the time it has taken him has twisted his own mentality. What should be nothing has risen up to be something, but the question is going to be if he can survive when those he has risen above come calling.

If any of that is retarded, feel free to ignore it and I can write up something better for him.
