Skelos is a seeker of cosmic secrets that would be better left hidden.
Origin: He used to be a human scribe, but on his quest for secrets, he killed a snake in self-defense and a cult took notice. He was kidnapped and subjected to horrific torture, experimentation, and rituals. The result? He became what would be known in other places as a Yuan-Ti, but those places do not exist, and neither do Yuan-Ti.
The Nagas heavily despise the cults that create these WRETCHED ABOMINATIONS, and hunt them down, so Skelos had to flee.
His spellbook's cover is iron. Engraved on the front is a Memento Memori, a reminder of death, in his home language.
It translates to "We only dance for a short while, and then time demands its toll".
Outside of his search for secrets, he also wishes to construct a monument to his memory.
Skelos always wears a red-purple robe that covers himself utterly.
When he gets nervous, a decidedly non-human tongue will flick in and out, and a muffled rattling can be heard.
During down time, he will write. Like, a lot, Philosophy, observations, drawings of local fauna, diary, poetry, melodies, cataloging unknown creatures he meets.... (Probably after said creature is a corpse)
He likes evil, cruel sounding spells. But he is not a one trick pony and will have quite the disposal
.
Personality: Hates cultists, hates naga. Hates mirrors. Hates his form. Hates people who look normal.
Ideals: He would like to prolong his life for as long as possible, up to and including centuries if he could, but his brain is pragmatic and thus he would like to build a monument of sorts as quickly as possible, which would long out last him. (He knows he will die) The cosmic secrets he wants do include life expanding things.
Bond: He likes things that are engraved in solid rock or metal. He would like to inscribe secrets that he learns like that, perhaps on a big pillar.
Flaws: Over confidence tripping him up if he gets far ahead, being arrogant/dismissive of others due to being a cold-blooded yuan-ti as well as a sage, and being rather nihilistic and callous to life. Talking to skelos is like talking to an aberration at times.
