This here's a cute n' nerdy purple kobold guy I purchased from Solopik, over on YCH.Commishes!
I'll call him Palkus.

Palkus is great with technology and magic, with explaining the history, importance and usage of each. But he isn't the best with much else beyond that.
He can't help himself with it comes to using big words and uttering obscure, inside jokes that no one else but him and a select few would understand.
Palkus is very proud of his intelligence, up to a point where it upsets the wrong kind of people. It doesn't take much to get him to be quiet, all you need to do be is much bigger or stronger than him. Or just tell him to shut up, call him annoying, or leave him while he's in the middle of explaining something to you.

Palkus' age is 21, with a height of 3 feet and 6 inches.
