Arma

 To describe Arma as loving his alone-time would be an understatement. He is often the speaker of common sense, but won't care enough to speak up equally much. Arma cares for himself, first and foremost. The plight of others isn't his business; he'd much rather be left alone. 

Not much has happened in Arma's life, which means his survival instincts; ergo avoiding everyone and everything has served him well. He wants no part of great adventures, he'd just like to uneventfully live out his life; forgotten by history once he passes on.
