His eyes are filled with wonders only he can imagine. Day dreams of survivors in other places, faring better than the rotting corpse of humanity that is Stronghold. He resents it, but has benefitted greatly from unearned privilege. Wealth he abhors but puts to good use tracking down lofty dreams among the refuse piles of those who came before and went in such a horrible way. Banal curiosity, or perhaps a tireless optimism? Who can tell.
Around people, he's a lively speaker and storyteller when the topic lands on his wheelhouse. Other times he listens, because the people he's chosen to call friends matter to him. Those are the ones he trusts and would do anything for, collected from around Stronghold in the most unlikely of places and strangest of circumstances. Life, in other words, which he's lived without regards to money or status, giving everything away freely as the need arises. A generous soul.
But secretive, too, about his true goals. His burning desire to escape the stifling control of Stronghold. Refusing to believe it could truly be the last remnant of humanity.
