Nico Swanson

A man of few words. He saw humans and their world, and thought to himself 'that'd be nice to try out!', so, he went and visited. Turned out what he tried out was pretty good! He learned he liked travelling, going to new places, meeting people, just going around from place to place, really. And when he learned you can do that as a job? To help other people travel? Even better! That enough was good enough reason for him to stay, and so, he did.
Like I said, a man of few words!
Personality
Nico is just a sweet and simple guy. To say it takes a lot to see him get upset implies anyone's ever seen him upset at all. Inconvenienced? Maybe. Agitated? Sure, but you're not gonna get it to really show up on his face. He just doesn't seem to have an angry bone in his body that way. That's not to say he's a man with no priorities though, because those and desires to boot!
He already loves getting to take people to places for his job, but not just that, he's someone you might just call a People Person in general. He loves parties, he won't skip an opportunity for a good meal and he'll make absolutely sure no one's left behind. To him, his sweetest memories involve him at a table with friends he hasn't made yet with a plate of good ass spaghetti for everyone around.
Maybe it's on the nose, but he doesn't care; To him, moments like that are Heaven on Earth.
