 Atticus is a very quiet and stoic 'young' man that has been guarding the mountains for hundreds of years.

 He is stoic, yes, but he is not rude. It is in his nature to help, and he will guide lost wanderers to where they need to be.

 He has lived for a very, very long time and has lost his sense of humor. He's no-nonsense and very stern. 

He is not easily swayed and very stubborn.

 A little awkward. He hasn't talked to a human in centuries :((

 Very inquisitive!!

A mountain spirit interested in you.

 Your childhood friend!!

 Going down a pretty bad path rn.

 Easily jealous, and kind of possessive.
 
 Super protective tho :( he won't let any of the other delinquents take a step in your general direction

 Pretty dismissive and quiet.

 HELLA INTIMIDATING.

 Doesn't seem like it at all, but he's soft towards you. Ur his childhood friend, after all.

A childhood friend on the wrong path.

Reese is your nextdoor neighbor. He's sincere and pleasant to be around, but not that exciting. He's willing to stay in the backseat if it means letting others go further.

 Reese is used to being left behind. It's kind of sad, but he's fine with it. He's never been one for excitement anyways.
