Saarthal is a very shy paca. He likes to be alone more times than not, and he typically doesn't do very well in social settings. Even when alone, he's fairly quiet and likes to keep to himself, and would much rather sit by a river at night, listening to and watching the water roll by, rather than going out and so much as getting a coffee.
His favorite time of day is night time, especially nights that are foggy and emphasize the glow of the mushrooms and markings on his body, or or cold, snowy nights that are silent as can be, all while being beautiful, however he won't protest a night with rain or thunderstorms either. Basically, he loves any weather that most normal pacas would consider "gloomy".
Living out in the middle of a forest, Saarthal is quite outdoorsy, but not so much in a working way, instead more so an adventuring way. He's always going down paths he's never been on, going into caves, or simply collecting nature things such a weird mushrooms or cool rocks!
