Cairns

Cairns is an independent metalsmith and woodworker who has a lot of ideas, he loves his anything to do with crafstmanship.

Despite seeming more introverted because of spending so much time on his own and in his workplace, he's actually quite extroverted.
Perhaps even an ambivert as he doesn't mind spending time on his own.
His home could also give others the idea of introvertedness as it's located more away from the main city/town, but that's just because he enjoys the more nature-y spots of his hometown.

Cairns also enjoys camping, going to the beach not too far from his home and pyrography.

Despite his more extroverted nature, Cain isn't the best with showing empathy or interest in others that well. He's quite friendly but won't get too close to most people.
Generally, he's pretty calm but can be quite excitable as well, especially with animals. He can secretly be a bit competitive.
