Arin used to be a war mount during a conflict between two countries, until he lost his horn during one of the skirmishes.

Me managed to rip his consciousness off his body in a desperate struggle to continue fighting.

After the war ended, he had no body to come back to, instead he spent years learning how to possess objects , speak, write, even basic things take whole decades when your mind isn't prepared for such changes, as he used to be just a an animal.

As time passed, and taking over objects, from wood figures, suits of armor, dolls and stuffed toys, eventually he came across inflatable toys, he could be lightweight, he could keep spare copies for emergencies, could still be a reasonable size to interact with others and not be extremely loud or clunky to move around.

He's developed a liking for Drinking and Gambling, mostly because those are few things that change over the years, no matter where he could go, there's always alcohol and betting.

He's kind of hedonistic, avoiding unnecessary risks and living mostly for his own gain.

Arin tends to smile all the time, mostly to hide his feelings from others, he also uses ilusions to appear "normal" in front of others, he also avoids contact while doing so, as the ilusions can only trick the eye.

He hates his horn being touched, and cheap drinks (beer), prefers sweeter drinks like appletinies.
