Characteristics:

Melancholical, sarcastic, a bit self-centered, good at listening to others, very unlucky.
Dreadfully scared of spiders and rats, obsessed with cats, coffee and playing the piano.

Lore:

Guillaz was a Sygnalus Swan that, after almost murdering his best friend Dragonfly, was exiled to Canilon permanently. The Gate, mysterious portal connecting the two worlds together, affected his appearance when he went through it, turning her into a monstrous creature. After many unfortunate adventures caused by Guillaz's appearence, she realized that she could shapeshift into a more normal-looking Dog, taking a new identity as an Africain wild Dog named Romain.

Romain feels terribly guilty for his past actions, leading him to attempt suicide in a bad depressive episode. After adopting the stray cat Mister Fancy Coat, Romain's mental health started to rise up. Him and his cat lived fifteen years together. After Fancy Coat's death, Romain spent about three hundred years living in his library, with his old books and numerous stray cats. No Dog ever noticed he remained immortal, the animal living in the shadows of Rascin, the town.
After spending so much time alone, Romain started to talk to himself a lot and isolate himself from the rest of the world, but also learned how to play the piano! She is very good at it.

But, years later, his identity got unmasked by two Dogs, Screebip and Scotch, who happened to be Sygnalus inhabitants in the past as well! The three became very good friends with time, and Romain learned to get used to Screebip's hyperactive personality and Scotch's weirdness.

Even though he tried to start new in this new life, Romain still misses his family dearly, especially Felna. There isn't a single day he'll spend without thinking of his lover.

Side note: Romain is a self-insert. I put a lot of myself into this character; thorough his lore, she has multiple appearances depending on his mental health: they represent how I dealt and still am dealing with depression myself.
Sorry for using you as a punching ball Romain you're still my favorite I swear.. 💔
