Character I made based off  FurLs 's Dragon Butler Universe!

Siero was a high ranking dragon that sided with the god dragons, and helped them in their efforts to eradicate humanity. Siero and his clan had access to high tier magic, mainly using it to hunt down dragons that sided with humans and humans themselves. During the conflict between the dragon clans, a group of dragons used a combined transformation spell on Siero. This causes Siero to transmute into a powerless cat, permanently stripping him of his dragon form. Unable to use any power, Siero has no choice but to wander the world as a cat.

At the start, Siero simply wanted to die. To him, this was a fate worse than death. He would spend most of his time reminiscing on his past and the power he used to have, trying to find some way to get his powers back. He tried on various occasions to get the attention of his clan mates somehow. But with no trace of Siero's past identity left in his new cat form, his clan kicked him out the door.

"Annoying pest.. don't come back here again" was the last thing he would hear from his clan leader.

With that, Siero decided he had to find a way to die. The pain of losing not only his power, but his clan, was too much for him to bear. In the forest near the headquarters of his clan, he found some poisonous berries. He was familiar with this type of plant, using it frequently to make poisons and the like. He knew it would take him out quickly. But while approaching the bush, a pact of bobcats jumped in front of him, trying to warn him. It was the first bit of compassion he had felt from another creature in a long time. These bobcats decided to save him- not because of his power, or his status, or his wealth- but because his life was inherently valuable. After a brief moment, with a change of heart, Siero turns away from the bush and walks away. Done with longing for death, he finds a way to survive.

After hundreds of years wandering the world and watching it grow, Siero found a great appreciation for life. Most of his free time was just spent exploring the surrounding environment. One day when Siero was exploring a neighborhood in his cat form, he bumps into the leg of somebody.

"Oooh, Master! Look, a cat!"

And from there, Siero met Finley and the dragon butlers. As a way to repent for his sins, even in a small way, Siero decides to become the tour guide for the dragon butlers. Showing them all the nooks, crannies, and wonders of the world. From beautiful sea caves tucked deep within the coast, to little-known restaurants around town that serve the best food. Who knows where Siero might lead them next?
