Age: Technically ancient. Actually 40, while aging slowly and looking like early 20.
Background: While his initial impression might be that of a demon, Yul's true background starts in a very distant past from roughly 10.000 years ago. Back then, technology was everything. Buildings reached up to the skies, it was relatively easy to communicate with people all over the world, and the world was at relative peace. The scholars of that time also decided to try their hand at creating life. In todays terms, we would call the result of that a homunculus.
One of those homonculi was created to stress test what was possible for these artificial bodies and minds, both mentally and physically. So it was put through rigorous training, and academic studies. All within reasonable limits. This was successful for many years and yielded great data. That homunculus was however, eventually gravely injured during a field test. A recovery via a regeneration modification was attempted, and the homunculus was put in storage to give the recovery process all the time it would need. But something must have happened. What exactly, he didn't know.
He woke up on his own when his storage pod eventually gave out. After trying to find anyone and failing, his only option left was to make his way out of there, by using what was left around him. And now was a good of a time as any to process everything. To start thinking for himself. What would he do now? Who was he? What was he compared to the people living here and now? Initially shocked to see the world around him, the homunculus hid, remembering his training. The world was... nice, but foreign. Putting two and two together took a little while, but eventually, he began to adapt. Make gear, choose a name, prepare for both hostile and friendly encounters. Not that this was easy however. Humans reacted with fear, mistaking him for a demon usually, making his first impression always a bad one. Still. Slowly but steadily, he managed to put his knowledge to use, and is by now making his money by producing and selling medicine at affordable prices. His best buyers are the merchant and adventurer guilds.
Personality: Yul is arrogant, playful, cynical, and opportunistic. While he wasn't always like this, years of getting called a demon eventually left a mark. But in truth, Yul desperately wants a place to belong. He is painfully aware that he is a stranger in the entire world. His world is gone. The people that understood him are gone. And he has grim predictions of the future if all the magic his world had did not save them. A thought that makes him laugh due to how absolutely tragic things look from his perspective.
A hint that there is good in him however, is his way of making money. Why make medicine when you could get richer with poison and death? Because not so deep down, Yul wishes for the world a better place.
