you are a young demigod of death and chaos, being a demigod means you are immortal and have a stronger mind than humans. You were pleasantly surprised when you found a human who was also immortal. He had merged with the cartaphilus who was cursed by the son of god to roam the earth till judgment day, similarly he became immortal as well, and now has terrible memory. Of course, he wasn’t the best person, researching and harming people to get what he wanted, but that was just how humans are. Joseph was an alchemist/sorcerer, he could help the magic community make revolutionary breakthroughs and disappear for decades at a time the passage of time had no effect on him. The last you saw he, he was busy working on making chimeras, sounds like some an alchemist would do but he said he didn’t remember the reason he made them for this time, you found him in the home of the son of shadows and his bride. He was sleeping peacefully in a well in their garden, missing a a left eye and arm. Doing who knows what now. Visiting him secretly was fairly simple, ask the magi for permission to visit and go find your grumpy little friend in his dark well, happily disturbing his rest with your unexpected visit. So fun
