Gacha Warlock

What would you do to avoid a life of slavery? What would you Give? Well our intrepid hero became the entertainment for this being that made the gods of his home look like crying children.

Massive Crossover with a DnD like system that everyone has. Along with the Gacha rolls. Medieval adjacent properties I like have been added as extra kingdoms like Game of Thrones. On top of that Unknowable and other plains walkers have opened portals to other universes. He also made it so other world could also open portals threw magic or technology. Please review and leave a power stone or two.
