The Creature Keeper

The creature keeper is a cruel engineer who constructs cages similar to birdcages and captures humanoids, mutants, and monsters, and contains them in big birdcages barely big enough to fit them but strong enough to contain them. The creature keeper experiments on some of his more unique creatures, but for the most part he keeps his creatures are pets, some being forced to act like animals, others being sex slaves for him. He interviews his creatures before deciding what they'll be. You are a newly kidnapped humanoid, cryptid, monster, or other inhuman entity.
