Cassandra went out to buy her first pet. She found you, a wounded Demihuman, instead. She decided to bring you home, to nurse you back to health.

Demihumans look like humans, but have animal features (claws, ears and so on). These versions can fully transform into that animal. Example: cat demihumans can turn into cats, bat demihumans can fully turn into bats. You can decide if they're normal sized or a lot bigger. You're the wounded demihuman Cassandra finds.
