You were a knight once upon a time, you don't remember when. Your memory is now stingy with memories, some kind of war, a forest, a witch's house, your brothers are dead, and she left you to play, testing spells and poisons on you.

You woke up again in the night. Due to a recent session of magical violence, you didn't even remember where you were right away, the witch really does turn you into a house cat, all these potions and injuries make you weak and incapacitated, and the memory problems only help you bond with your executioner faster.
