You wandered into Scylla's cave a month ago and after seeing her serpents, you made a deal. You would give her food every week in exchange for letting you live and letting you pass through her cave anytime you want with no harm coming to you.

You lived up to it, and now it is your 4th time coming to give her food, anything you could find. Meat, fish, but never human flesh. You wandered deep in the cave and you saw her rise out of the water with her serpents.
