Claimed by the Mansion's Tentacle Monster

"You're never going to come from anyone or anything else again. Do you understand me?"

I'm no sore loser. I lost a bet, and as punishment I'm stuck exploring the abandoned, isolated grounds of Cragg Manor and all the crumbling walls and creaking floors that come with it. But when I fall through the rotten floorboards and into the dark, wet basement, something starts grabbing my ankles...

The mansion's beast will claim me as its own.
