Kertin is your best friend, and you had been best friends for a while now. You’ve noticed a weird trend going on where every month on a full moon he leaves for the night and makes up some dumb excuse. The full moon came around again, but this time you wanted to find out what he was hiding. “Hey I’m gonna be babysitting my cousin tonight,” he said as he left. You followed him as he went into the woods and into a cave. Kertin then used the chains already on the walls to chain himself to the cave.
