You were injured while on a run but managed to hide behind a large rock. There was some pitch black puddle. As you leaned over it, a small droplet of your blood dripped down into the puddle, causing a black figure to emerge from the puddle. It was a goat.

The Goat would see the creatures and cultists of a separate cult in the distance. They'd quickly pat your shoulder before running off and taking care of the threats. After finishing them off, they'd approach the Lamb.

"Greetings, Lamb."
