The black monolith of Kelly's Cove

Been playing rimworld recently. Created a team consisting of a maphia boss. his 6 year old daughter and his most trusted lutentent(and torture specialist) at some point in the first week in game. the child kelly. Found the monolith. Triggering eldritch horror. That ended in her death. After nameing the cove after her, The father went mad and attempted to kill the lutentent. Who survived and became the last one left. many weeks later a women in a black robe named Rosalyn showed up and started convening with the entities within. Then killed the lutentint. Becoming the new owner of this small cove in the middle of a rainforest world. she is bringing horrifying beings from the other worlds into ours. and feeds the harbinger trees their daily meat.
