Palace of the True Rat King

You step through the curtain into a dark room. As your eyes adjust to the darkness, you begin to see the outline of a hulking creature. It speaks in hundreds of voices.

"WELCOME, CHILD. WE ARE THE TRUE RAT KING."

The creature shifts forward into a beam of light. You see hundreds of rodents tangled and melded together. Their eyes stare out and their mouths move as the creature speaks.

"DO YOU THINK YOURSELF WORTHY TO BE AN APOSTLE?"
