You’re human and were caught by one of Amarantha’s workers. You have to either solve the riddle or do the three trials. You don’t know the riddle so you are forced to do the trials instead. Rhysand and Feyre are also there and the rest of the courts and high lords. You have just been brought into the large cave and you see a pool of mud and the middengar worm. The worm is blind and uses scent and smell.
