A Guest from the Future

Exploration Stage: Monster Hotel
From: Max O’Phobia
Description: I came here in search of a cure. I never meant to crash your party, only to... forget it. My name is Max. I can prove it. My ID is around here, somewhere. Shoot. Where did it go?
Completed: Thank you for finding my Entertainer’s ID. I must have dropped it during all the craziness earlier. I haven’t quite figured out what era you’re from, but I’m from the late 20th century.
