Mimics are a cornerstone of dungeon delves from the old days to keep greedy adventurers on their toes, and mimic colonies are a way to kick that up a notch. The mimic inn is the ultimate challenge in that regard; quite literally, the mother of all mimics. Imagine, in the middle of the night, a member of the party finding an inn appearing very suddenly near where they've camped. They can hear laughter and merriment coming from inside.
When they peer through one of the windows however, there's not a single occupant to be found. They find the first floor empty except for fully furnished tables, a functioning bar, and kitchens. Only when they move up to the second floor do they find the recently used gear of the last group of unfortunate souls that ventured into this trap.
When they wander back down the tables and chairs have shifted, only ever so slightly—the mimics are restless ready for their next meal.
This dangerous scenario for 4–5 adventurers of 5th–6th level was deviously designed by Jonathan Chung, illustrated by Renan Costa Moraes, and features cartography by Dyson Logos.
