The Warehouse of Amon'ley
This massive warehouse stores countless arcane treasures. The labyrinth of crates and barrels—some stacked 60' high—makes it nearly impossible to catalog the items mixed in with the mundane wares. Only Amon'ley knows where everything is, and he keeps it all in his head.
There is one entrance: through a massive sliding metal door, although Amon'ley has a portal in his small office. Two guard stations with archery slits flank the door.
Amon'ley uses the services of a huge half-demon ogre to lift and move the crates, periodically rearranging the crates to prevent any covert attempts to catalog.
