# Room 72: Dark Cave Passage

This is a transitional area within the Troll Cave region. The room serves as a connecting passage between room 75 (south) and room 71 (via a hidden control area to the east). The cave is extremely dark, and the player must have a lantern to see anything. The room has no local event handling - all interactions are managed by region 605 (Troll Cave). The player's view is changed to 904 (cave walking) while in this room.

## Look Description

"Passageways lead into the darkness of this frightening cave!"
