This plain wall hanging illustrates a doorway, which a word of opening causes to become a true passage.
Wondrous Item 13,000 gp
Utility Power Daily (Minor Action)
Effect: You unfold the tapestry and place it on a wall or other vertical surface adjacent to you. The image transforms into a real door, which opens into a 1-square-wide passageway up to 5 squares long.
The passageway lasts for up to 1 hour or until the tapestry is removed from the wall. If a creature is in the passageway when it vanishes, the creature is shunted to the nearest unoccupied space.
This power has no effect on surfaces that are magically reinforced.
