Sealed Stairwell Chamber

Doorless Exit Container

When an exit doorway breaks, the indestructible stairwell remains inside an impenetrable rectangular chamber with no replacement opening.

Story so far

Former daughters in Turkey excavate the rubble after their exit door fails. They find the stairwell's containing structure, which resembles a large shipping container, but the vanished magical doorway has been replaced by a straight wall.

A Hole spell and Phase Through Walls both fail. The wall appears to use the same protected substance or rules as the original magic door, making ordinary demolition, digging, and movement magic ineffective.

Thus the stairwell technically remains on the floor while its associated key disappears and crawlers cannot enter.

Appearance

A smooth rectangular container exposed in rubble, glowing stairs visible only in cutaway behind an unbroken wall.

Role

The chamber lets the dungeon obey the unremovable-stair rule while functionally killing squads whose door is destroyed.
