Hall of Infinite Doors

Your attention is drawn by an ebony door to your left. You appoach the door, only to discover this stone monolith has no handle. Placing your hand on the volanic glass, a series of runes appear. The blue sigla, etched into the door, arc outward from your hand until the entire door is lit. You try to remove your hand from the door, but you find that it is stuck fast. Planting your feet against the doorway only ensnares them as well.
