#Dungeon 23 Project - The Ruins of Mount Auyán (Day 014)

Returning to #Dungeon 23 Project - The Ruins of Mount Auyán (Day 006) we return to the 12 doors and take a look behind Door #5.

When you pass through this door you walk 10' and there is a stairway. If the party decides to descend the stairway they should be asked, do you really want to do that?  If they continue, then they start down a long stairway that is moderately steep and straight. Once the entire party are 15' below the original floor level the walls at the top snap together and the first few steps disappear. As you continue down the stairs the step behind you vanish and the walls come together. It is normal for this to not be noticed, you would normally tell them something seems odd, but they have to think to look behind them. Once they have descended 30' the come to a landing and as the last party member enters the landing the stairs are gone and the walls have all joined behind them, there is no way back. 

At the front of the landing (Area #69) there is an abyss that descends into the darkness. You are on the landing and on three sides are solid walls and on one side is the abyss. The abyss is 15' wide and on the other side is another landing and at the far side of it is a door. 

What do you do? 

If you dither for too long the side of the landing from the direction from which you came will start to vanish a little at a time. 

What do you do?

If they all or some of the party reach the other side, they will find the door very difficult, but not impossible to open. If they are unable to reach the other side, well it sucks to be them. But they should be able to reach the other side if they choose their equipment well and the party is not composed of dwarves, gnomes and hobbits.
