8, 8, I forget what is for
Two Orcs (I see what you did there) need to go first in the description. Their motion will grab your attention.Stairs & sentries
A narrow chamber with the far arched exit to Green Pillars. Stone stairs creep along the wall and exit through the ceiling. The stairs arch over a dark doorway. The door handle is a carved wooden snake with spring loaded poison fangs (Save vs Poison or hand blackens and dies).
Two orcs (HD:1, AC: Leather & shield, Scimitar 1d6) are perched on the stairs, they will withdraw through the exit up the stairs if they spot light.
I have lost count---how many of your paragraphs are separate rooms? Maybe keep an updated tally with hyper-links at the top of the thread. Eventually, you can put the map there too.
