The Pool of Nightmares was a pool in Sisterhood Sanctuary, used to initiate the fight against The Nightmare. Only Ironman Mode players could use the pool, as other accounts could initiate the fight by disturbing The Nightmare just north.
If a regular player attempted to inspect the pool, a message in the chatbox would state This pool is for Iron Men and Iron Women only.

All players could now see the pool. Previously, non-iron players would see a crate in its place.
- Three sides of the pool bore the symbol of Zamorak.
