A series of bridges interrupt the narrow footpaths within the suspended maze leading up to Iban's Temple, at the very heart of the Underground Pass dungeon.

The chasm where a player lands after failing to cross a bridge.

There is no Agility level requirement to cross the bridges, and a successful crossing does not grant any experience. If the player fails to make the jump, they will fall into the large subcavern below and land amidst the soulless, taking up to 24 (20% + 5) Hitpoints of damage in the process. They will then have to use the staircase in the north-western corner in order to climb back up.
