A narrow fissure in the canyon wall leads through a gully choked with pale brush and shrubs. A swift breeze passes through the fissure. At the end, a dark, jagged crevice awaits.

The party runs into a guardian force of three hurricane monks plus the already injured hurricane monk from the spire.  It's a hard fought battle but they slice through the monks and continue to follow the tunnel from knifepoint gully.

An enormous chasm splits the earth as far as the eye can see in the pervasive subterranean darkness. A crude, narrow stairway hugs the rock alongside the chasm, twisting madly in hairpin turns around sharp outcroppings. Jagged and uneven, the stair threatens to spill travelers into the chasms mouth. After several treacherous miles, the stairway terminates on a broad, flat landing that juts out over the immense black chasm. In the gloom, a lost dwarven city lays in ruins beneath the glittering cavern vault. Broken statues stand in the midst of empty plazas, staring sightlessly into the darkness. A huge step pyramid rises at the edge of the precipice, and from the moat that surrounds it a misty waterfall whispers over the chasms ledge.

The carved reliefs of two dwarves face one another in profile to complete an arch beyond the ledge. Through the arch, the blocky contours of a lost dwarven city sprawl in the subterranean night. From somewhere within comes an agonized wail, followed by a breathless ramble of whimpering pleas. Then the whole city seems to join the chorus with the screams of creatures mad from torment.

The party walks through and into a zigzag gatehouse where the cries and screams are maddening and loud seemingly from all around.

A squat stone gatehouse stands at the entrance to the dwarven city. Beyond the open gates, an arched corridor zigzags past sturdy stone walls where arrow slits squint from every angle. At the far end of this murderous hallway stands the entrance to this lost dwarven city.
