[OOC: With 50 ft. of rope (the DM knows all...) doubled through the loop, the furthest Three Flower and Xielt could stand would be 25 ft., not quite enough to get safely on the steps. However, it might be enough...]
The Combined strength of Xielt and Three Flower is enough to pull up the stone cover, and the water begins to drain away with a loud slurping sound. The current quickly begins to pull on Xielt and Three Flower as the water gushes past them.
[sblock="Strength Check DC 12"]
Xielt roll 8 +2 = 10
Three Flower roll 14 +2 =16
Xielt takes 4 damage from battering.

[sblock="Xielt"]
This now makes 0/8 Grace and 15/17 Health. The Grace points will come back 1/minute with rest but the Health return at 1/day of rest. So he's taken some actual, physical damage from this rather than simple heroic John McClane style battering.

Three Flower keeps his footing but the tlaxu is again swept off his feet. He clings to his end of the silken rope as he is drawn towards the now widening whirlpool in the centre of the room...
[sblock="Strength Check DC 12"]
Xielt roll 12 +2 = 14

Drenched, bruised, half-drowned, the tlaxu nevertheless keeps his grip as the water pours past him. Soon the room has drained almost completely with just a few puddles left in depressions of the uneven floor.
The floor is covered in dark grey, lifeless silt. Beneath the stone plug is a well-constructed shaft made of fitted stone blocks. Metal rungs are set into one side and lead down into darkness.
From below comes the sound of splashing, incoherent grunting and the occasional clatter of dull metal...
