Dwarghar Stoneblood:
Dwarghar makes an awful racket of noise sputtering unnecessarily and complaining underwater. Since no one can hear him he keeps it up all the when he finds the curse curse cursing cursing lever he pulls it to one side.
Straining with much complaint.
Dwarghar learns a side effect of his water breathing potion (which tasted rather fishy) is his curses carry very well under the surface without bubbles in the way.
...but even louder is clang and clatter and grinding of forgotten machinery as in grinds into operation. Like the sun presenting itself after a very rude eclipse, a curved sliver of
sunlight breaks sideways through the water. As they notice the iron grating behind the sliding plug (with squares large enough to stick your hand through), the underwater pair feel the pull of the water's drain getting stronger. Likewise, Amalrik (who doesn't trust alchemy or any of that arcane mumbo-jumbo but was ready to assist, gills or no) feels a sudden current as he's drawn towards the grating as well.
