The water boiled and heaved wildly. But one end of the crevice opened into other caverns. The cataracts turned as they fell, and thrashed through the crevice as if it were an immense chute or channel. By the orcrest light, Bannor saw in time which way the water poured. He poled the boat so that it shot downward along the torrent.
Isn't this the same magical water that ate a board from a Blood Guard's grip ... water that everyone was forbidden to touch ... now its just splashy stuff... why?
I suppose, just like the characters, it's nature is driven by the narrative, and so the 'magic,' evaporates without explanation 'cause its no longer useful to the author.
