: I just figured the water was red because of all the iron
: all their buildings and statues were made of. Somehow
: it poisoned the environment or at least the rivers in
: their domain. And since the trow are immortal and
: don't appear to eat, I guess it doesn't bother them.
And of course, massive amounts of iron forging would involve massive need for fuel - thus, deforestation.

"When asked of the source of their animosity towards the Trow, all were silent. After a time the eldest among them looked down and seemed to weep, 'It was they who poisoned the soul of iron.'" -Forest Giant Flavor Text, Myth TFL
The soul of iron?
