The coins are for something else, but the water clue at least makes me think
of something. There's a really deep section of water at the bottom of
Akanon by the mines. I tried swimming to the bottom as a newbie, but didn't
have the air. Later, once my swimming was at a reasonable level, I did make
it down and tried swimming into the walls in all directions. I was really
looking for a passage or something like that. If anything was lying on the
ground and didn't stand out, I could easily have missed it. Anyway, it's a
bit strange for the 'abyss' to be there without a purpose. Well lets hope
it isn't just a newbie deathtrap.
