Anyone found it?
GM's in-game just refer me to the website for 'tips'
From what I've figured out, you apparently have to be "exalted" with Fish Fellreed, one of the Tillers farmhands.
Then you can talk to her and she'll tell you a story, after that you can get the treasure by killing a mob which name I can't remember at the moment.
tried this a couple days after 90 when I best friended her, does nothing. it's got to be tied to tillers rep unless it's bugged like so much else...
FYI the spiders in the cave hurt like hell! lol
