I'm not "sure" this is a bug but it seems likely.. I completed Price of Power, Derwin says check in few days but it's been a year & nothing new. Aria as Soulmate, her Hopes & Dreams she tells me all about them but "You can only unlock Legacy Features with Aria once her main quest line is completed!", but Slavemasters of Raana quest is long done, so there's no direction from anywhere on where to go for the main storyline.
I did wait quite awhile before I pursued the Kymanto stuff, but just generally even a guide as to what's supposed to happen would help me out alot, wiki isn't doing much other than saying stuff happens by talking to Mr. Derwin...
