Basically, loads and loads of people have bought and paid for Warden's Keep from Dragon Age Origins. (560 Points $7 ?€) and the thing is, it doesn't work.
Most people are having the same problem as me, you go to Dryden in the camp, agree to help him and he says he'll mark the location on the map and meet you there. However, the location doesn't appear and Dryden is nowhere to be found, hence money is wasted.
Here's some link to the threads that discuss the problem:
There are more out there if need be.
I either want ti fixed, or my money back, so far no word from EA or BioWare: that's where you guys come in! ;)
