The Fallen Swords: Sins of the Past  

I've given some important information to the Duality, which he needs time to research. He has spoken of the mysterious fortress that has appeared over the Eastern Wastes. He has a theory on what the fortress might be, but wants me to gather a bit more information for him. He has asked that I work with the coldain, and to offer my assistance if they should need it.

I found that many coldain believe the fortress to be a bad omen for all of them. They mentioned a number of strange things happening since the fortress appeared in the cliffs, and indeed, I fought in a phantom battle in the Great Divide, and fended off a giant attack on the southern door of Thrugadin. After giving the information I found to the Duality, he made a surprising revelation - that the fortress is, in fact, Drunder, the Fortress of Zek.
