Crimsonwood 2

They may not be Grandmasters at all, just some tougher guild members in the PQ, or even new common monsters.

Taken from Q&A topic:

Q:What about monsters?

A:Mainly the bosses. None of which have been seen in any form, anywhere.

Q:Will there be new monsters that appear outside the PQ in these regular maps? Or will these maps be mostly populated by the current monsters?

A:Current. One of the things we noticed was people wanted more pure spawn maps aside from the caves, so think of the seperate maps as enemy guild halls.
