Posted. Also, are we going to do the original attack of dark spawn because if not I had an idea, they could come up from the ground as a surprise attack.

I wouldn't discuss that kind of thing with the players unless I wanted to destroy all suspense. All I can tell you is what your character knows from overhearing scouts at the camp. The Horde is growing and it is closing. 

Also know that when you give me a suggestion, I automatically can't do it. The PCs are now expecting this twist so it looses all purpose.
