I'm never for splitting up of a group but if it is going to happen, the PbP format is the best for that as the GM can split his attention equally among his players without them having to sit around waiting for the GM to come back to the table for "their turn."
So... From this point on, for the sake of all involved, and most especially your poor DM, in the title bar, put whether you are in the "Advance Group" or the "Return Group" (Advance group being the group that heads to Enberton now while the Return Group is the group heading back to Tev'El Rhoe with the kobolds.) If things get too conveluted, I'll start a second RP thread for the return group as it might be quite a while until the two groups meet up again.
And... No worries yet, my friends, of this game dying due to my "overwhelmedness" if that be a word anyone can understand. I've run this adventure several times and though there are changes each time, the changes reflect the novel more accurately and there is little that can derail me... Though, I'm sure someone among you is more than creative enough to give me a run for my money

. The thing I like about running this adventure is it really gives me a fun way to do research on and for my novel.
I'm fully commited to running this game as long as there are players to play it.
I'll be working on a post with an updated map for later this evening. If possible, please post here what you'd like for your character to be doing... ie... Krueger will be heading off map toward the north along the woodlands toward Enberton. If you are moving toward the "fleeing/exiting/weaving/ect" kobold, put that... this way I can get a better idea of the map and where individuals are on it.
To those who are going to pay attention to this particular kobold... he'll be out of sight soon... so you'll have to make a decision now about him should you chose to do something that directly involvs him (Like shoot at him or chase him) Otherwise, he'll slip through the trees and brush and out of view.
