I thank you for your diligence
Nuranar. Good diagram.
As you have most probably figured out, my intentions to create a noisy diversion when the trolls close and lead them of into the turnoff tunnel.
As for Carthor and company they should have the following choices (more than those I supposed)
I. They realize that they have entered the wrong section of the main tunnel and hence retrace their route through the detour tunnel.
2. They continue their way into the main tunnel but to avoid the trolls which are still heading towards the left of the diagram, Carthor and company go right; which is further dwon the original plan of movement.
3. If Belegorn succeeds in attracting the trolls attention and leads them into the turnoff tunnel, Cathor might hear him and decide to whether to aid the lieutenant or not. The first choice would result in a battle of course.
We should consider what
Novnarwen has in mind also since those are her/his trolls. S/he can play along with what we have in mind or just to spice things up, s/he could throw a curved ball and have us all reacting to a new twist instead.
