ok, works for me.We're trying to work out a few hurdles on the way to that plan, I think.
It's within that range (as the crow flies, for sure). It's just over an hour's hike over often difficult terrain. (Hazardous, even, especially in the dark, or if you don't know the best route.) I'd put it at somewhere around 2 miles, telepathy-wise.
Yeah, that's good. Seeing as you didn't have the chance to voice your objections earlier, we can say that you left the Cairn with a connection to Lord Faldur, and that you'd tell them to "stand down" if the conditions of a good assault weren't met. Those conditions could include "if the Stone Giants haven't left" - which they haven't, yet.
