Poljen and Nyzahr both mentioned running up the tower, so among the PCs, I think it is just Lia and Fay in range.
As a suggestion for the third target, you could buff Tallis. She is nearby, and quite good with a bow herself.

Yeah, Targul's well outside the fort at the moment. His only path back up to the tower at the moment not blocked by a small army is the hidden tunnel which will take him a few minutes.
Dropping a rope is a possibility, though that is a long way to climb up.
Thomaslee, we haven't heard from you in a bit, I gather you're still busy. If you prefer, I can assume that Geoffroy is busy with the people down below for now.
