Everyone runs, crawls and climbs as fast as they can before the giant centipede is done with Vortek, at least his brave standoff and ultimate sacrifice bought everyone enough time to get back to the entrance, Grabbles doesn't chase, at least not alone while his pet is busy. The mite's shout in undercommon echoes in the cramped tunnels as a mocking warning "If you ever came back here, we'll kill you!".
Everyone hustles to climb out and finds it surprisingly easy to do so, everyone except dog that is, who hounds and jumps from the bottom of the hole, biting at the vines with no progress, his whimpering catches Skapti's attention who climbs back down and tries to help him up, but dog is too big and Skapti too tired for him to lift the large mut off the ground - even so, how the halfling thought that lifting his mount 3 feet off the ground would help is anyone's guess.
In a hurry a rope is sent down to help tie mut and help him back outside, fortunately, the giant centipede was still busy in it's gruesome feast...
