Jeyna walks in her wolf form into the hole in the wall, which continues its more or less structured construction and just keeps going straight. With it already being late afternoon, and your allies blocking the only source of the light, it is already very dark inside, especially the further you go in. The rope between the 5 of you has ten feet of slack between each. So for now the druid can only go ten feet before bashing who ever is next in line into the wall on the outside.
