The shadow doesn't open up to the outside, since the hull prevents that, so the Gamma will just have to go somewhere else. As Tyki and Lambert clean up, Shimmer will set upon those that have fallen, making sure to put them all out for sure with her magic. It seems to go well.

After that, there won't be much getting in the way of them reaching the section Tyki has mapped out in his visor. Anything you want to do before proceeding?
