This trip into Surgeon's realm. We'll probably have enough people to split into groups . . . We've gotten Red to come along, so the best I can think to do is to divide him and Lepus between all the groups. They'll be the people we need to protect the most since we can't afford to lose Red's memory or Lepus as guides.
We don't know details about what his realm is like though—that has to come from Lepus and Messenger when he calls us to go in.
