The party was slow to leave the earth fortress but in time Walker fully crumbled it back to the earth. The scene that they had witnessed last night was gone but not the same as the previous day. There were pieces of frozen blood crab shells and claws around the snow and sides of the streams.
"It looks like this is the aftermath of every night." Seeing so many pieces of the monsters, Gil wasn't sure how they wouldn't have noticed this kind of thing when they first scouted.
"I have a feeling that we happened to come upon a larger hunt last night. The sky was clear and there were a large number of crabs. The eels may have come out more because of that." The theory Su had made sense. It was most likely a night where more crabs just happened to come out for food or other reasons. The party just happened to be here.
