Eric and Osira returned back to the first tunnel on the left, up to to the second section not with Ratbugs but with rotten pieces of wood. The reason behind it? Well there is a opening exploded in the first section where all the cold can go in and dusk has set as they walked their way up the staircase. They need to go through this night with as much warmth as possible, how odd is it that there are a couple hundred of Ratbugs down at the storage room but not enough leather or fur up here to get a comfortable night sleep.
There are tens of men and women in this group, if they put in some work they can indeed strip some Ratbugs out of their leather to at least provide some warmth for the children and elderly, Mollara of which almost falls in the category since she is 49 years old.
