I do my best to describe them to the others and continue to watch.
Do we have time to watch the compound for a few days to see if the four "Elves" enter the temple at the same time every night? Once we scope out a pattern, if any, we can decide when and where to breach the ice barrier.
In the meantime, Rubius will spend those days preparing grand feasts for all the heroes and all those in the castle. Everyone will be well fed and, hopefully, morale will be heightened. I also spend time learning recipes from the head chef and continue to make her feel appreciated.
