(Taking some liberty here, Yeoman, hope you don't mind. Just wanted to get this moving...)
On Catherine's advice, everyone approaches the ruin carefully. They are easily able to find an entrance, it has no door just a hole in the side of the temple.
It appears that the group can easily proceed double-file, but there is no telling what the inside of the temple holds.
Before anyone can say anything, Kaelan and Sepoto can hear at least two voices from within the temple. It appears that there are at least two people inside, though they appear to be engaged in conversation, and have not noticed the group yet.
(Ok. I need to know marching order, remember it is double-file.)
