During the aforementioned level you walk past a row of Stygian knights on display in order to get to the teleporter, which will attack you once you are in their midst.
However, if you keep your units strictly on the path while walking past them and do it in single file, they won't attack you (while creepily shifting their position to watch your every move), an interesting piece of advice for those who want to preserve their units.
Any idea why this is? Also, why are the Knights in the Mausoleum in the first place?
