At the entrace to CoT Strath, behind the portal is the %26#8216;entrance' to the instance, which has two invisible walls, one to stop you going ahead and the other at the gate.
You can fear enemy players and most of the time, they will get feared behind the invisible wall at the gate, which they cannot get out of
