South of the bridge is an area where Gnoll Reavers spawn.
There used to be spirit stalkers that spawned at night along with the Undead reavers. I am seeing Undead reavers spawn but no spirit stalkers. The stalkers look like transparent ghost wolves.
Also in the morning Undead reavers and spirit stalkers would despawn, but I am seeing often some still running around.
I think they started spawning at around midnight to 6 am.
