[Zanti]

He may have been wrong about that also /shrug.

There isn't much said about this save many warnings on damaging outpost faction and a blurb from EQ Atlas.

"The faction hits for evil races and characters in this zone can be very significant. The faction is entirely on Venril Sathir faction, the same faction that exists in the Overthere outpost. Fighting here will quickly result in you becoming KOS in that outpost, which can be problematic for an evil character who is bound there to be."
