This is terrible newbie advice... mostly, no?

Since I don't really see the harm in it, let me clarify for you a bit

There ARE a few places in the shadow grove you can recall/teleport from. Now whether or not they are in the "shadow grove" type stuff I leave up to you to find. But there are a few sprinkled areas like the High Tower of Sorcery and the Elemental Temple that are separate areas completely that you CAN recall/teleport from ... mostly. I'm fairly certain there are places within the shadow grove proper you can recall/teleport from as well. But that's really what the attune skill is for finding.

As for the Nightgaunts, they won't cross continents. They can't swim, and they don't time travel... or for special consideration, they don't go into the past. Nightgaunts can be pretty tough, but they are kinda supposed to be. The POSITIVE to them sending from the shadow grove is that they themselves cannot recall/teleport easily so you can just expect them to do that and ambush the !@#$5 out of them while they prepare. People are creatures of habit and so are the characters they play.
