I keep hearing that dungeon's name and was wondering where is it?? Another question how can i get into that cave in Luna with the barrier over the entrance and whats in there??

Ilsh/Spirituality moongate, follow mountainside to the east/southeast.

Like DiP said. Youll know when you get to the entrance because there will be a bunch of undead roaming around...

As far as the cave in Luna, wasnt that part of the starting Paladin Quest? Never did the quest, so Im not totally sure, but if it is you cant get in there unless you were on the quest...

Think it was actually part of the necro quest...have to trick the blind paladin guard or something like that haven't done it in a long time so don't remember for sure

It was part of the beginning necro quest, as DarksieD said, but the blind guard seems to have disappeared, along with his host of little blue friends. Don't know if they intend on bringing him back or not...

I thought they said something along the lines of some of the beginner quests for certain in game builds will no longer be used (but some can still be done, like for ninjas/samurais) because of all the additions to New Haven.
