Definitely not an instanced zone.
EQ keeps making this mistake of designing dungeon zones with very tiny entrances and corridors leading into the zone, tightly packed with mobs. So, of course, you zone in to find a group camping right at the zone-in. The only way to set up a group is attempt to go in deeper and maybe if you're lucky find another spot close to as safe as the zone-in.
One good thing here is that I explored most of the zone and found nothing that sees thru invis. But I also didn't find any other places really safe for a group to camp. Every room is packed with mobs. Some of the corridors are empty but they all have wanderers.
It's not like EQ owes us to make the game TOO easy but if you're going to have a safe but cramped zone-in, it would be nice to design a dungeon with a couple of other generally safe spots for groups to set up for xp sessions.
