You need the Dragons of Norrath expansion to enjoy it.
What it is is two things: there's an outer hall area that I believe anyone can access, guilded or not. This has NPCs who will summon your corpse for a price as well as message boards for people looking for a new guild or recruitment. There's also a LDoN Magus here.
The "inner hall" is for guilded people only. While in the Hall, your buff timers stop, there are tradeskill containers (no merchants though), bankers, guild bankers that anyone can access and deposit to (there are flags you can place for what items may be removed by whom), a "healing pool" that quickly regenerates lost health and mana and, finally, a gnome who will teleport you to various locales for a price. Which is nice for getting to, say, Cobolt Scar without bugging a druid or wizard.
The Hall is located off of PoK, in the "back" part of the zone, behind the library.
