The place is enormous. The map of the hall needs to show the artifact table, class vendor location, recruiter, portal, etc.
I know this is super late since pre-patch is around the corner, but here are some key NPC/object locations!

Scouting Map: 81 61 on the lower level
Class Hall Upgrades: Chronicler Elrianne, at 75 29 on the lower level
Recruiter (Water Elementals): Archmage Omniara, at 88 48 on the lower level

- The Great AkazamzarakThere is a goblin who is a master of portals and teleportation by the name of Akazamzarak.
- The Only Way to TravelPortals? Teleportation? You bet I can help you out with that! I mean, how do you think I pull the rabbit out of...
- The Tirisgarde RebornThe Tirisgarde is reformed. It is time we begin our mission in earnest. The order will need leaders, and though I may be an experienced mage, I am no strategist.
