Consolidate the Dunwarren and Middledark regions to make the teleport spell more useful. Remove prevention wards from the Vaults, the In-Between, and Lower to reflect changes in the setting.
It is currently possible to teleport out of, though not into, the Deep Forge.
If prevention wards are removed, patrol points for current Warders to either cast 'a general abjuration spell', alarm or Ward Area at certain points would be nice (since they aren't allowed to use the Watcher patrol points) to maintain the wards. Don't really want Kingsley and her swords teleporting into Sanctuary :P
