Ok, so, disclaimer: It's not actually a dungeon in the common definition of the term. The Vigilant is a massive airship used by the Paineel Erudites, abandoned by the Odus Erudites when the void leaked into Odus. The Vigilant sits silently above Paineel and watches the city like a hawk to protect it.
Even though the Vigilant is flying, adventurers will find a way to board it in EverQuest 2: Sentinel's Fate to brave the challenges within. The ship is broken down into three distinct dungeons -- Vigilant: Incursion, Vigilant: Infiltration, and Vigilant: Rescue.
But watch your step when you're in the Vigilant! The zone designer, Kyle "Kander" Vallee decided to insert a few areas where adventurers will be able to fall out of the ship to their deaths. So be careful up there, walk safely!
We have, as usual, a few screenshots of the Vigilant to show off to those interested. Check out the gallery of shots from the ship below and be sure to visit EQ2Players.com for Kander's commentary on the zone!
