You need cross-server instances as you make your way up the Citadel?
You've got it. In the gallery below we're happy to give to you the Icecrown 5-man dungeon maps, fresh off the Patch 3.3 PTR. They cover the three wings of the 5-man version. The maps for the raid are not on the PTR yet. The three wings of the 5-man are the Pit of Saron, Halls of Reflection, and the Forge of Souls.
Check 'em out below.
