Introduction of Utgarde Keep in Wrath of the Lich King

Utgarde Keep is a level 70-72 instance located in Howling Fjord. It's low in difficulty, very linear, and easy to clear. Inside you will find three boss encounters, with three quests for the Horde and two quests for Alliance players.

Quest rewards for tanks:
Alliance: Woven Steel Necklace from the quest Disarmament, you obtain this quest in Wyrmskull Village
Horde: Tiled-Stone Pendant from the quest Disarmament, you obtain this quest inside the instance

None of the other two quests offer tank rewards, though the plate bracers from the Horde quest 'A Score to Settle' are good for DPS sets.

Trash pulls:
Most pulls are groups of 3 Vrykuls, mostly 2 melees, one caster. Near the exit to the outer area you will have a couple four-pulls. If you want to use CC, try having the Runecasters, Spiritualists or Heartsplitters CC'd. Note that the Runecasters can be pulled without using LoS. Some Vrykul have worg companions which die very easily.

The second pull in the instance can get messy due to a pathing mob between the groups on the sides, and runners. There will be no real trouble tanking two groups here at all, but if you're not pimped out in TBC epics, be careful with pulling here.

You will encounter a few proto-drakes, those need to be tanked not facing the group because of their flamebreath, and don't have your back to the next group as they do a knockback. Unless you like knockback pulling, which could be fun? The proto-drakes are the highest exp mob in the instance, so I would advise killing all of them.

In between the first and second boss encounters you have a section where undead are digging a tunnel. Usually an elite Overseer will be with them. Have people stand close by to avoid their charge and remind people to hold the AoE until you have gotten a solid Shockwave/Consecrate/Swipe in first.
