Ah, The Lich King - Were You Expecting Someone Taller?

My group has met the Lich King!
We finally beat the guardian dragon Sindragosa and have begun our battle with the final boss.
This encounter has three main phases with a transition phase between each.
We have mastered the first phase now, and we've learned how to make a smooth transition into phase two. We ran out of time last week, but we will start the Icecrown Citadel raid from the beginning again this week. We will have to kill eleven bosses again to reach the Lich King and continue our battle.
