Back in good old Shattrath City, there's a new face at World's End Tavern. This is Zephyr. If you have Revered faction or better with the Keepers of Time, talk with her, and she'll teleport you directly to Tanaris.
This is Kalecgos in his human form. You'll meet him in the Magister's Terrace when he gives you the quest to kill Kael'thas himself. Remember to pick up the first step of the chain inside the first building of the staging area for the Shattered Sun Offensive.
Here's Kael'thas littler pet phoenix. One of my rogue guildmates got it after her first run, and showed it off to us in Shattrath City.
This orb, located right after the 2nd boss, will give you a flyover tour of the Sunwell Plateau when you use it. You'll see a few familiar faces when you do, but I won't spoil the surprise.
This is Tyrith. You'll get a quest to find him from the questgivers after you land on the Isle. Be sure to pick it up, it's the first step of the quest to kill Kael'thas and unlock Heroic difficulty. He's in the 2nd boss room, to the left as you come in.
Here's a lucky drop. All you tanks and enchanters are sure to like this. The bracers aren't bad either.
A brave Paladin charges forth to take on the Lord of the Blood Elves.
What business do a Naga, a Blood Elf, a Shivan, an Ethereal, and a Gan'arg have in the Sunwell? Speak quickly! But seriously, this is the third boss. She's rather like Moroes. Kill her friends, then kill her. Luckily, CC works liberally on these guys.
Not only do you deal with Blood Elves in Magister's Terrace, but it seems Kael'thas has recruited the Naga and the Ethereum to help him out as well.
Here we are, in the Hallway before Kael'thas' lair, preparing to charge. Only one more group of bad guys lies between us and glory.
This is Selin Fireheart, the first boss of Magister's Terrace. He's a lot like the final boss of Steamvaults, in that he will drain the crystals around him for energy. Every time he begins to drain a crystal, kill it before he finishes draining it, or he'll get a super buff.
This generation's Nat Pagle. Although, isn't he a little old for that?
This is Sun's Reach Sanctum, the building for the second phase of the Shattered Sun Offensive.
Bash'ir Landing in Blade's Edge Mountains, phased out for the "Intercepting the Mana Cells" quest. The Ethereals are still there, You just can't see them while phased.
This is the Dawning Square, an area of the Island occupied by Demons. The portal here pours out a constant stream of them, and many dailies require you kill them.
