Are you ready to take the fight to Deathwing? We hope so, because that's what you'll be doing in World of Warcraft Patch 4.3. Blizzard has released detailed blog entries outlining the three 5-player dungeons that will take you through time and lead to an epic raid and the assault on Deathwing himself.

The three level 85 Heroic 5-player instances will have you traveling into both the future and past to steal the Dragon Soul and use it against Deathwing. Players must quest through these dungeons sequentially to unlock access to them in the Dungeon Finder, ultimately leading to the 10- and 25-player raid with three levels of difficulty. Here's a brief overview:

1. End Time (5-man dungeon): Before you can travel to the past to find the Dragon Soul, you'll be whisked to a desolate future to see firsthand what happens to Dragonblight if Deathwing emerges victorious. You'll even fight familiar leaders like Sylvanas, Tyrande, Jaina and Baine.
2. Well of Eternity (5-man dungeon): Players will travel 10,000 years into the past to Azshara's palace to assist the much younger Tyrande and Illidan in a battle against the Highborne and Burning Legion. It's your job to fight bosses like Azshara and Mannoroth and obtain the Dragon Soul that's floating above the Well of Eternity. Of course, you can't stop the chain of events that lead to the Great Sundering and the creation of the Maelstrom.
3. Hour of Twilight (5-man dungeon): You'll then make your way back to present-day Dragonblight, which is now under a full invasion by the Twilight's Hammer. Players must escort Thrall and the Dragon Soul safely to Wyrmrest Temple, where the assault on Deathwing is to commence.
4. Dragon Soul (10- and 25-man raid): The remaining Dragon Aspects have gathered at Wyrmrest Temple to empower the Dragon Soul in an attempt to stop Deathwing. Players must thwart the attacking forces long enough for Thrall to charge the Dragon Soul. You'll have to defeat six bosses before you can take on the behemoth himself. The Deathwing fight is comprised of two unique encounters; the first will take place mid-flight, and the final encounter will be held in the depths of the Maelstrom.
