Patch 4.3 is adding three new dungeons to the game:
- Well of Eternity, taking place in the Night Elf city of Zin-Azshari immediately prior to the city's destruction and transformation into the Maelstrom
- Hour of Twilight, wherein Thrall's passage to Wyrmrest Temple must be assured during Deathwing's assault on the Dragonblight
- End Time, which is a distant future version of the Dragonblight following Deathwing's ultimate success and eventual suicide
While it's pretty likely that the vast majority of players will get to these dungeons through the dungeon finder, it should still be possible to reach them manually. Where are they actually accessed from? "Current" Dragonblight, or Caverns of Time, or what?
Bonus question: where is the raid Dragon Soul accessed from, for that matter?
