An Alliance stronghold in Outland bears her name, the Allerian Stronghold, and according to Jeff Kaplan, "If you're Alliance you'll go to this base called Honor Hold, well Danath is actually there. And you'll run into him and eventually as the expansion plays out from zone to zone you'll run into all the heroes from the Valley of Heroes in Stormwind."
Alleria Windrunner first earned renown due to the sheer number of trolls that she slew in order to defend her people's homeland, Quel'Thalas, during the Troll Wars. With the help of humanity, the high elves ultimately prevailed against the trolls.
Alleria can not be found inside the stronghold, and, as Danath Trollbane tells her half-elven son Arator the Redeemer, her current status is unknown. However, with new raids and dungeons coming out such as Sunwell Plateau Raid, she may appear in the near or far future.
Horde players visiting Windrunner Spire in the Ghostlands can locate a necklace given by Alleria to her sister Sylvanas. The Dark Lady rages in fury at the messenger, but succumbs to her memories (see Lament of the Highborne).
