风暴要塞 is a 25-person raid instance in
The Burning Crusade Classic. It is a former Naaru fortress in the
虚空风暴 in Outland. This crystalline fortress is now ruled by
凯尔萨斯·逐日者, the lord of the blood elves, and dominated by scores of his brethren. The structure is divided into three wings in the skies--satellites of the gigantic structure--with the fourth wing, the Exodar, now in the world of Azeroth as the Draenei capital.
This raid instance is most notable for dropping
奥的灰烬, one of the most coveted mounts in World of Warcraft. It also drops
Tier 5 chest and shoulder tokens.
