Bladespire Citadel (sometimes referred to as Bladespire Fortress), introduced with Warlords of Draenor, is a city for the Horde in Frostfire Ridge. Horde players arriving will help the Frostwolf Clan repel ogre attackers.
Despite the sheer size of the city, Bladespire is only a Horde quest hub. Instead, the Horde capital on Draenor is Warspear.
