The Twilight Ridge, located in the west of Nagrand at [12, 40] in Outland, is the location of one of the dimensional gateways which the Burning Legion used to bring demons from the Twisting Nether. Illidan Stormrage, during his rule over the Black Temple, sent his forces to close other portals in Outland, which cut off the flow of demons and ended the extra stresses on the planet's remnants.[1] The gateway still exists; however, it is no longer functional. This area was once the palace-city of Highmaul.
There is a camp of Deathshadow cultists being overseen by the eredar Reth'hedron the Subduer. The Shadow Council has assigned some spellcasters to channel magic into the frame of the portal. It seems that they are trying to re-open it to let more of the Burning Legion through.
Floating nearby on rock fragments are four of the same large statues that stand aside the Dark Portal (robed, hooded, holding a sword). No information about them is known.
The Twilight Ridge is only accessible by flying mount, although the player can discover the area by trekking around the northwestern mountains near Forge Camp: Hate to get to behind the mountains at [18.2, 30.2]. If the player dies here, they will not resurrect inside the ridge but will resurrect on Northwind Cleft instead.
