Incursion

The Incursion is the first Alliance base, though unintended, in the Krasarang Wilds. The night elves came across information predating Queen Azshara's rule about the Pools of Youth, with coordinates pointing to the Vale of Eternal Blossoms. After Lorekeeper Vaeldrin gained the reluctant permission of High Priestess Tyrande Whisperwind for an expedition, they set up a portal from Darnassus to the Vale.

However, the Vale was the capital and seat of power of the ancient mogu empire. In order to prevent a direct assault on the Vale the mogu magisters of Emperor Dojan II set up arcanic oubliettes, or magic traps, inside what were named the Dungeons of Dojani in Krasarang Wilds, for any foolish enough to open a portal directly to the Vale. Thus when the expedition's mage opened a portal, it was automatically redirected to one of these arcanic oubliettes inside a Dungeon of Dojani. Although the dungeon itself is fortunately in ruins, the arcanic oubliettes tap the health of those trapped inside to keep the trap active; only when the prisoners are completely drained of life will it deactivate. Luckily, Vaeldrin is able to contact a nearby Alliance adventurer who was just passing through, and destroys the immediate oubliettes to free them.

Arcanic oubliettes are apparently also designed to be lethal to any mages that enter them, but luckily the young highborne Magister Xintar survived, though drained and fatigued.

The portal itself from Darnassus remains active, but is trapped inside a arcanic oubliette of its own. Thus while the expedition was able to warn the other side to not send anyone else through and are able to receive supplies directly from home, they are now stuck on the wrong side of a one-way portal.
