Hallabor is an Underdark passage that begins at the labyrinth Geledh. Going east, it passes into the gates of Phaerssysn.
Two thousand years ago, Hallabor was a road of commerce between the Volgads and the drow of Phaerssysn. The road was expanded and maintained by the Šukhan. When they were a mercenary company, the Šukhan were sometimes employed by certain drow houses of Phaerssysn. When Imrik fell, the Volgads fled north. For a time, Hallabor became a raiding passage for occupying the ruins beneath Imrik and Geledh .
