What Luck Betide Us
Located roughly forty miles to the east of the Emperor’s Gate Inn, this mysterious factory was apparently built by planewalkers from Oerth. As part of the process, they cleared the land for several miles around the structure, possibly for materials and possibly also to maintain adequate sight lines. The factory contained some manner of portal to Sigil at its heart, and investigation determined that it was built by devotees of deep chaos as a site to build and experiment with chaositech.
Zealot Shadowhate came to Khemenelda in search of this factory, claiming to have encountered another such site on Toril. This factory was apparently built atop the site of a fellow planewalker’s hut, one which also contained a gate to Sigil at its heart.
