From publisher blurb:
The area now known as The Seething exists at a nexus of ley lines high in the mountains. The atmosphere is sharp and strange, and an indelible electricity courses through every feature in the landscape. Its properties made of this implausible country an abode of great magi and of those who wish to peer past the panoply of green veils with which the modesty of nature enshrouds itself.
Such individuals notoriously prefer seclusion to liaison and soon fell to quarreling, intrigue, and mass murder. The Seething, while still, yet seethes, profoundly contaminated with the radiation of dweomers past.
But they say there’s treasure so, y’know, prolly worth a look.
This module contains three strange edifices left over from the time of the War Wizards--one now occupied by a mad sylph, one taken by the fearsome Panoptikhan and a still-functional automated outpost of hell known as the Demon Factory.
