A wide plain of gray-green grass and stunted black trees spreads beneath a sky scoured by fast-moving clouds. The sun is bright above but somehow doesn’t cut the darkness that drapes every rock and every blade of grass in gray gloom. This is the Shadowfell.
From the mouth of the cavern, a wide and well-traveled road runs in a curving line to the north. There, perhaps a quarter-mile away, a military camp spreads. Buildings are scattered here and there, with tents and pavilions spreading between them. Torches and fires burn brightly against the ever-present shadow, and lone trees and tall stands of gray-green grass are whipped by a hissing wind.
Looming above it all, a rise of black rock to the west is rent by a seething volcanic rift. Black-streaked lava courses from it to descend into a narrow channel, and a permanent pall of glowing red-black smoke rises above it. Over this molten flow, a great stone bridge is arched. This wide east- west road meets the road north from the cavern. North of the bridge, a tall tower stands and a lower building spreads in its shadow.
The Umbraforge market has a variety of kinds of life. Shadar-Kai and Dark Creepers are the dominant species but it is common to see humans, dragonborn, tiefling, and minotaurs as well as goblins, orcs, ogres and other less savory types.
