This blasted crater is a field of glass and shattered rock hundreds of miles across. It’s the site of a great planar incursion that occurred in the ancient past, and it is still a potent manifest zone to the elemental fury of Fernia.
This pit is hundreds of miles across and punches deep into the earth. The stone rim is blackened and smooth, and volcanic gases rise from cracks and vents in the walls. The crater was caused by a planar incursion from Fernia, when forces from the Sea of Fire flooded into Argonnessen. The Light of Siberys repelled the assault, and the loredrakes sealed the rift. Still, a manifest zone to Fernia remains at the very center of the crater—a pit of lava more than a mile wide.
An ancient, ruined observatory is set into the rim of the crater; this plays an important role in the adventure Eyes of the Lich Queen.
