'Ald Fel is dwarven for "Stone Eyepiece". It was a dwarven megalopolis built in an active volcano. Ald Fel served as a waypoint in the great dwarven transportation system, this one incorperating the Node of Space. It later came to be known as Vilhan's Folly, when the dwarves pursuit of precious, magic-resistant orihalcum released beasts - including the Tarrasque and a Hellfire Wyrm - from the hellscapes of Nuegalon. To contain the demons, Ald Fel's orihalcum gate was sealed by a powerful enchantment that stated only a dwarf capable of facing the dangers below could open it. It was later opened by a party of adventurers which included Burne Ashenaxe, perhaps the most formidible dwarven wizard of the time. The gate has never been resealed, but it seems that most demons and undead released from Nuegalon have forgotten this access to the Prime Material Plane.
