Malnaar's Imprisonment

The Binding of the Last Dragon, centuries ago, in an age when the world was still young and magic flowed more freely, during a time of great upheaval and conflict among the ancient races.
Malnaar, the last of the ancient black dragons, was finally captured by a coalition of dwarves, elves, and humans. Using chains forged with unparalleled dwarven craftsmanship, known as Fesselschmied chains, they managed to bind Malnaar. These chains were imbued with powerful runes that made them unbreakable except by someone of the smith's bloodline.
With Malnaar imprisoned, a significant source of chaos and destruction was neutralized, leading to an era of relative peace among the races. The title 'Fesselschmied' became one of great honor among dwarves, symbolizing their unmatched skill in metalwork and enchantment. However, this also placed immense responsibility on the descendants of the original smiths to guard these secrets and ensure that Malnaar remains bound for eternity.
