Nvordrakkar

The Nvordrakkar (or Horned Dragons), are a brood of dragons chosen and blessed by the god Hafrjal as his lieutenants to face the World Serpent during the Godswar. During the Dragonfall, they were driven mad and struck at each other, with only one of their number, Njardr, surviving the ordeal.

History
During the great Godswar, the Strom God Hafrjal recruited a number of dragons to fight against a terrible world serpent created by an opposing force. To do so, they were blessed by the god - their power increased tenfold and stag horns grew from their foreheads as a sign of Hafrjal's favor - the Horned Dragons, or Nvordrakkar, were created. A great battle ensued, and the Nvordrakkar defeated the world serpent and banished him to an extradimensional plane, bound by five seals forming a circle around a nexus of power.

However, even with their mighty blessings, the Nvordrakkar were not immune to the effects of the Dragonfall, an so they fell into madness and tore at each other. Only the one called Njardr survived; as he sensed the malignant energies arriving, he fled into the plane of Hafrjal, where the magic could not reach him. After the Godspact, as the final Nvordrak, Njardr would remain as the last guardian of the seals upon the World Serpent.
