Vampire-Hylden war

The Vampire-Hylden war (also known as the Ancient-Hylden war) was the name of the great war fought by the Ancient vampires and the Hylden, and the earliest known point of Nosgoth's history.

History
The war between the Ancients and the Hylden began because of the Hylden's open rejection of Ancients' God and his Wheel of Fate, which cast their souls in a cycle of reincarnation.

The war prompted the creation of a weapon with which the Hylden hoped to wiped out the life of the world apart from their own race. This was known as The Device, channelling the energies of a creature known as The Mass, constructed by a Hylden known practically as The Builder. The Mass was said to be able to destroy any creature with a thought, but lacked an energy source or personal sentience with which it could project its ability. Before a solution could be found, the Ancients defeated the Hylden, and constructed the Pillars of Nosgoth, which utilised powerful magic to banish the Hylden to the Demon Realm.

The Hylden did not go quietly, however, and retaliated as a last stand with a final Blood curse, turning the Ancients into Vampires. The nature of this curse was three-fold: To first impose an animalistic blood-thirst upon their noble enemies, turning them to savage beasts; to render them sterile and incapable of continuing their species, and thus, their magic on the Pillars; and to render them immortal, and thus unable to die of old age to naturally return their souls to the Wheel of Fate. As the curse became apparent, many Vampires committed suicide to rejoin their God who, in light of their new abilities, had gone silent to them.
