Gotred Onjur was eager to learn more about battle strategies for the Undead, and was looking to add to his so far victorious force. Having been denied a battle with a rival Vampire, he observed a confrontation between a third Vampire force and the forces of the Empire. Meanwhile, he had ordered another Necromancer in his coven, Costarov Davest, to rendezvous with him, bringing a small troop of Black Knights and carrying the Book of Arkhan.
Unfortunately, Costarov's force was waylaid by the very same Vampire that Gotred had been previously looking to engage in battle. Costarov disobeyed his orders from Gotred to avoid combat and safely deliver the Book and the Black Knights, and rushed headlong to meet the Vampire's oncoming force, a mistake that was to lead to his doom. The enemy was sighted, and it was only then that the opposing force was found to comprise a number of ghostly apparitions which Costarov had no answer for.

The Battle
Costarov had one chance. His magic was more powerful than that of his foe (he had Invocation of Nehek and Wind of Death as well as the Book of Arkhan. the Vampire just had the spell Gaze of Nagash). If he could divert the Hexwraiths long enough while he did as much damage to the bulk of the Vampires army as possible using magic, then weight of numbers might be enough against the Ethereals.
The plan didn't work. Sacrificing the Dire Wolves to buy time against the Hexwraiths provided only a temporary reprieve, and when he did manage to get a Wind of Death spell to run through the Skeleton Warriors, it was largely ineffective, slaying a very small handful of them.
Costarov backed up with his Skeleton Warriors, hoping to get more spells off, but the Ethereals were fast closing in. Meanwhile, the Hell Knight heard Gotred's telepathic summons, and turned his Black Knights to leave Costarov to his fate. Getting bogged down in a fight against such numbers would only mean the doom of the Black Knights as well.
The Zombies provided a temporary shield on Costarov's right flank, holding up the Spirit Hosts and even the Vampire for a short while, until the Vampires own Skeleton Warriors rushed in to finish them off. Twice Costarov tried to unleash a deadly Wind of Death into the ranks of the advancing undead, and twice the magic backfired, streaming not through his enemies but into his own ranks.
Costarov made a final desparate attempt to make a break to get away from the advancing forces, with a Cairn Wraith attempting to single-handedly slow their advance while Costarov tried to use the Book of Arkhan to give them some momentum. However, he was unable to summon the power to use it, having spent much of his energies summoning the Winds of Death. The Skeleton Warriors of the Vampire crashed into those of the Necromancer's, and were subsequently joined by the Spirit Hosts and Hexwraiths attacking on their flanks. The beleaguered Skeleton Warriors and Costarov fought on valiantly and to the end, the Necromancer himself even felling a Skeleton in hand-to-hand combat, but it was to no avail.
The Black Knights did not even notice the demise of the Necromancer, nor did they care. Their only concern was to report back to Gotred Onjur concerning the failure of Costarov and the loss of the Book of Arkhan.
