Last War Of The Necromancers

Dumar, bio-engineered assassin, shoots himself in the head in an attempt to escape the purpose he was created for.
Upon wakening, Dumar finds himself in a plain, stone built room with simple wooden furnishings and no décor. He also finds he is paralysed.
Transported to another world by Grethron, a necromancer, to kill his brother Malthrom, Dumar realises he will never be free of the fate he has been created for, even killing himself had not changed anything.
Grethron takes Dumar to the palace to see the queen who apologises to Dumar for her brother-in-law’s defiling of his soul. Dumar discovers Grethron’s brother, Malthrom, invaded the kingdom before and is gearing up to do the same again.
Using his necromancy, Malthrom enslaves unwilling people to join his army and begins his march north.
Dumar is drawn in and honoured by the people but will he break his own vow never to kill or let the people he has come to care for suffer?
