a long time ago there was few races one of them as been called the undead they was the perfect hunter's the other races was worried about the fact that after all the the primal animals will die and hunted they will hunt the races so they came up with a plan so they decided to murder all the undead a cold war was for so long the war keep been for a 10 bloody years so all the undeads died except for a three a sad couple with their newborn and they needed to sacrifice their self for he's safety so for their last breath the mom said "you will the undeads last hope I hope you could save our races, goodbye ace"
