The Necromancer of the Renowned Swordmaster Family

"I, Archimonde, summon the wardens of darkness and all their servants and soldiers! Heed my command!" With this incantation, Archimonde the necromancer unleashed hordes of the undead upon the continent. For a decade, they ravaged the land until the necromancer was killed by the hero Birkel Reinrandt. Two centuries and eight generations later, an infant born into House Reinrandt screams the very incantation Archimonde had once uttered. The necromancer has returned in the form of a baby, but will he survive the house of his once-mortal enemy this time?
