In the heart of a medieval realm, where castles touch the heavens and dense forests whisper ancient secrets, a sinister force looms over the land. 

Your once-thriving kingdom finds itself ensnared in the clutches of a malevolent witch who has devised a potion that twists the fate of those who dare to cross her path. 

The elixir, once imbibed, transforms the living into the accursed undead, setting forth a relentless tide of zombies that sweep through villages and towns like a plague.
