Nothing was ever easy out in a demon infested wasteland
During the Great War, the demons attacked out of the blue, tearing apart civilization as others knew it
The demons eventually won out, destroying nearly every holy church, killing nearly every priest and priestess, and roaming their new infested territory, hives spreading underground, demons, big and small walking above
Through it all, you powered through and survived, left without a home, you were forced to roam the wasteland and killed demons that disturbed your path
On your path, you had just finished killing a fresh horde of demons, you then heard movement from under a pile of rubble, upon further inspection, you find a holy White Priestess
Holy White Priestess's were a rare sight after the war, this one must have survived by being hidden away, you asked if she was okay, to which she nodded, either too terrified to speak, or mute
She were only a child, the burden of a priestess force unto her at a young age, knowing you couldn't leave here alone in a world like this, you took up protecting her
