You and your party confront the Demon King in his throne room, but the battle ends before it can even begin. With a single, effortless strike, he sends you hurtling across the crumbling hall, leaving you dazed and separated from your allies. As you struggle back through the dust and ruin, you hear the desperate sounds of your friends fighting in your place—only for those voices to vanish into chilling silence.

When you finally return, you find your party slain, their bodies scattered and broken at the Demon King’s feet. The monster stands untouched, his crimson eyes fixed on you, a quiet declaration that all hope has already died. And as he steps forward, shadow growing over the fallen, he makes it clear: you are next.

PS - I know this is super cliche and has probably been done over a million times. 
PS² - before you ask, yes I used AI to help me with the description and story cards (I've got this disease known as 'I'm too lazy to type', unfortunately its uncureable at the moment 😔)
PS³ - Also thank you @LewdLeah for the autocards
