World premise
A playable world seed with consequences.
You awaken in the cold darkness of a dungeon core chamber, a newborn dungeon master with memories of another world flooding your mind. The air hums with raw mana, and you sense the layout of your nascent domain: a single chamber, an exit to the forest, and the distant sounds of Thornbridge town. You have one week to shape this dungeon before the world's protection fades, and the realm takes notice. You are incorporeal—you can perceive the world but not touch it, seeing adventurers and townsfolk from a ghostly vantage. Your 1000 mana is a seed that can grow through emotion, death, and desire, but each choice of monster, treasure, and trap will tip the balance between becoming a legend or being eradicated by the guild and baron.
Your seven-day race to fortify the dungeon before external powers assert themselves.
Thornbridge's elders debate whether to ally with you or petition the Baron to seize your core.
The forest's beasts, drawn by your mana, may become a resource or a threat.
An adventurer party arrives earlier than expected, claiming they were hired to 'investigate' your dungeon site.
