BALLAST
A tower sinks into the mist, because memory has weight.
Aethelgard is a vast tower threaded on an endless chain, sliding down it into a bottomless mist. You are a Ballast: a convict thrown to the bottom to drown, pardoned on one condition. Carry the Codex, a book that draws the world's weight into itself, to the Winch at the top.
Ballast is an idle game with Soulsborne bones. You don't play the fight; you prepare for it. Pick the zone, the loadout and the rules, read the forecast, and combat resolves itself from your plan.
Every page you bind into the Codex makes you stronger, and makes the book heavier.
