A world that keeps going while you are not looking.
Kings fall, factions turn on each other, and people remember what you did to them — whether or not you were there when it mattered. You cross into it as one soul among many. Everything you meet is standing somewhere real, and every die is thrown by the world rather than by you.
Close the app and the world carries on. Factions scheme, people move, rumours travel. When you come back you are told what happened while you were gone — including the parts that happened to you.
There is a box and it says what do you do? Type it. The world answers in prose, reaches for the rules where the rules apply, and remembers. Nobody wrote your particular sentence in advance.
Every check is rolled on the server, shown to you as it lands, and cannot be argued with. Death before you have proven yourself is permanent: no grave, no rumour, no name, no way back.
NeverLeaves is free, and it is paid for by adverts between chapters — never mid-fight, and never on the screen where a soul has just dissolved.
You can buy the adverts away for a monthly subscription. It is monthly for a reason worth saying out loud: every turn the Realm takes is written by a model, and each one costs something. A single payment for an endless world is a promise somebody breaks later.
There is one other thing for sale, offered only after you have lost a body: a small bargain that makes the next one harder to break. It belongs to that body and dies with it, and the game says so before it takes your money.
