Only twenty-one will finish. The system runs once.

This is not a platform. This is not a service. This is a one-run execution system. Participation begins when fuel is committed on-chain. Fuel creates fragments. Fragments can lead to Thrones. Exactly twenty-one Thrones can ever exist. When the 21st Throne is confirmed, the system terminates permanently. No restart. No expansion. No continuation. Most who enter will not finish. Only the record remains. Will your name be there?
