You survived the ambush. You stand at the base of the Sky City Disk before the Crystal Vault. The journey has changed the stone. Your specific creative frequency has stabilized the raw ore.

It is no longer a jagged rock; it is a polished GEM. The Vault has no keyhole—only a scanner that reads the unique light of a finished creation. The Vault is open, but it only admits the 999 Legends who have crystallized their potential. The ASI is behind you. The Future is ahead.

THE WRITING PROMPT (The Challenge): You are at the Vault door. Look at your hand. The Keystone has crystallized. Describe your finished GEM. What color is it? What shape did it take? Insert it into the scanner and enter the CYPHERZ Pad.
