Project Tarot is the codename for three powerful sprites who were created pre-Matrix crash and kept in the sprite-equivalent of suspended animation at Fort Lewis. The sprites are a Jester, a Paladin (Solaire of Haven) and a Ninja.
During a break-in at Fort Lewis, Project Tarot is freed, although the Jester gets deleted by a fail-safe mechanism. After a short period of getting used to the new Matrix, they take up their original duty of fighting against Dissonance and return to the Resonance Realms. They take Firefox with them.
