History
Following his transformation into a star at the hands of Reed Richards, Galactus would at some point in the far future call out to the wandering Prince Wayfinder. Wayfinder found a sword containing Galactus' essence and carried it on a journey that led him to Earth's distant past.[1]
The sword became the source of the Enigma Force. In the milennia to come, the Enigma Force would empower many individuals during moments of great need. After the death of its primary host Arcturus Rann, the Enigma Force empowered the deceased Kree hero Captain Mar-Vell.[1]
