The Continuum

A league of civilizations, likely across many galaxies.

They transformed astronauts into the Apollo Eleven along with their direct representative L.G.M.. Their mission was to determine whether Earth was good enough to join the Continuum or was a potential threat that needed to be eliminated.

They used The Incarnate as their emissary judge, who first appeared in 1977.

They are likely on a higher echelon than the Galactic Council, which might just be concerned with more local matters. Starwoman, whose race the K'ntarians are a driving force on the Council, went to the Continuum on our behalf in 1982 when they passed judgement on Earth.
