It is eventually discovered that the bacterial life on Erythro forms a collective organism that possesses a form of consciousness and telepathy (a concept similar to the Gaia of Asimov's Foundation series). While the colonists argue over the direction of future colonization—down to Erythro, or up to the asteroid belts of Nemesis system—events catch up with them. Back on Earth superluminal flight is perfected, ending Rotor Colony's isolation and opening the galaxy to human exploration.
