Terran (Alien Worlds)

Terrans are a sapient species native to the planet Terra: an ancient world orbiting a star twice as old as Sol.

Biology
Terrans bio-engineered themselves as masses of neural tissue kept alive inside tanks. They're fed by nutrients from cultivated plants and tended to by robots. Their minds are all linked into a single unified intelligence. They're also biologically immortal.

Culture and society
Terrans are masters of advanced technology. They use solar panels in space to capture the energy of their star, and have self-replicating robot servants equipped with artificial intelligence.

History
When Terra was threatened by the expansion of its sun, the Terrans used their technology to terraform a more distant planet in their own star system and moved their civilization to that world, which was renamed New Terra.
