Neirealian

Neirealians are a race of space travelers. Their physiology shares characteristics with both plants and animals.  They require sunlight to survive, but must also ingest additional animal protein to remain healthy. Neirealians tend to be scientists and explorers, and take a keen interest in preserving biodiversity in the universe.

Glibberoid

Glibberoids are a race of deep space explorers, from a far away galaxy. They have ventured so far from home for so long that all memory and record of their homeworld has been lost. They exist upon vast world-ships, slowly drifting through the cosmos, harvesting resources from the worlds they come across.

They are known to be very socially awkward when dealing with other sentient beings, and abhor large gatherings.
