Hoppiqon

The native sentient species of the planet Hoppiq Minor, in the Horsehead Nebula, were pale-skinned humanoids.

Biology
They looked outwardly identical to humans and Homeworlders, save for their hair which had a strange feather-like quality. Their blood types varied but could include Q-Negative, a relatively rare universal-donor type. (PROSE: The Bloodletters)

Culture
The Hoppiqon culture, or at least the one to which Venn belonged, had a concept of marriage entirely divorced from romance — a purely practical contract undertaken between families, usually to settle the raising of the children once a pregnancy was noticed. Most had more than two partners, and there was a custom of "bundling" robust marriages with shakier ones in the hopes that the overall polycule would be more stable than the weak marriage would have been on its own.

It was also considered much more offensive to throw white eggs at someone's house than blue eggs, for reasons the Corsair did not entirely understand. (PROSE: The Bloodletters)
