Blissenobiarella

Blissenobiarella, known informally as Bliss, is a character in Isaac Asimov's Foundation series. She is from planet Gaia, and she appears in the novels Foundation's Edge and Foundation and Earth.

Bliss is first introduced in Foundation's Edge as the escort for two Foundation men, Golan Trevize and Janov Pelorat, to be received to Gaia. Bliss, like all Gaians, has an enormous affinity for life and can't bear to see life destroyed. She is for long distrusted by Trevize while his partner Pelorat is quickly fascinated, until they become lovers.

In Foundation and Earth, Bliss leaves Gaia with the two men helping them in their search for Earth.

It is possible that Bliss is, in fact, Bellis Seldon, Hari Seldon's granddaugher who disappeared on a passenger ship with her mother, or at least her descendant.
