been doing eridians from my fic as warmups, so meet the gorls (nongendered)!!!!

Uhura is the lead comm technician in Grace’s biodome. them and Zhurong are the leading authorities in studies of human-eridian technology interfacing, translating and transposing signals from one tech to the next. their workstation (named Houston) keeps contact with the Hail Mary while she’s in orbit, and is where Grace can easily contact other eridians out on Erid. serious, professional, practical, but very fond of Grace and his own dedication to his work and collaborating with eridian thrums. married to their job. kind of sick and tired of all the mate courtship attempts, too much trouble.

• named for Star Trek’s Officer Uhura, inspired by pink granite.

Leia is one of Grace’s students in radiology, biochemistry and visible light-related technology. they are the yang to Uhura’s yin. Leia is the team lead in studies of the effects of cosmic rays and ambient radiation, its uses, and its dangers. Also fascinated by earthling’s sense of sight and how it affected their technologies, and how to bridge that gap. bit of a freak about their field to be honest, can be insensitive in their enthusiasm, and often clashes with their colleagues because of it. it reminds Grace of himself when he was younger.

• named for Star Wars’ Princess Leia, inspired by plagioclase feldspar

i'm finally dipping my toes in the project hail mary/iron lung crossover content and like

i'm ALL FOR giving Simon a break, let him live and heal and be a person again in phmverse. but also consider. he brings in the cosmic horror with him and it just, keep clashing with the cosmic hope of phm

Grace's beach water turns to blood all of a sudden, the Eridians are scrambling for how the hell did that even happen. Also it has DNA matches with Simon and, a bunch of other humans, and also Grace at one point? -- Welp, more sources for cloned meat, and damn now we can clone fish too! Grace has sushi for the first time in decades.

Mary turns haunted, the Eridian team keeping the ship functional and studying the technology keep sensing humanoid shapes wandering and messing with the controls. Mary keeps notifying them, "foreign object detected", asking for the name of the unknown passenger, but there's never anyone there. -- The team names the ghosts, attempts at seances occur. No replies yet but they have a lot of human spiritual and religious sources to comb through, something's bound to work!

When they salvage Simon, he won't stop bleeding. They can't make it stop yet he doesn't seem to run out it. Endless exsanguination that human medicine cannot explain. Nobody has any idea how he's even alive at all. -- Rocky nags at Grace that he 'lied' about humans having bilateral symmetry, this one is all mismatched. Eridians get a crash course in proper radioactive waste disposal, and Grace discovers fucking gene manipulation agents in the blood.

There's some kind of fucked up eel swimming in the biodome blood ocean now, and it might be intelligent. -- Send in Grace and Rocky, first contact electric boogaloo.
