Having another species with bones could shake things up, since my personal headcanon is that humans and goblins are pals (semi-jokingly) on account of being the only two sapient species with internal skeletons - such that in an older version of the setting with more defined factions (before I sidelined those to focus in specifically on food-related things) a good chunk of all humans and goblins lived in a big fleet of cobbled-together ships and space stations together.
Other highlights of the old forbidden Astro-Gastronomy lore include hobbits/halflings as friendly slug people who I believe were often found among the ranks of aetheric scholars (I ended up cutting them since I couldn’t very well call them Hobbits but I didn’t like how Halfling felt as the name of an alien species and I was pretty satisfied with how many other species I had already)
