Tjececcele Houmn is a custom race I once made for my Astral Sea DnD campaign. They behave much like insectoids and have a tight knit community with their members being mostly females, with few precious drones. The queen and her nearest would govern the fun loving populace in sections of the hive each. Any Female Houm have the abillity to branch off to make their own hive, given a single drone goes with. As they live in the astral sea, part of "space" in Atia - They live as mostly merchants, diplomats and mercenaries, as they are usually charismatic, mercantile and strong of body so these jobs suit them very well.

Most importantly, for other races who do trade with the Houm eagerly, is their abillity to secrete diamonds as a byproduct of their biological needs for eating meats, rocks and exotic spices. Naturally, many spells in Atia (and DnD in general) requires Diamond to cast - As such the Houm are also very careful to expose themselves to their many greedy enemies. They can also survive the vacuum of space for a considerble amount of time, some can hold their breath for upwards of six hours.

I've not tried to do these as a playable race, but it could go something like this:

+2 CON
+1 CHR

Resistant to Cold.
Proffecientcy in Perception and a choice of either Persuation or Deception.

If well fed, You can secrete Diamonds worth your total level times 10 (gold) - Once per week.

Quadruped: Strong build and Advantage against knockdowns or pushes.
Breath control; You can hold your breath for up to 2 hours. When you reach 9th level, you can hold your breath for 6 hours.
