I was working on a potential adventure concept fitting a Spelljammer game. Being mostly a homebrewer, I wanted to invent my own, new spelljamming race and spelljamming ship. I created a cultured race of gnolls who worshipped Anubis in addition to the other Egyptian gods and called themselves the Gnolleans.
Instead of standard spelljammer wizards, the Gnolleans have necromancer pilots, because the primary vessels of the Gnollean Spelljamming Navy are colossal undead scarab beetles that inhabit a verdant moon orbiting the Gnollean homeworld. Because I previously created a 5 man huge version of the same undead beetle, I thought to imagine that the colossal version is kind of an aircraft carrier that could carry 3 of these 5 man versions to serve raiding squads from the larger mother ship. These ships are empty husks of colossal dead beetles with intact wings to aid in sailing the phlostogin, that could also be used for aerial flight into the atmosphere of a crystal sphere - and with beetles legs can walk as armored weapons platforms and troop carriers making them a very dangerous force in their part of the Spelljamming universe. Unlike the open decks of other spelljamming races, the Gnollean Scarabs have protective beetle abdominal exoskeleton shells that cover the deck for a more defensible ship.
Also, since I imagined the Gnollean race to be influenced by the Egyptians, I even created their capital city of Anubia, not the Anubis stylized sphinx near the center of the city map, south of the pyramind. Like gnolls and Egyptians, Gnolleans are militant slavers under god-priest-king pharoahs.
Don't know if you can use any of this for your game - since none of this content is official, just an up-in-coming spelljamming race of my invention.
