For most of my life, I made a big worldbuilding project for a bunch of star systems located near the galactic core. Looking back it was barely hard sci fi with wormholes and a bunch of alien chemistries that are probably impossible. I think i'll introduce a few characters from that into OA at some point (adapted into physically possible neogen clades, or something).
I think my favorite idea from that set of worldbuilding stories was probably the 'world trees' that had colonized the entire region/ galaxy. They existed mainly as immense organic space-and planet dwelling trees 1-5 km tall. They were 'poly-multicelled' organisms, which meant they were essentially immense fused ecologies- usually tree shaped that somehow managed to grow into spacecraft. They were supposed to have some vast alien collective intelligence (similar to the planet solaris by stanislaw lem) and grew huge magastructures.
Fun times.
The other big worldbuilding story i've done (am still making?) is a giant fantasy world/ universe based mostly on new age mythology- with crystal space dragons and 'innerspace' rather than outer space. Characters traveled to innerspace through a type of elaborate astral projection into the dreamworld, which had multiple levels, (dream within a dream). I've got a bunch of half finished stories, but it's probably still best represented through images- basically, if a Tool music video became a space opera.
