Does having a nascent Warp Storm throw your ship off course twice, prevent reliable long-range astropathy, turn into a full-blown Warp Storm to cut off the entire region from the rest of the Expanse, then accidentally stumbling into a Warp Portal into another Warp Storm count?
I mean, it's not a tactical "terrain" type of thing.
Other bits of stellar phenomena we encountered:
- A remnant nebula with only "rivers" of charged particles and various gases floating like ribbons
- A gas giant with an enormous gravitic pull, crushing its own moons and making translations difficult (to say the least). The detritus is forming a disc of crap around it.
- A planet that will hurl macroshells at you if you stray too far from the "safe zone".
- A system with only three-to-five channels in and out of the core worlds. Asteroids, comets, strong gravitic riptides, makes this a pirate's paradise--and it was, once.
- A cloud of comets flying in formation, containing precious xenotech inside, routinely sending chunks of ice at anything that gets close.
I think we've all encountered some strange, physics-defying, phenomena out there.
