NPCThe giant rings on this planet's surface can be observed even from orbit.
YOUExamine the rings.
NPCIt has emerged that this planet has a native species of giant insect similar to Terran ants. Just like ants, they sometimes form so-called death spirals, in which one creature follows another without realising they're going in circles. These were the rings discovered by the ship's observers. The strange phenomenon that was originally suspected to be a sign of warp activity or a nefarious xenos structure turned out to be a quirk of nature, and a tragic one at that.
