maybe in one wildspace system, the local lizardfolk had a fleet of incubation ships that orbit the sun closely to warm their eggs (because in #spelljammer a warmer egg makes a smarter lizard-guy).
but their incubation ships keep getting attacked by neogi slavers who want to steal their eggs and/or make lizard omelets.
so they hire some carp hengeyokai samurai as bonus guards, who chill in their water tank and spring into action if a neogi spider-ship approaches.
