Somebody blew up a couple of drone chemical freighters leaving Rosmerta with loads of helium separator resins (check) for the AWSF. Pirates had made a threat but had been paid off by the shipping company and now deny responsibility. Figure out what happened. Also, the attacker had military-grade chemical engines made by the now-defunct rosmertine fleet yards.
People on Rosmerta are bitter about that, still.
Rosmertine Fleet yards is equatorial and has space elevators.
