And the winner is —
Industrial (Produce): Consumer Suspensors (two votes plus tie-breaker)! Second was
Artistic (Workers): Traveling Companies (two votes), third was
Military (Produce): Small Arms (one vote).
Suggestions for both secondary domains are now being accepted!
Artistic (Workers): Traveling Companies could easily build off
Industrial (Produce): Consumer Suspensors if we re-imagine them as, say, sponsored suspensor-sports competitions rather than theatrical performers. Swoop racing and hoverboard leagues, anyone?
Had
Military (Produce): Small Arms won, you might have built off that as well with Military (Expertise): Weapons Trainers to truly be full-service arms dealers.
