+Fresh Basic E1/E2 Nexus starts now initialize native reactions when all
+selected families are seated. Harkonnen Use/Pass reaches the original Mentat

+games with Ix and CHOAM decks and Nexus alone enable printed and Nexus-fueled
+Kull by default, with host opt-out and the original Sandtrout. Ten related

+cards, positions and earned Nexus identities. Other module combinations,
