Omegakron (1984) is the final scenario box for Lords of Creation. Two more were announced, but never published. The world is poorer for that.

The portal from the previous scenario dumps the players 200 years in the future, in post-nuclear holocaust Akron, Ohio (Akron, no surprise, was Moldvay’s adopted hometown — the box includes a pamphlet on the city’s history, even!). The players need to uncover the reason for the shift in the timestream that resulted in the nuclear event (spoiler: an evil Lord of Creation is to blame). The climax of the scenario involves helping the ghost of John Brown lead a revolt among the wage slaves of Novos Akros against the hypercapitalist Managers. It is…kind of awesome?
