Confluence is a sci fi/fantasy core rulebook and setting. The 9th Era of 14 that have existed over millions of years on a flat planet, Confluence sees elements of each of the worlds that came before and beyond it sliding through time to coexist. Extreme technologies clash with arcane magic, governments are fought over by bureaucrats from the 12th Era and the merchant guilds of the 8th.
Confluence is set to give a taste of all the future settings to be released by Cosmic Mirror Games. Each of those setting books will allow play groups to play in that setting alone, or use all the great new player options, races, items, and more in the Confluence core setting.
