This came was set in a world where super-powered humans started appearing one day in 1998, and is set in the year 2008. This game is a part of the greater Trinity Universe timeline, and is chronologically situated 90 years post Adventure!, White Wolf’s Pulp era game, and over a century before the psionic escapades of Trinity/Aeon. In this game, the players’ meta-human characters fit into a mundane world when they are not mundane, and the mundane populace react to the sudden emergence of novas.
