A Resection of Time is a short campaign for Call of Cthulhu set in the modern day. It begins in early April, in San Francisco, and ends a little later in the steamy jungles of Belize, in Central America. Before plunging into the dark heart of the ancient Mayan world, the investigators also travel to Los Angeles and shadowy Arkham. The details of Mayan architecture, culture, epigraphy, and theology, as well as the experts on these topics named in the scenario, are all real, modified slightly where appropriate to incorporate the Mythos. Likewise, the places mentioned herein (save, of course, for the Sanboume Institute and Arkham), particularly the Belize locations, are real, although described for dramatic impact.
