Opus Operandi: Dark Side of the Sun
This adventure expands the Opus setting through an exploration of its history. It uses a nonlinear structure, allowing events and developments to unfold according to the campaign and requiring some improvisation to address different possibilities. It is the first entry in the Chronicle series, which focuses on historical aspects of the setting; other series explore its religions and locations.
