The Canon of Shatterbridge is not totally egalitarian. Due to the advent of Eclipse, most material from the original game has been placed into a lower tier of canon. Material from these stories may be either used or discarded as subsequent writers see fit.
Primary Canon[]
This material is unambiguously canon, and may not be contradicted without good reason. Material in this tier includes Eclipse and Piero dala Vachio's story.
Good Reason[]
Dreams of Empire has started and with it canon has been revised again. Sorry.
