Era Digest: Golden Century (abbreviated ED: Golden Century or ED: GC) is the first installment in a series of PDF-exclusive products covering specific and significant time periods in the BattleTech universe's history. This Era Digest covers transitional time period in The Clans history, where OmniMechs are invented, Clan Mongoose is absorbed by Clan Smoke Jaguar, and technology progression from Star League technology to modern Clan grade technology.

The book also provides information for role-playing in this Era, with Character Modules for building and playing characters using A Time of War RPG system in this timeframe in the Kerensky Cluster and Pentagon Worlds of Clan Space.

Product Description[edit]


The Clans, brainchild of Nicholas Kerensky, emerged from the ashes of the decimated Star League Defense Force to create a new order in distant lands. Ritualizing combat, they established a new society where only the strongest warriors rule and justice is won through battle.

Ironically, it would be the death of the Clans’ founder that would catalyze this new society and spur a period of amazing technological and social growth known as the Golden Century. This was the age where Kerensky’s warriors and their descendants truly forged themselves into the powerful army that would one day return to the Inner Sphere in a righteous Crusade.

Era Digest: Golden Century is a mini-sourcebook that describes the development of the Clans at their origin in a new series format, giving players a glimpse of early Clan life, the basics of Clan rituals, and a look at the rise and fall of Clan Mongoose. Complete with rules and stats for several Golden Century units—including the first OmniMechs—Era Digest: Golden Century also features role-playing support for this crucial period in BattleTech history!
