Tamar Rising
Silence falls across the former Clan Jade Falcon Occupation Zone as its warriors disappear, leaving a power vacuum in Lyran space. Former Clan citizens face an uncertain future, an Arcturan general challenges Tharkad’s rule, a Clan turns to conquest, and a mercenary seeks vengeance. This BattleTech sourcebook covers events in the region from 3151 to mid-3152, with a historical overview, profiles of key personalities and units, and game information for tabletop play.
