Naval Battle Rules: The Seas of Cerilia

This supplement expands Birthright domain and War Card rules with sea travel, naval combat, and maritime trade. It covers sea movement, ship types, naval armament, sea trade routes, wind effects, and war magic, with maps of the waters around Cerilia. The set includes a rulebook, 51 naval War Cards for the vessels of Anuire, Khinasi, and Rjurik kingdoms, counters for crew capacity and ship movement, and a full-color battle mat for ship-to-ship combat. Sample navies provide guidelines for creating fleets suited to individual domains.
