Fort Venarium was an Aquilonian fort in Cimmeria. Aquilonia was trying to expand their empire, and started to invade Cimmeria. The Cimmerian clans were scattered and warring against each other, so the Cimmerian defenses were weak compared to their individual fighting strength. However, to defend themselves against the invading forces, the Cimmerians joined under one chief to fight against the Aquilonians. Together, the Cimmerians attacked Fort Venarium. This attack was known as one of the most brutal battles in the history of Hyboria. The Cimmerians slew all the Aquilonian soldiers, as well as their women and children. Aquilonia never again tried to invade Cimmeria.
