On a wild coast, a seafaring mage gets ready to dive to a magical pearl bed in search of a pearl of power. Meanwhile, a dragon tamer travels to Blood Isle to find an ancient dragon.

Res Arcana: Perlae Imperii, the second expansion for Res Arcana, introduces a new essence type — pearls — to aid mages in creating powerful artifacts in their quest for mystical domination. As their purity is coveted by all, pearls of power add versatility to existing strategies and open up new paths to victory.
