The Blue Domain is a strictly pacifist water city built on intellect, innovation, and medical purifying abilities. It boasts the highest population of Healers and the highest thread bond rate in the entire Second World. Defined by concentric rings of sparkling reservoirs, sunlit canals, and limestone bridges, this domain requires all weapons to be removed upon entry. Its crown jewel is the Library of Alexandria, a towering mahogany archive devoted exclusively to gathering all knowledge from the First World.
