Siren Sea
The vast Siren Sea extends west from the known lands of Theros to the edge of the world. As Thassa's domain, the sea hides an amazing array of creatures, including the entire Triton civilization. Its legendary dangers range from deadly reefs and wandering islands to predatory beasts and devastating krakens. Ever-changing, the Siren Sea is a realm of impossible sights and constant danger, the setting of legendary odysseys and the crucible of heroes.
The Siren Sea is constantly changing. Many sailors have attempted to map the sea, and of those that have returned they have had vastly different findings. While many of the islands are well known and documented across many findings, their locations are what usually throw cartographers off, and any identifications or comparisons are to be made via descriptors of what the island has on it's land mass.
The Dakra Isles are the most well known set of islands in the Siren Sea.
