Shattered Isles¶
The Shattered Isles are the island fragment of broken Astia. Every list of what survived the Shattering names them beside South Astia, East Astia and Urastia (S387, S498, S372), and the Shattered Sea's few trade routes run "mostly from the Thyssal Empire to East Astia and the Shattered Isles" (S387). Beyond that, the archive is silent about the Isles themselves.
The Isles of Sorrow¶
The Isles of Sorrow are filed here until a source places them; the archive's folders put them under Astia and no closer. Among them lie the remains of "the Living Titan (an Earth-Water Titan)" whose "blood flowed into a river whose waters flowed over and through a gold deposit" (S417). The result is the best known deposit of red-gold Diaurumite Trioxide, the near-surface ore of Aurumite, the Mithis gold that is "in it's purest form ... deep blood-red" (S417). The Titans, living or dead, shape the land around them, and this one gave the Isles their metal.
A few lines of game arithmetic from a session on the Isles record iron smelted into Ferracite and slag fed to a volcano's Magma Forge (S453), so the Isles hold a volcano and a forge of that kind; see Mithis metals.
Gap
No source describes the Shattered Isles, their peoples or ports, or says in so many words that the Isles of Sorrow are among them.
