Overview
Xolterra is the expansive island west of Xalmyrra, across the western sea. Its essence is pink and golden-yellow, and the island is the origin of aether magic and resonance magic.
Xolterra's main political powers are Thalassai and the northern Tenari region of Thalcoris. Thalassai rules much of the island. After Cassian kills Meliora and destroys Xoh'Metztli's divine essence, Tazarin becomes Thalassai's archon of cosmos in Thalcoris.
Geography
Xolterra lies west of Xalmyrra across a fairly shallow ocean. Storms, barriers, and darkness long isolate Xalmyrra from Xolterra. Thalassai maps show Xolterra, nearby Xalmyrran regions, and the turbulent eastern storms together.
Thalcoris occupies northern Xolterra and includes dense jungle, Tequaltor, Aurivallis, Chalxata, and Xalatun. Thalassai includes Chronasis, Pyrenis, Terranova, Aetherion, and Thalmyris, and Chronasis is its capital. The southern reaches of Xolterra border darkness zones guarded by Thalassai forces, and the Thalassai navy can sail around the island as part of defense planning.
Xolterra belongs to Valrindor. Some regional maps omit both Xolterra and Xalmyrra.
Peoples and Magic
Xolterran peoples include descendants of Xalmyrrans who came through gates from Xalmyrra. Orin, Khoradyn, Therion, and Xandor are founders of Xolterran societies.
Xolterran mages often wield multiple schools. Thalcoris has especially strong aether and resonance traditions. Thalassai uses advanced magic in windweavers, watergliders, gates, research centers, legions, navy, and archon rule.
Xolterra also has distinctive wildlife. Enormous native birds fly above the jungles and savannas of Thalcoris.
History
The western island's earliest known atraxi settlement failed when Jorhan / Xol'Zahir took a spiral shard from a sealed vault on the island, gained overwhelming power, and unleashed a wave of pink and yellow essence that killed atraxi settlers. The survivors fled back to Xalmyrra, and Jorhan returned changed.
After Jorhan defeats Aldred, Xalmyrran refugees escaped through gates toward the western island. Xelthys guided survivors there; Orin later founded Thalassai, Khoradyn founded Thalmyris, Therion founded Thalcoris and Tequaltor, and Xandor founded Aurivallis. The AX/BX year count begins with the first settlers in Xolterra.
For millennia, Xolterra remains divided between Thalassai's archon-led society and Thalcoris's Tenari order. Thalassai develops regional archons, legions, a navy, research centers, windweavers, watergliders, and gates. Thalcoris lives under the Tenari false war, where Xoh'Metztli controls Tenari minds with resonance magic and feeds essence to Xol'Zahir through deaths around Xalatun and the essence towers.
The Tenari false war ends when Cassian kills Meliora and destroys Xoh'Metztli's divine essence in Aurivallis. The Tenari are freed, Thalcoris begins rebuilding, and Tazarin later becomes Thalassai's archon of cosmos.
After the coalition attack on Thalassai, Ozaith tries to force Thalassai to submit and summons an asteroid large enough to annihilate Xolterra. Thalassai survives, Ozaith is destroyed, and Thalassai's armies and gates carry Xolterran forces against Zain in Solvarria and Pyrenis, against Raphael around Cyndarel, and toward Zarephon and the source.
