Beyond the mapped world, the Skythread sails into lands where memory, myth, and the living world collide.
Talon Silverbow, Arrabella, and the crew of the Skythread leave the familiar skys of Soahc behind and cross into the Orbis Ignotum-uncharted lands shaped by ancient migrations, shifting continents, and powers older than written history. Along the way they encounter Tortosian navigators sworn to protect their ancestral coasts, a dragon guiding a displaced people across wild and unclaimed lands, and the long-eroded bones of civilizations forgotten by almost everyone.
But their greatest discovery waits ahead.
At the far edge of the known world rises Dirgewood-a colossal tidal forest that moves with the sea. Each night, a haunting, wordless melody echoes from its shifting canopy. Sailors call it the Dirge. No chart explains it. No survivor has ever understood it.
And as the Skythread sails deeper into the living wilderness, the crew soon learns the song is not merely a warning... but a remembering.
To uncover the truth, Talon and Arrabella must navigate old wounds, buried histories, and a threat older than the Second Age itself. Their voyage will test not only their courage but their understanding of who they have become-and what the world is turning into.
Orbis Ignotum expands the geography, lore, and emotional heart of the series, exploring the cost of discovery and the fragile boundary between what is remembered and what is lost.
A voyage into the unknown.
A mystery carried by tides.
A world on the edge of waking.
