The Uncharted Continent is Geba's colossal eastern landmass, larger than all other continents combined by many magnitudes, a realm of extreme geological volatility with stratospheric peaks exceeding 60 km and shifting fissures. Coastal edges experience unexplained temperature extremes from 90 degrees below zero to 120 degrees Celsius within hours. The interior remains utterly unexplored. No permanent human presence has ever been established. Imperial doctrine forbids entry.
Titan-scale predators are known only from sightings in other regions. When pursued, they invariably flee toward the Uncharted. All navigation systems and electronics fail when approaching too close. Pilots call this the final warning to turn back before it is too late. Ioe Jerhit's failed expedition remains the only documented attempt where a team returned.
The Uncharted connects to the rest of the planet through more than coastline. Kela shares a direct land border to the north, and Saethera connects to the south. Deep in the interior of Inland Thazvaar, canyons are theorized to lead to the Uncharted through subterranean caverns, passages that no expedition has confirmed but that the geography and the behavior of creatures emerging from them strongly suggest. The Uncharted is Geba's final, absolute frontier.
