Katachthon Mountains

While folk wisdom holds that the eastern Oraniad Mountains are blessed by the gods, dark, older magic supposedly holds sway in the Katachthons. While the Katachthons are a smaller range than the Oraniads, they are harsher and more volcanically active, with regular avalanches, storms, and unpredictable microclimates. Clouds obscure heavenly signs, guides become disoriented, and explorers wander in ever-smaller circles. And above it all, dragons rule the range-fire-belching creatures whose bellies, it is said, are filled with the flames of Purphoros's forge.
Those who live in the foothills of the Katachthons are loath to acknowledge any tales of wondrous treasure or mysterious creatures to be found there, only repeating a warning to travelers: if you must cross them, keep to the passes. The two passes, One-Eyed Pass and the Cypress Gates, aren't safe, but they are generally considered less lethal than attempts to blaze one's own trail.

The Highlands of Akros

At the northern edge of the Highlands of Akros lies the great Polis of Akros. The surrounding highlands sustain the city, but most of the surrounding lands are dangerous. The Alamon soldiers spend most of their time patrolling Akros's outlying areas, centering their patrols around scattered outposts. These serve as staging grounds for Alamon and Lukos units to prepare as they venture out to raid or guard against monsters and invaders. Arable land is scarce and valuabe in the Highlands of Akros. Scattered across small plateaus and valleys in Akros are small serf communities that farm the land. Volcanic rifts, landslides, and venomous animals make travel dangerous for anyone who doesn't know the terrain, and visitors wishing to avoid suspicion from patrolling stratians would be wise to stick to the roads.

One-Eyed Pass

The northern gap in the Katachthon Mountains if famed and feared for its population of Cyclopses. These huge brutes are always hungry and attack any wanderer who fails to provide a better meal.

Cypress Gates

A natural gap between two mountains on the west side of the Sperche River provides access into the Nessian Wood from the east. Ancient Setessans carved an impenetrable fortress into the mountains to guard the pass.

Mount Velus

Visible from Akros, Mount Velus is an energetically active volcano. The fiery mountain serves as nothing less than Purphoros's home in the mortal world.
While the volcano has only erupted a few times since Akros's founding, those minor catastrophes were enough to demonstrate that a major eruption might destroy the entire region. Akroans regularly leave offerings at the foot of the volcano, and rigorously dissuade travelers from venturing up to the sacred peak, hoping to avert the great explosion they fear is coming.
While some adventurers have climbed to the volcano's caldera, met Purphoros, and lived, the god's anger isn't the only danger. A red dragon called Thraxes makes his home in the halls of Purphoros's first residence, which the god abandoned to create a larger and more ornate home deeper in the volcano. The dragon occasionally uses the old forge to craft his own creations, melting gold from his treasure hoard. He sometimes gives these creations to Purphoros as offerings. In exchange the god allows the dragon to stay in the volcano.
Purphoros's forge lies in the deepest part of Mount Velus, near a vast lava pool. The massive iron forge is surrounded by the finest ores, metals, and gems. Some of the greatest treasures Purphoros ever crafted are contained in the god's residence, a forge-palace warded by an enormous, gilded iron door. Occasionally these doors crack open, admitting a curious anvilwrought creature into the world, or burst wide, unleashing some manifestation of Purphoros's fury.

Mount Vesios

Mount Vesios, also known as the Little Sister, is a smaller volcano that resembles Mount Velus and erupts concurrently with Velus. A monastery on its western slope houses scholars and spellcasters who study the volcano, believing that through it, they might be able to control the eruptions of Mount Velus. Numerous oreads and Akroan flamespeakers offer their omens from the volcano's heights.
