The Katachton Mountains, which serve as a shield between Akros and the rest of Theros:
- The Court of Orestes, which lies along the Khystonos River.
- The Khystonos River, whose headwaters reside in the mountains.
- 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.
- 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 anvil-wrought creature into the world or burst wide, unleashing some manifestation of Purphoros's fury.
- 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.
- The Pool of Lyth is a great rock outcropping that looks vaguely like a satyr's face. The stones weep a steady flow of water, which spreads into a serene, sky-blue pond. Said to grant visions of the drinker's greatest desires, the pond is filled with a poison of Pharika and guarded by harpies. Willows grow along the pond's shore.
- Shrine Peak, a mountain shrine to Keranos.
