The Horizon has broken. The Axis has shattered.

Welcome to Aethel-Hearth - a world torn into floating vertical tiers. The old animals are gone, replaced by volatile Elemental Echoes who have forgotten their bonds with humanity.

You are a Field Researcher. Your weapon is not a sword, but the copper-wired Codex. Leave Hearth Town, fight wild spirits in real-time combat, earn their trust, and bring eggs back to the Hatchery. Gather herbs, ore, and fish; cook, brew, and smith at town stations; breed rare bloodlines in the Kennel; and chart the tiers until the Codex is complete.

• Real-time field combat - dual timers, three abilities, elemental matchups, meals and restoratives

• Catch and catalog hundreds of spirits — duplicates shatter to Embers; new species advance your Bonding research

• Hatchery, Kennel, and Pet Bank — warm eggs, run breeding unions, build your roster

• Eight trainer skills - cooking, herbalism, fishing, mining, breeding, bonding, smithing, alchemy

• Town progression - unlock station tiers, master recipes, and late-game legendary breeding chains

• Personal journal and field archive — story beats unlock as you explore

• Music-only audio by design — no gameplay sound effects

• Single-player - progress saves locally & Saves sync through Steam Cloud when you have Steam Cloud enabled for this game.

Primal Axis is built to be finished. The intended end is Grand Horizon at a full Codex — roughly months of comfortable play, not a live-service treadmill. No daily rewards, no seasons, no post-cap grind bar.

The full game requires a new save. Not compatible with the free demo.
