Sands of Aura is an open-world action RPG set in the sand-buried realm of Talamhel. The world was plunged into ruin by a tormented god, shattering time and creating an endless desert populated by corrupted husks. Players assume the role of a Remnant Knight, tasked with confronting an emergent evil and protecting the remnants of humanity. Exploration occurs across sandseas on a customizable grainwake ship, with no explicit map markers guiding the player.

The game features souls-like combat, emphasizing challenging encounters against corrupted foes. Players can craft thousands of unique weapons by combining hundreds of weapon components and can choose from seven distinct fighting styles. Augmenting combat capabilities are dozens of armor sets and magical modifications. A settlement-building mechanic called Starspire allows players to shelter refugees, with choices regarding these individuals impacting the story and granting perks. An undead companion can accompany the player on their voyages.
