The Ten Stonehearts, a shadowy group within the Interastral Peace Corporation (IPC), have captivated the imaginations of Honkai Star Rail players since their introduction.

Shrouded in mystery and wielding immense power, this group plays a crucial role in the game’s narrative. Who are these individuals? What are their motives? And what secrets do they hold?

This article delves into the Ten Stonehearts, providing comprehensive details on each member, their unique characteristics, and their voice actors in Honkai Star Rail.

Who are the Ten Stonehearts in Honkai Star Rail?

The Ten Stonehearts are a highly secretive, elite team within the IPC’s Strategic Investment Department. All 10 members are directly under the command of the department’s director, Diamond.

Handpicked by Diamond and granted unique artifacts called “Cornerstones,” the Stonehearts are a diverse group with varying backgrounds and responsibilities. They possess extraordinary abilities linked to Preservation, derived from the Cornerstones or Diamond’s powers as an Emanator of Preservation.

Officially titled “Non-Performing Asset Liquidation Specialists,” their true role extends far beyond this simple designation. They are instrumental in the IPC’s most critical and ambitious projects, such as eradicating the Swarm infestation, revitalizing Jarilo-VI, and salvaging memoria from deadworlds.

The Myriad Celestia trailer “Stoneheart’s Oath Ring: Both Ends of the Scale” offers insights into each member’s values and character traits as they deliberate on Aventurine’s punishment for destroying his Cornerstone.
