Obsidian

Last updated 2026-09-06

Obsidian is a rank P46 employee of the Strategic Investment Department in the Interastral Peace Corporation, and a member of the Ten Stonehearts.[2]

She makes her first appearance during Myriad Celestia Trailer: Stoneheart's Oath Ring: Both Ends of the Scale alongside her fellow Stonehearts.

Profile

Little is currently known about Obsidian, besides being one of the Ten Stonehearts and one of its four high-ranking members alongside Aventurine, Jade and Opal. Following her failed mission on Jarilo-VI and subsequent demotion, Topaz was allocated to a project on Penacony helmed by the then P45 Aventurine, which she believed should have been handled by a P46 or higher-ranked member like Obsidian or Opal.[3]

Obsidian has shown several predatory and sadistic behaviors. After the Silverchain Galaxy had been officially included in the IPC's commercial sphere, when Opal commented that the galaxy should've just been destroyed by an ion storm, Obsidian replied that there was no fun in prey that die a natural death.[2] During the meeting to decide Aventurine's expulsion from the Ten Stonehearts, Obsidian voted on behalf of Agate and herself to expel Aventurine, stating that they were being overly timid, preferring a "bloodbath". She has been seen enjoying blood red wine on at least two occasions.[4]

Like other members of the Ten Stonehearts, Obsidian is in possession of her own Cornerstone, an extension of Diamond's power as an Emanator of Preservation.[5][6]
