Obsidian Circle

The are a Sangheili terrorist organisation who oppose both the Swords of Sanghelios and the Covenant. Their goal is to force the Sangheili people to what they perceive as right path, to abandon false religions and twin weaknesses of honour and clan, and to embrace adherence to Sangheili superiority and adherence to the the Obsidian way. Considered to be a cult, they follow the goals and teachings of The Vizirache, their theological leader. They conduct terrorist attacks, assassinations, and raids against their enemies, sowing fear and terror. In the aftermath of the Great War, the Obsidian Chain has attracted significant numbers of disenfranchised Sangheili, enough to present a clear threat to existing galactic powers.
