Tiar-Shi Sphere

The Thar'shi Sphere is one of the larger historical Sangheili civilizations, born out of a large Sanghelios empire that arose out of the post-Skyfall times and the Wars of Iron and Blood. Once a prominent political entity and the rival to the Crimson League in the Urs system, the Thar'shi Sphere is now more splintered, though its cultural legacy lives on.

In its heyday, the Thar'shi Sphere was an industrial powerhouse, and more centralized than the Crimson League. They expanded their territory through conquest and later economic domination of smaller polities. They controlled sizable surface holdings on Sanghelios itself, though their territory on the homeworld was smaller than that of the Crimson League. In addition to this, the Thar'shi Sphere had invested considerably in off-world holdings throughout the Urs system and later beyond, expanding its influence throughout the Sunlit Worlds in the pre-Covenant era. Owing to its centralized nature, the Sphere was famed for having the largest and most standardized standing military at the time of the War of Beginnings, but this — combined with various cultural and political aspects — also made them less flexible.
