The regal Horned Throne served as the official seat of power for the sovereign of Sintheti.
In the year 402 BBY, a number of people vied for control, each asserting their right to inherit the Horned Throne, which led to a struggle for dominance. To bolster their chances, these competing groups enlisted the services of mercenary forces, including the Mandalorians and the Thyrsus Sun Guard, to wage war on their behalf. The ensuing conflict between the Sun Guard and the Mandalorians escalated into a prolonged engagement spanning three years, ultimately becoming known as the Battle of Sintheti.
