The clash at Sintheti, occurring in 402 BBY, is remembered because both sides enlisted the services of Mandalorian and Sun Guard mercenaries.
This battle prolonged the long-standing animosity between the two warrior factions, originating from a dispute concerning the Horned Throne on the planet. Competing individuals vying for the throne each employed one of the mercenary groups. Most of the combat unfolded inside the planet's catacombs and rugged terrain. This struggle spanned more than three years, beginning in 402 BBY and concluding in either late 399 BBY or early 398 BBY.
