Saepon’kal[1] (translated: Joyous Exultation) was a Covenant colony. It was located in the fringe of the massive Covenant Empire in the Salia system and had a small moon, Malhiem.


During the Great Schism, the planet was a rally point for the seceding Sangheili, under the leadership of Imperial Admiral Xytan 'Jar Wattinree. The Combined Fleet of Righteous Purpose met here, along with several ships from the Second Fleet of Homogeneous Clarity as well as many other Sangheili-controlled vessels. They planned to set up a meeting with the Covenant Loyalists on this planet, where they would massacre the Jiralhanae and San'Shyuum leadership.

Unfortunately, the plan failed when a NOVA Bomb taken from Reach by the fleet's flagship, the CSO-class supercarrier Sublime Transcendence, was accidentally detonated, vaporizing a quarter of the world, shattering the planet's moon, and destroying much of the Swords of Sanghelios' fleet gathered there. However, due to the large size of the fleets, about a quarter of the vessels on the other side of the planet escaped. The bomb also caused massive shock waves that leveled many cities on other parts of the planet. In addition, the explosion resulted in 300 mile-per-hour winds that razed many of the remaining cities, and created massive tidal waves that destroyed much of the coastline.[2] Imperial Admiral Xytan 'Jar Wattinree was atomized by the blast.[3]

The Jiralhanae, knowing that Joyous Exultation would serve as an anchor point for the Separatist forces, intended to lay siege to the planet. By the time they arrived, however, both the planet and the fleet had been destroyed.[4]
