Sangheili (Non-native)


Ulgethon was a rocky world colonized by the Sangheili in the pre-Covenant era.[1][2]


Topography and climate[edit]

Ulgethon was a largely barren and dry world, covered in rocky crags and mountain ranges.[2][1]


Early history[edit]

Ulgethon was at one point visited by the Forerunners, who left technology and various structures hidden in its mountain ranges. Prior to 938 BCE, Ulgethon was colonized by the Sangheili, establishing at least one settlement amid the structures built by the Forerunners, whom they worshipped as gods.[3][2]

Conflict with the San'Shyuum[edit]

Main article: Desecration of Ulgethon

In 938 BCE, the San'Shyuum Reformists arrived on Ulgethon with their Dreadnought, the Anodyne Spirit. The keyship's Luminary had alerted the San'Shyuum of a repository of Forerunner relics hidden in an enormous mountain range on the seemingly uninhabited world. The first pioneer detachment dispatched to the mountains discovered that they were inhabited by the Sangheili. Their first contact with the saurian species proved to be tense, but constructive. The San'Shyuum attempted diplomacy with the Sangheili by sending a delegation to explain that they, too, revered Forerunner technology as holy.[2][3]

However, the two species had ideological differences regarding the treatment of Forerunner artifacts, with the Sangheili viewing the manipulation of their gods' technology as blasphemy and punishable by death.[3] When the Sangheili learned of the San'Shyuum's sacrilegious intent to excavate Ulgethon's sacred relics, they turned against the invaders. Led by Arbiter Vema 'Togad,[4] the Sangheili summarily executed the delegation, sending their corpses back to the Dreadnought.[1][3] What followed was a year long violent conflict that left the planet a charred husk littered with fallen warriors and shattered ships.[2][3] This event would effectively spark a decades-long war between the two species, known as the War of Beginnings.[2][5]
