For the Lekgolo's unauthorized contact with Forerunner relics, the Hierarchs of the Covenant ordered the extermination of the species. The Covenant arrived in the Svir system with the intent to harvest the trove of Forerunner relics orbiting Te, but were appalled to find that the Lekgolo had nearly completely devoured the rings. In 784 BCE Te became the first world home to a sapient species discovered by the Covenant since the empire's formation. In 789 BCE, a Luminary led the Covenant to Te, the gas giant being relatively close to the Sangheili's native Urs system. Many of these Lekgolo fed on the Forerunner alloys and had eventually demolished the constructs almost completely.

Despite this impediment, the Lekgolo managed to venture to Te's orbit and colonized several Forerunner installations there a number of millennia before their contact with the Covenant. Īfter the firing of the Halo Array, the Lekgolo were able to develop Tier 3 technology on their own, although the Lekgolo's development of space travel was severely hampered by Te's high gravity. At some point, the Forerunners took the Thanolekgolo forms off of Te and used them in a failed plan to defeat the Flood. The orbital platforms formed a ring around Te and these installations would later be known as the "Rings of Te". The Forerunners once had a presence on Te and constructed platforms in orbit around the planet at this time the Lekgolo had not yet evolved into sapience.
