Lekgolo

Summary
The Lekgolo (Latin Ophis congregatio ) are a species of small colonial wormlike creatures that can join together to form purpose specific assemblages, such as Mgalekgolo

Mgalekgolo are commonly referred to by Humans as Hunters. The cores of Scarabs are also seemingly made up of Lekgolo worms.

Every worm-like creature is an individual eel about 1.4 meters long, with its own neural central system

These worms isolated Mendicant Bias from the rest of the Forerunner Dreadnought when it tried unsuccessfuly to escape from High Charity

See Mgalekgolo for more information on Lekgolo assemblages.

History
The Lekgolo evolved on their homeworld of Te and fed by burrowing through the earth of their planet. They came into contact with the Covenant when the alien collective landed in search of Forerunner artifacts.

They found only the remains of a space station which had once contained many artifacts, but was now bare due to the actions of the worms, which broke down and ate the devices. The Prophets viewed this as heresy, and declared war on the Lekgolo in what would later be called the Taming of the Hunters.

With the aid of an Arbiter, the Covenant were victorious and absorbed the defeated worms into their ranks. Groups of the aliens were given thick armour plates and Fuel Rod Cannons to help them serve the Covenant as Mgalekgolo. With the Covenant Civil War, the species was divided into those that supported the Covenant Loyalists and the Covenant Separatists.

The species's fate after the events of Halo 3 is unknown, although it is assumed that Te was not affected by the war.

Trivia

 * "Lekgolo" is Tswana for "one hundred", probably a reference to their hive-like physiology.
 * Lekgolo blood smells like burnt plastic.
 * It has been claimed that Lekgolo worms have been seen in the vulnerable area of Scarabs have given rise to speculation that Lekgolo operate the heavy weapons platforms for the Covenant, though this has yet to be proven.
 * Ophis means snake. Congregatio means assembly, society, union. Translated it means "assembly of snakes", no doubt alluding to their physical structure.
 * Lekgolo stopped Mendicant Bias from taking off in the Forerunner Dreadnought by disconnecting it from the ships systems.
