The Twins, known as the Yunkut in the Sith language,[1] was the collective name given to a pair of asteroid fields in the Mure system that orbited Mure Prime at the L4 and L5 Lagrangian points of Mure's orbit. They were composed of the asteroid remnants of the other four worlds believed to have existed in the system prior to its prehistoric brush with the Galactic Center supermassive black hole, an encounter responsible for propelling the system out of the Deep Core at an angle perpendicular to the galactic plane. Though typically referenced collectively, the L4 asteroids were individually known as the "Ashes" and the L5 asteroids the "Tears."
Murese Sith and Rakata researchers theorized that the Twins may have been partially assembled at their respective Lagrangian points by the Celestials and their Killik client species. The Twins were posited to have served as a pair of "floating quarries" providing raw silicate rocky material for use in the 50,000 BBY reconstruction of Mure. Rocks contained in these fields were believed to have been moved via Celestial repulsor tractors to Lagrangian points L1 and L2 as needed, kept in close orbit before being fed to Mure's gravity well and maneuvered into place by Celestial astroengineering engines. The hypothesis that Mure's mantle and crust were composed of the rocky remnants of the other four worlds was corroborated by similarities between the modal magnesium oxide to iron(II) oxide ratios (defined as MgO / (MgO + FeO)[2]) and titanium isotope ratios (defined as 50Ti/47Ti[3]) of the Twins' asteroids and Mure's mantle and crust. The near-identical compositions thereof indicated that Mure shared a close chemical profile with the Twins and was likely built from its asteroids' rock content.[4][5]
