During the Covenant's massacre across the Outer Colonies, Falaknuma had very little UNSC Navy support, housing a base for a section of the Prowler Corps, as well as a handful of frigates led by Commander Arthur Resnick.
In 2535, Lieutenant Jacob Keyes escorted Habitat Exodus from the Rubble to this colony using UNSC Midsummer Night. The Exodus asteroid then disintegrated and its debris created a navigational hazard around the planet, which according to experts would take years to deorbit and burn up. Following the evacuation of the surviving Rubble population from Exodus, they were placed in refugee camps across Falaknuma, some of which quickly slipped away. Ignatio Delgado later enlisted in the UNSC Navy at a recruiting station in Halkia on Falaknuma.
On March 6, 2543, a minor engagement between a Sinaris-pattern heavy destroyer and Battle Group Sierra-3 took place in the 18 Scorpii system, where the UNSC Navy battle group was aided by insurrectionist forces.
The colony is likely named for Falaknuma Palace, a palace in Hyderabad, India.
