Amasa

Amasa, known to the Covenant as Alay'oso, is a human Outer Colony in the Grenadi sector, governed by the Unified Earth Government.

Rise of humanity
Amasa was colonized by humanity in 2467.

Human-Covenant War
In March 2526, Amasa was the tenth human colony in line to be targeted and attacked by the Covenant's Fleet of Inexorable Obedience, commanded by Fleetmaster Nizat 'Kvarosee.

While the Covenant fleet was glassing Etalan, a unit of the Silent Shadow, led by First Blade Tel 'Szatulai, arrived on Amasa to take a measure of the colony's defenses and search for hints of Forerunner artifacts. Aware that Amasa would be targeted by the Covenant, the United Rebel Front deployed a messenger to the world who located the Silent Shadow and delivered a transmission, before being slain by the Sangheili warriors. The transmission contained a message from Major General Harper Garvin, who proposed an alliance between the Covenant and URF to topple the Unified Earth Government. The Silent Shadow delivered the message to 'Kvarosee over Etalan, who sought to use the alliance as an opportunity to locate more human colonies. Amasa's status following the war is unknown.
