Ruwan Ackerson

Were you looking for Ruwan's brother, Colonel James Ackerson?

Ruwan Ackerson is a hotel concierge in Cleveland in 2552. He used to live in Mombasa, where he had a home and friends. Ruwan was not present when that city was destroyed, but he found himself caught in the midst of the Battle of Cleveland with Myras Tyla. He is seen driving an anachronistic American muscle car with Tyla through Cleveland.

He and Tyla were captured by the Covenant, who demanded from them the Key of Osanalan. Unbeknownst to the aliens the object was fictional; Ruwan and James Ackerson invented the object while playing in their childhood.

Ruwan and Tyla escaped their captors in a torn down Transport Warthog. After evading enemy patrols they were found by UNSC forces and evacuated by Pelican.

After informing his Pelican escorts about what he knew regarding the Key of Osanalan, he was taken to an underground base established by the Marines in the old sewers of Cleveland. There he met Sergeant Twyker and Intel Operations Manager Wesley.

Although initially hostile to the civilian, Twyker realized the significance of the fake key and with Wesley they devised a plan to use the knowledge to their advantage. They found a way to contact the Covenant and inform them that they had the key and to meet them for it. Ruwan volunteered to partake in their new mission despite the protests of Tyla, and was injected with an organic tracking material. He then was taken to the agreed upon meeting place at Chagrin Falls, Ohio where a Brute Chieftain demanded he give them the key. Ruwan hesitated, and then told them he was the key.

Confused by this development, the Brutes took the human onboard the Covenant Cruiser Harbinger of Piety to meet with the Prophet Minister of Inquisition. He questioned the human and promised to spare Earth in exchange for his knowledge. Ruwan played along until the Prophet informed the human he knew about the organic tracking material.

The Prophet believed Ruwan was using it as a rescue beacon. Ruwan was happy to inform the Prophet he was mistaken, that it was a targeting vector. With his last words he told the Prophet to "Kiss my ass" right before the Nassau Station used its MAC cannons to blow the Harbinger into oblivion.
