R. Abiad

Abiad was a member of the UNSC Navy and a crewmember on the. He was present for the Battle of Installation 04 in September 2552.

Installation 04
During the boarding of the Autumn, Abiad escaped on Kilo Tango Victor 17 with some fellow naval personnel: William Michael Lovell, Aki Hikowa, Singh, Wang, and Ellen Dowski, as well as their Commanding Officer, Captain Jacob Keyes. Also accompanying them were a handful of marines led by Corporal Wilkins.

The group was chased by elite Covenant troops, but whenever the group got cornered (and they did get cornered several times) Wilkins and his marines would kill enough Covenant troops to enable them to escape. Ellen Dowski quickly grew tired of this an loudly stated that the group should surrender. The group quickly became fed up with her rants and tied her up, leaving her for the Covenant while they left in order to evade incoming Covenant. The Covenant quickly found the incapacitated Dowski, and she informed them of the group's destination.

Death
After Dowski told the Covenant where the group was going, the Covenant were able to quickly surround the group and force them to surrender. This led to the execution of everyone in the group save for Keyes. Abiad was shot in the face by an Elite Minor carrying a Plasma pistol.
