Sara, a former combat ai in the employ of the UNSC retired Sergent major HLM (hey thats me :P) was exposed to a EMP which fried most of her systems, leaving her completely disabled and was afterwards decommissioned and presumed destroyed as per cole protocol. but thanks to some quick talking and a bit of help from some friends in high places, HLM recovered his ai companion and went to work rebuilding her. and giving her very human like shell.
Sara is now classified as an android and is HLM's personal assistant. taking odd contractor jobs, helping out at home... or even in bed ;) her body is made from custom nerves and skin made from the cloning tech oni used and is very much eager to serve. she's also quite the audiophile listening and dancing to music... even when she thinks no ones watching.
