Composer

The Composer was a Forerunner, or possibly a Forerunner machine, that could extract the personality and memories of a living being. It would do this for the purpose of creating an ancilla such as a monitor, or to integrate them into a geas as it did with the Lord of Admirals.

The Composer, or at least its handiwork, was present on Installation 07 around 100,000 B.C.E. It would later have a bearing on events within the shield world of Requiem in the year 2557.
