Requiem for the Conqueror is a science fiction novel by American writer W. Michael Gear.

Set in a future when humanity has forgotten its origins in earth, the novel describes the political equations and power struggle between the emperor, a quasireligious group, a pre-sentient computer named the MagComm and the Lord Commander.

Humanity is trapped in a "gravity well", the so-called Forbidden Borders and there is increasing conflict because of ever-decreasing space resources.

He is separated from his soldiers and falls into the hands of a slave trader but escapes, and comes into contact with a quasi-religious group led by the magister (who in turn is advised by the MagComm).

The magister (under the guidance of the MagComm) believes that the Lord Commander is the root of all evil and attempts to assassinate him.
