Born Marcus Valgar in the year GSC: 842, Saint Valgar was a central figure in the early history of the Church of God. 

The son of poor farmers on the planet Midori in the corporate state of Cosmid, Marcus Valgar dreamed of escaping the monotonous grind of farm life.  He found it first in religion, having been raised in the Church of God, but having a powerful religious experience at the age of fifteen (likely the result of ongoing mind-control experiments by Cosmid), and then in travel on behalf of the Church as a missionary.

Valgar spent most of his adult life traveling the eastern rim of the Planetary League, spreading the faith on frontier worlds, and quelling the occasional heresy.  He traveled widely, spreading the Church of God from Midori to Gabriel, and beyond.

Valgar died in GSC 10,153, trying to make converts on Bonnard's End,  when he was attacked by the forces of the Engine of Negation.  Saint Valgar is remembered and venerated as a martyr by the Church of God.
