The Trinitine is the major religion of the Exarchates. To be a Trinitine is to believe in three gods:
Observe Cold Light, the god that separates inky firmament and the wanderings of its stars, such that Truth may be known.
Fear Varda, the chaotic unity from which all things flow downward. It is creation and destruction, the regurgitator and eater of infinite maddening things.
Worship The Ilmatian, Flesh-Born god of sacrifice. A man born of Varda (as all things are), but discoverer of Truth. Live as he did and produce Truth without doubt or falter.
