The loa were the supposed mythological gods of Faction Paradox. Unlike other gods, they occupied a plane of existence alongside humankind, rather than above it.

Faction Paradox often used the Loa as spiritual tools, summoning them so that the Loa would invest them with that Loa's particular abilities. Godfather Morlock was known to have summoned Loa out of thin air when he needed them. (PROSE: The Book of the War) Godfather Avatar was a loa, and was capable of riding a human psyche. (PROSE: Of the City of the Saved...)

From the perspective of the Great Houses, who saw history as a quantifiable string of equations, loa did not exist. However, Faction Paradox rebelled against this formulation by defining history as an ever-changing pattern, and just as shapes can be seen in clouds in the sky, the loa could be seen in time.

Particular loa protected the Eleven-Day Empire. (AUDIO: The Eleven Day Empire) Father Christèmas created a loa to protect Bankside by conducting an elaborate ritual involving the Chance Coteries.

Godmother Kumo wrote on loa evocation for The Book of the Truce, comparing stage-hypnosis to the Faction's use of ritual to appease, communicate, and bargain with the loa: as long as the volunteer is playing along (whether for fun, to avoid embarrassment, out of a sense of duty, or due to genuine hypnosis), the task will be performed, and the desired action will result.
