There are two things meant by Light's Army. The first is as a byword for the religion of the Light, as prescribed by the prophet Dawncaller. The second refers to the specific, militant nascent polity based within the Temple City under Light's Heart.

Light's Army differs little from historical practice of the Light, largely because little is known of this practice before the Dawncaller. Of signal importance is still the practice of general kindness, an exultation of personal freedom combined with societal responsibility, and a strict belief in the rejoining or spoliage of the universal current of the Light upon death.

The deviations can be quickly summed up as follows:

• It is important for your soul to live among other followers of the Light in a holy nation, and be willing to take up arms in their defence.
