Monastic Tradition: Way of the Shadow Sun

From the introduction:

Monks of the Shadow Sun follow a philosophy of balance between light and darkness. They embrace rather than deny their own base impulses, exploring their inner demons and bringing them into the light. By accepting darkness as part of their soul, the monks of the Shadow Sun achieve a profound understanding of self. This allows them to harness dark energies to drain a foe’s life and convert that energy into light.
