Most "civilized" orcs adopt the gods of the society into which they have integrated. But even they remember the Old Gods, who brought the orcish people out of darkness in time immemorial.
Domains: Darkness, Joy, Moon, Nobility, Renewal
It was under the soft light of The Silver Lady that orcs first saw color and knew respite from the horrors of before. Her rule of the night comforts her followers and inspires them to greatness. Like her waxing and waning, her people are ever-revitalized.
Domains: Animal, Earth, Planning, Plant, Water
When orcs came out of the darkness, they were not greeted with plenty. Instead, Keṃ demanded their toil, their suffering, and their perseverance before He would bear forth the fruits they needed to survive. Where Koṃ moves and burns and scours, Keṃ is silent, brooding, and withholding.
Domains: Fire, Fury, Strength, Sun, Wrath
Koṃ does not love; Koṃ only burns. Those who worship him, however, understand that the pain makes them stronger. Koṃ will not hold your hand in comfort, but will raise it aloft in victory.
Domains: Courage, Fate, Knowledge, Liberation, Magic
Swāñco is the son of Koṃ, and the god-hero who led the orcs above ground. Like his father, he brought pain and discomfort to the orcs of old who lived only in darkness. His presence would not allow them their customary complacency, but spurred them to act. Through his wisdom and magic he bought their salvation from underground, and ruled in the moonlight for a time as Chief.
