As night falls the Toskals deity rises, a great guardian spirit that protects and lights the way when vengeful spirits with their glowing eyes appear. - The Moon
Many of the swamps inhabitants have highly reflective eyes like the Toskals, leading to their deep seated belief that the spirits of the dead possess the animals of the swamp, sometimes watching, sometimes to get revenge. Either way it's advised not to wander alone at night. The moon lights up the land though, showing the hiding 'spirits' to any Toskals nearby and lending them courage.
Every month when the sky turns black (the new moon) an offering is presented of food and crafted items, this ensures that the moon spirit returns again.
~~~As the Toskal species spread over land and develops new religions arose, those that believe the Sun is all giving, those that choose to think the Earth itself holds true life, and some who believe it's the cover of Darkness that holds sway over the tribes~~~ (The main three extra that have sprung up from actual Toskal adopt owners)
