Stygia, The Primordial Chaos

The Stygian Rune is Chaos, it's Material Siccatite, and it's portent 'The Chariot'. Like all of the Themes, it has a holy Rune, named the Guardian who protects, or the Theme's consciousness. Stygia's holy Rune is Fabrication.
Erinion and the elves who worship the Themes, name Toriar as the consciousness of Stygia, separate but connected to Stygia itself. Toriar is the god of Civilization. Reivanta and the men who follow the Guardian Faith name Heivar as the Guardian against Styiga. Heivar is the god of Construction and Creation. The Dwarves, when they still lived in the mountain passages, had a single god, named Shaker Gekkar, who was said to have formed the dwarves from the stone like statues, then given them life.
On the 20th of Mar, Stygia is Convergent, great destruction and great construction are both possible. Fires burn higher, blizzards blow harder, and wonders are usually built on this day. On the 23rd of Sep, Stygia is Divergent, fires do not spread, blizzards and winds barely blow, rain is light.
