Sutëir, The Source of Negative Energy

The Sutëir's Rune is Entropy, it's Material Cryptstone, and it's portent 'Death'. Like all of the Themes, it has a holy Rune, named the Guardian who protects, or the Theme's consciousness. Sutëir's holy Rune is The End.
Erinion and the elves who worship the Themes, name Azure as the consciousness of Sutëir, separate but connected to Sutëir itself. Azure is the god of Falls and Ends. Reivanta and the men who follow the Guardian Faith name Father Verti as the Guardian against Sutëir. Father Verti is the god of Psychopompy.
The Convergence and Divergence Days for the Sutëir are flipped in the mannish and elvish understandings. The 31st of December, named the Last Day, is referred to as Convergent by the Elves, and Divergence by the Men, while the 30th of June is Divergent by the Elves and Convergent by the Men. This is due to their religious beliefs.
On the Last Day, people all across Sartova are fatigued, dead will rise as undead, and necromancers have great power. On the 30th of June, dying is more difficult, but not impossible.
