Aether is the origin of all energy in Ruachland. Driven by Aether, nature evolves, life sprouts, and wisdom condenses into spells. In Pennon and Battle we designed two factions skilled in Aether—the Elven Empire and the Eternight Council. In the study of Aether spells, Eternight Council and Elven Empire took different paths: The Council leans towards Aether craftsmanship, wielding alchemical creations in their spells; while the Elves are closer to nature, understanding the essence of Aether more deeply. When the Elves touched upon the ultimate secrets of Aether, greed and desire birthed a dark entity, an Aether Eclipse. It rose abruptly, devouring thirty of the continent's top Elfspell masters and an entire city, becoming a nexus of negative energy. Then, this Eclipse silently fell. The eternal darkness was sealed and transformed by the Eternight Council, given form and spirit, becoming the most loyal among the many immortality seekers of the Eternight Council: the Darkness Herald.
