Ilhuiyoco
Ilhuiyoco was the most prominent name of a longstanding civilization in the southwest of Altaia, prior to colonization efforts from Anaria. It was predominantly known for its Great Houses (mecayoh, singular mecayotl), its honouring of ancestral spirits, and its considerable technological advancement—at least, compared to much of the rest of the world, if not to Anaria. Remains of Ilhuiyocan culture, in the forms of architecture, traditions, and local languages, persist to this day across the south of Altaia, and in the writing system of Chaska.
