Archaios

Throughout Riiga are a set of colossal prehistoric structures built by an ancient people or groups of people referred to as Manamorians. The ruins themselves are generally called high ruins or archaios in the west, or feixou in the east. Everything about the ruins, including their names, are given by the people who discovered them, primarily those in eastern Armalia, Ideitess, Umbener, and Nor. They are the largest structures in all of Riiga and are built mainly into cliffs or mountainsides. With the exclusion of Dalmuvar in Nor, they all show signs of significant and sudden damage, with huge solid stones seemingly blown apart by unknown forces. Erosion has also taken its toll on many ruins, though the way they treated their stone work seems to make it more resilient than what modern humans are capable of.

The builders of the archaios demonstrate a more advanced understanding of architecture and geometry than modern masters. They are all made of the same durable stone, all bearing the same patterns which don't match anything else in the world, and all show similar levels of decay, implying that they all come from around the same period. Some patterns, though very worn, are thought to depict unknown animals, suggesting that they were made in a time possibly hundreds of thousands of years in the past. The vastness and complexity of most of the ruins also implies that they could have been used as cities, able to house thousands of individuals.

Na Hangme

Na Hangme is located in the Valley of Life, at the western-most end of Ttudyqu. It has a long history with the Dunin people, who have used it as a sacred ritual site in the past, but have since declared it a place of great evil, as monsters seem to enjoy frequenting it in recent decades. Unlike the other temples, it is in a very dry, dusty environment, and has little in the way of plant growth to adorn its ancient surfaces. It is primarily built into either side of a canyon which has suffered a lot of collapse over time, so much of the archaios has become rubble in the valley itself. Architectural features suggest a bridge once connected the two sides of the valley, which would have been by far the largest stone bridge in the world, reaching around 300 meters (985 feet) across three arches above a river 120 meters (390 feet) below.
