Short answers, pulled from the story.
The Wari, also written Huari, were a Middle Horizon civilization that flourished in the south-central Andes and coastal area of modern-day Peru from about 500 to 1000 AD. At their height they formed the Wari Empire, covering much of the highlands and coast of modern Peru.
The Wari capital, called Wari, is located 11 kilometers north-east of the modern city of Ayacucho, Peru. Other major remnants include the Northern Wari ruins near Chiclayo, Cerro Baul in Moquegua, and Pikillaqta near Cuzco en route to Lake Titicaca.
The Wari did not appear to use written records and instead used a tool called khipu, or knot record. Although the khipu is most widely known for its use in Inca accounting, many scholars believe its earliest use as a recording tool happened among the Wari.
The Wari culture began to deteriorate around 800 AD as a result of centuries of drought. The city of Wari was dramatically depopulated by 1000 AD, and the collapse of the Wari state marks the beginning of the Late Intermediate Period.
The Wari are particularly known for their textiles, which were well-preserved in desert burials and include tapestries, hats, and tunics for high-ranking officials. Each tunic contains between six and nine miles of thread, and the Wari also produced sophisticated metalwork in silver, copper, and gold, along with polychrome ceramics.
The Wari worshipped the Staff god, a chief deity in many Andean cultures, with some of the oldest depictions appearing on Wari textiles and pottery urns over 3,000 years old. They practiced animal sacrifice, including a young camelid and thirty-two guinea pigs buried in a lineage house at Conchopata, and some scholars believe the Wari Staff god preceded the three Inca gods of Sun, Moon, and Thunder.
