What is "yalain"

The Yalain have been proposed as a Maya polity that existed during the Postclassic period (c. AD 1000–1697) in the Petén Basin of northern Guatemala, based in the central Petén lakes region. A small town called Yalain was described in 1696 by the Franciscan friar Andrés de Avendaño y Loyola. It was said to consist of a relatively small number of residences clustered within rich agricultural land. The town was located to the east of Lake Petén Itzá and was said to have been farmed by the inhabitants of Nojpetén, the capital city of the Itza kingdom. The political extent and archaeology of the Yalain is poorly understood.
