Lan-Zarek is a region in the south-central part of the MidLands. It is bordered on the west by the Vorilon and Adrilon Rivers, on the east by the Thair Mountains, on the south by Hanaellan, and on the north by Alior. Much of the region is in the Vorilon's basin, and much of the western part of the region is swampy, with its primary residents being lizard men and saurials. The northern part of the region is called Onyshire, and is home to a number of Halfling communities.
