The Lupaus Plains have a continental climate, with the east (near the lake) being the warmer and wetter areas. Summers are hot and dry, winters are cold with significant snow. Strong winds blow year-round. The land slopes downward toward the lake, but only gently. Very few trees grow on the plain, mostly in stream-beds and other sheltered areas.
The Horse Clans maintain a winter settlement at Pyhin and consider Talvi to be sacred. Neither of those locations are open to outsiders. In fact, non-Horse Clan people are not welcome within several days travel of those areas.
