Most lurkers are great sorcerers who have lived for millennia. Two powerful lurkers are the geneticist Ssruthaa and the high priest Ssathasaa. Dreamers are serpent people who escaped long ago to the Dreamlands. They fled to that land through the Vaults of Zin when Yig cursed Yoth long ago. Accordingly, most serpent people of the Dreamlands still worship Tsathoggua.
Sleepers are serpent people who have hibernated for thousands of years and are just awakening now.
They contend that the End Times are at hand, and that very soon they will found their third and final empire. Of all the serpent people, the sleepers are the most dangerous. They are extremely powerful, and do not remember the bitter defeats which swept their race so long ago. Although serpent people have poorly developed hearing, their other senses are very sharp. Their eye sight is very precise, and is particularly attuned to motion.
