The Knot in the Verse
Prior to The Invasion, the people of Berisole would go to sleep at night and spend their time in oblivion. Virtually nobody dreamed. Those that did, The Dreamers, were alternatively worshiped and despised.
Members of The Army dream normally, and the Kalashtar among their numbers are actually an active part of the world of dreams. Many among the indigenous people of The Continent are in awe of The Army for this ability.
