The Eastern Continent of the planet Caladan was the least populated of the three land masses of the world, and even less developed than the Southern Continent. The Western Continent was home to Cala City, the capital of Caladan, and the base of House Atreides.
The Eastern Continent had virtually no major cities of populace, and was mainly home to native tribes of Caladan primitives. It was also home to the Abbey of the Sisters of Isolation, a group of women dedicated to the simpler ways of life, which later became the exile home of Lady Helena Atreides.
Some of the natural resources native to the Eastern Continent were pundi rice and eels. Far off the northwestern coasts of the continent were the lairs of the fabled Caladanian Elecrans, a type of seawater electrical ocean-living creature.
