Caladan

Caladan is a fictional planet featured in Frank Herbert's Dune series. It is the homeworld of House Atreides, a powerful noble family within the Imperium. Caladan is depicted as a water-rich planet, characterized by vast oceans, frequent storms, and a humid climate. This environment has shaped its inhabitants, who are often described as skilled sailors and warriors, accustomed to a harsh and unpredictable natural world. The planet's economy is based on fishing and its strategic importance stems from its location within the Imperium. Throughout the series, Caladan serves as the ancestral seat of House Atreides, representing their heritage and the life they are forced to leave behind when they are granted stewardship of the desert planet Arrakis. The transition from the watery Caladan to the arid Arrakis is a significant theme, highlighting the challenges and adaptations faced by the Atreides family.
