Caladan remained under the rule of House Atreides, with Paul’s mother, Lady Jessica, taking over as regent. The planet continued to prosper and maintain its oceanic culture.
When House Atreides was granted stewardship of Arrakis, also known as Dune, they left their ancestral home of Caladan. However, Caladan did not fall into disrepair or chaos. Instead, it remained an important part of the Atreides’ holdings. Lady Jessica, the Bene Gesserit concubine of Duke Leto Atreides and mother to Paul Atreides, returned to Caladan after the events on Arrakis unfolded. She became the regent, ruling in the stead of her grandchildren, Leto II and Ghanima, who were on Arrakis.
Under Jessica’s leadership, Caladan continued to thrive. The planet was known for its lush, verdant landscapes and vast oceans, and it maintained its reputation as a place of learning and culture. The Atreides’ ancestral seat remained a symbol of the family’s enduring legacy and their commitment to justice and good governance. The people of Caladan remained loyal to House Atreides, and the planet continued to play a role in the larger political and economic structures of the Imperium. Caladan’s stability was a testament to the strong leadership and the deep roots that House Atreides had established on the planet over many generations.
