Why did the ships go back to Aeolia?

The ships returned to Aeolia because they had initially received favorable winds from Aeolus, the god of the winds, which helped them set sail. However, after the crew opened a bag containing the winds that Aeolus had given them, they were blown off course and faced a storm that led them back to Aeolia. Upon their return, they sought assistance from Aeolus once more, hoping for help to continue their journey home.
