From the introduction:
You have been selected for a very important expedition to the lost continent of Azlant! After hearing of the expedition, you applied for adventure, and those responsible for organizing the expedition selected you to join other colonists to stake claim to an island named Ancorato in the Arcadian Ocean.
The Ruins of Azlant Adventure Path begins with your characters standing on the deck of a ship after a long voyage to a newly founded colony called Talmandor’s Bounty on an island in what is left of Azlant. The journey from Almas in Andoran to the island of Ancorato has taken 6 weeks aboard a ship called the Peregrine, and you and the other PCs have had a chance to get to know some of the other colonists.
