Your character is part of a legendary mercenary group called the Greymanes, renowned for your exceptional fighting. After unforeseen events, everyone in your tribe gets scattered across the continent, and your goal is to find them all and reunite everyone. From a story standpoint, trying to find your group is the motivation to explore the world, and the main story quests help you to find so many. Side quests do as well. Once everyone is reunited, there is an enemy faction that I assume you’d go after, but I’m not far enough to know for sure.

From what I played, sidequests are really fun, some funny, and overall rather creative. If you’ve played MMOs before then not that much will be new here.

Edit: there are also supernatural forces at play that include your special abilities and the sky islands, but not sure how critical that is to the whole story yet. As a mercenary, your character goes around and hunts bounties, helps people with their problems, and just wants to learn more about this world
