Everyone starts on the starter island. But as you level up, you unlock new locations, each with its own quests, bosses, and NPCs. If you’re ever unsure where to go, click your compass icon for your next location and follow the arrow to find it.
(Quick note: You’ll see players referring to the First Sea, Second Sea, and Third Sea. These are updates that each came with new islands to explore. You’ll start in the First Sea. And that is all we’ll be covering here today.)
