How to Fill in the Octopath Traveler 2 World Map by Reaching Lostseed

If you’re playing Octopath Traveler 2, you may see an obnoxious empty gap on your world map. You know what I’m talking about. There’s that landmass below New Delsta, and it seems impossible to reach. Well, the bad news is, you can’t get there right away like you can many places in the game. The good news is, all you need to do in order to unlock that part of the map and its town of Lostseed is go through Throne’s story in Octopath Traveler 2.

Throne’s story begins in the Brightlands Underground Waterway you can reach from New Delsta. There’s a locked door at the end of the path. It won’t unlock until you get keys from both Father and Mother in chapter three of her tale. Once you do, you can head to New Delsta to take part in chapter four. (This is a level 45-recommended quest.) After seeing the tombstone in the backstreets area that says “I await where it all began,” Throne heads to the entrance to the Underground Waterway and goes to that locked door at the end.

Opening it and walking through takes you to the danger level 45 Deserted Highroad. You can journey through this space, with a brief gondola ride, to get to the town of Lostseed in Octopath Traveler 2. Going through the town can also take you to the level 45 Lostseed Castle dungeon.

Simply reaching both places for the first time is enough to fill in those empty gaps in the Octopath Traveler 2 world map.

Octopath Traveler 2 is available for the Switch, PS4, PS5, and PC. A demo is available.
