Mesos in Owlboy: Location Guide
Mesos explained for Owlboy players: where this area is, what it contains, and how it fits between the game's regions.
What is Mesos in Owlboy?
Mesos is the highest area Otus can reach without a rocket or the Relics, and the party has to find a way up above it. According to the community wiki's Mesos page, the air there is too thin to fly any higher by normal means, which is why it marks the ceiling of ordinary exploration. It is mainly covered in snow and ice, and the wiki notes it used to be much warmer.
Where is Mesos in the world?
Mesos sits at the top of the world as players know it, above the regions below. According to the community wiki's Bonfire page, even the pirate ships will struggle to get past Mesos, so it is a natural barrier rather than a busy stopover. The community wiki's Mesos page describes it as the highest area accessible without a rocket or the Relics.
Who lives in Mesos?
Very few people live there permanently. According to the community wiki's Mesos page, the only permanent inhabitants appear to be Pa and Roland, who are Twig's father and brother. The same page says Twig himself used to live there but left, and the community wiki's Twig page adds that before the Pirates and Otus, Twig lived in Mesos with his brother and father.
How do you get past Mesos?
You cannot simply fly higher; you need special transport. According to the community wiki's Otus page, the scientist Kernelle provides a means to reach the islands beyond Mesos, namely a rocket. The Bonfire page records the party's goal at this point as needing to find a way up above Mesos.
Is there a secret tied to Mesos?
Yes — the community wiki links Mesos to an achievement secret. According to its Achievements page, completing a song unlocks an achievement, and collecting the key and bringing it to Mesos will unlock a secret. The page does not spell out what the secret is, so treat the reward itself as undocumented.
Is Mesos playable on Steam Deck?
Yes, Valve rates Owlboy as Verified on Steam Deck. Valve's test results list the default controller configuration as fully functional, on-screen controller icons matching the Deck, legible interface text and good performance on default graphics settings; external controllers are not supported for the primary player. The game is a single-player experience and is available on the Steam store.
