A view of the expansive ruins from atop Trico. The design was somewhat changed between this E3 2009 look and the final game, though the atmosphere and architectural style remained.

Though not much is known about the world in which The Last Guardian is set, much can be discerned from what remains of the crumbling ruins and from its respective geography.

The Nest


A place shrouded in mystery—and for good reason. The Nest is a massive, crater-like valley surrounded by sheer,impassable mountain walls that can only be by-passed by flight. Where the Nest truly gains its formidable and lonely atmosphere, however, is within its bowels; crumbling ruins, towers, courtyards, bridges, passageways and temples lay in relatively uninhabited decay.

On the outside, structures straddle deep caverns and any remaining pathways are often treacherous. On the inside, endless tunnels—some of them flooded—offer more puzzling situations.

The buildings and stonework are heavily overgrown by lush, green ivy, sections of forest, and other lesser plant life, such as moss and lichen. It is unknown who constructed these ruins, as well as who may have lived here before, or, what may have happened to cause their downfall. It is possible that the Master of The Valley was responsible for the Nest’s current dilapidation, although it is uncertain. 

The carvings and runes coating these ancient structures can offer us insight into the Nest’s history; their overall shape, style, and design highly resemble, if not match, those of the Master of The Valley. One theory is that these runes were implemented by the Master. If so, he might have been responsible for the ruins’ construction. Another theory is that the people who built the ruins happened to share a common language with the Master. In this case, the Master’s involvement is indiscernable.

As the ruins are uninhabited by any known civilization, animals and other beings have come here to take up residence. These creatures include Tricos—huge, winged, griffin-like beasts—as well as an army of possessed suits of armor called Armored KnightsThe most notable being of the Nest, however, is the Master of The Valley as he appears to assert dominance over the others. 

The only one of these inhabitants shown to be capable of leaving the Nest, save for wild birds, are the Trico beasts. This is probably a significant reason why interaction between the human inhabitants of the Outside World and the Armored Knights of the Nest have never occured within living memory. Similarly, this is a likely reason why the Master's dominion has been limited to the Nest and why the humans of the Outside World have not yet fallen under his dominion.  

Other, lesser inhabitants include unknown species of bird, salamander and butterfly.

The Outside World

An image of the Nest from the outside world

Little is seen of the world outside the Nest. From breif glimpses, though, it seems to be heavily wooded as far as the eye can see, possessing a temperate climate. Rain and lightning storms appear to be just as common as they are in the real world.


Dotting the forest are man-made clearings containging human villages. The primary layout of these villages seems to consist of a wide-open clearing with houses and other structures hugging the treeline. The technology of these human inhabitants appears basic but perfectly adequate for their lifestyle: homes are lit with oil-lamps whille outside spaces are lit with torches; weapons include throwing-spears, bows, arrows, and swords; armor may be sophisticated, but from what has been revealed of village defensemen waking bleary-eyed to fend off a beastit is uncertian.

Little is seen of the local wildlife, but it may be fairly diverse, given the vibrantly green environment.
