Nayuta Herschel, our protagonist, returns to Remnant Island with his friend Signa Alhazan. La Worg, the Continent of Origin (ラ・ウォルグ原初の大陸), in the southeast with autumn.Heimmel, the Continent of the Sacred Mountain (ハインメル霊峰の大陸), in the northeast starts with winter.the Continent of the Abyss (深淵の大陸リズヴェルド), in the northwest starts with summer Oltapia, the Continent of Forests (密林の大陸オルタピア), in the southwest starts with spring.The four surrounding islands, referred to as continents, are each in one of the four seasons. Located in the centre is the Star Garden (星の庭園). Lost Heaven, in turn, is an alternative world consisting of several islands. Unable to imagine that Lost Heaven is part of their own world, people have start to long and look for the imaginary Lost Heaven. Lost Heaven is known for its dynamic nature with flora and fauna more beautiful than one has ever seen, greenery all the way to its borders. When a set amount of light is projected on these shards, they are said to show the imaginary world of Lost Heaven ( ロストヘブン ( 失われし楽園 )). Star shards are known to respond to the seven colours of light. Star shards (星の欠片), a mysterious ore, can be found at the place where these stars have fallen. It is even believed that Remnant Island itself was formed from ruins that fell from the sky. Remnant Island has become known for a strange phenomenon that ruins and stars fall from its sky. It takes approximately half a day by ship to reach it from Saint-Elysee, a port city located on the continent. Home of the protagonists is a small island known as Remnant Island, which is said to be in the middle of the Sciencia Sea. One such believer was astronomer William Herschel, father of the eponymous protagonist, who set sail to discover one such hypothetical world. Humans living on this islands believe that the Sciencia Sea is finite and that there must more beyond its edges. Rather than a continent, Nayuta takes place on the Sciencia Sea, a vast ocean dotted with tiny islands. Instead of the Great Collapse, the catastrophic event that defined the mainline Trails titles' world, the world in Nayuta had to overcome a legendary Great Flood.

The game makes no mention of the continent of Zemuria and makes use of a 'new calendar' (新暦) rather than the Septian Calendar. The Legend of Nayuta: Boundless Trails is set in a different world than the mainline Trails titles. 2.7 Chapter 6 - The Road that Weaves Bonds.
