Key terms connect the setting, the devices and the reality-changing premise.
Sonia
The player character named in the official description. She falls into Uncanyon and begins uncovering its mysteries and her connection to a prophecy. This definition avoids later story claims that have not been established.
Finder of Lost Things
Sonia’s title in the official description. It connects her to gathering records, ancient equipment and unique devices. See the story premise.
Fragmentstone
A magical material associated with devices that change the environment. It should not automatically be treated as a crafting resource or currency. See the fragmentstone explainer.
Reality Fragments
A term associated with Uncanyon’s reality-changing premise. Exact ability selection, inventory behavior and limits are not established by this guide’s evidence. See Reality Fragments explained.
Unparallel realities
The official phrase for the realities whose intersection forms Uncanyon’s setting. It describes the premise; it does not specify a fixed count of worlds or an exact switching interface.
Hybrid state
Our descriptive label for a mixture of realities. The developer confirms that blending can be paused and the resulting mixture explored; the label itself is not a confirmed in-game menu term. See the developer statement and open questions.
Semi-open region
The developer’s broad description of the five regions. It suggests room for exploration but does not establish a seamless open world, a linear chapter order or unrestricted traversal.
