Inviria is the sole ecumenopolitan planet located within the Empyrium and by far its most populous, hosting a quarter of the collective's population. Located within the San System in the Western Reaches, Inviria was formerly positioned within a memoria space inside the Alkidian Superanomaly as the capital of the Invirian Ascendancy, having been transported to its current location in 474 CE by Guinevere with the assistance of the memoria.

A dry, ferrous, arid planet, it hosts a subsurface ocean commonly found on ice moons on the outer edge of star systems, suggesting that Inviria formed at the outer edges of its solar system before being catapulted inwards, warming the latent atmospheric components within its crust and forming an atmosphere, preserving the ocean beneath. Theories suggest that the planet formed naturally outside of memoria space before being subsumed within it but are unsure as to when this happened. As a result, the origins of the oceanic ecosphere are unknown, i.e. it could have emerged naturally, or have emerged from thoughtforms from the planet's first Empyrean inhabitants thousands of years ago. Due to its positioning in memoria space, the ecumenopolitan nature of the planet was attained through strongly protected, sustained thoughtforms imagined by the local Xahnamohan, which, except for minor restructuring tweaks prior to orgone transmutation, were essentially unchanged when the planet became truly "physical". Because of this, Inviria is unique among planets of its kind for its immaculately preserved, albeit permanently shadowed original surface, and its incredibly diverse subsurface ocean.

Since it exited the memoria space, Inviria has become a focal point within Empyrean trading networks as it is incredibly import-heavy. Much like neighbouring Eos, its main export is human labour with other forms of trade running scarce. Internally however, thriving industries underpin the high quality of life of the planet's citizens. This has drawn questions as to how pollution should be managed though - a problem that was nonexistent during its times within memoria space. To widen its external outlook, the planet (like all Invirian planets) is under Sanian suzerainty and managed by a transitional reorganisation commission (TRC) to integrate it into the Empyrean community, a process that may take hundreds of years given its size. As such, it is similar to many Imperial systems and planets in that self-rule is heavily limited, except that it is managed by San, a free planet. Given its immense population, the integration programme is controversial among many, especially other free planets, who claim that Inviria stands to gain disproportionate influence over the entire collective.
