Overview[edit | edit source]

Eurya, also known as CelWP T42 d is the closest and smallest planet orbiting the white dwarf star Ira, in Eqien's Galaxy. It is located in the Dream Nebula, and was added in Release 11. Eurya is the only planet orbiting a stellar remnant with life in the Dream Nebula and surrounding areas, making it a popular target for nearby scientific research and studies.

Properties[edit | edit source]

Eurya is around the size of mars, and is quite a bit denser, due to its higher mass. From this, we can deduce that Eurya has a large iron core, expected of something orbiting a white dwarf. Surprisingly, Eurya has surface life, something that should not exist around a white dwarf, a stellar remnant that has shed its outer layers, which would presumably sterilise any orbiting worlds. Eurya is relatively carbon-rich, as its system, and its system's metallicity is quite high, but even so, much tectonic activity is reported.

Appearance[edit | edit source]

The day side of Eurya is visibly purple, as the pigments from the life present on Eurya's surface tinted it this way, from an as-of-yet unknown pigment. A dark brown hurricane is present, fueled by the temperature differences. Several mountain ranges bordering the terminator line, created by tectonic activity, can be found.

The night side of Eurya is likely mostly uniform, being a big sheet of ice. The ice is warmer than it may be, as the atmosphere distributes heat from the hot day side to the night side. Tectonic activity on Eurya may also have created pockets of liquid water under the thick ice, some of which may be able to host life.

Life[edit | edit source]

The only explanation is that Eurya's life formed after the death of Ira and its transformation into a white dwarf, around 540 million years ago. Eurya's life is mostly made of plants and bacteria in the soil and air, and some primitive animals and other organisms. As it orbits so close to such a dense object, Eurya is tidally locked. Not much can be found on the night side. Eurya itself is around 4 billion years old (as is Ira itself), much older than the life on its surface.
