Karkinos E

The fifth planet in the Karkinos system, Karkinos E is a completely frozen Ice World. Karkinos E is an entirely frozen planet, with ice and snow dominating all of the surface. The planet is covered mostly by vast frozen wastelands that are bisected by a number of deep valleys and mountain ranges. The planet is known to be home to a vast collection of subterranean Watcher ruins, likely abandoned around 12,000 years ago. As per usual, none of the technology left on this harsh world is operational, as though the watchers intended it to be that way. None the less, the planet has a functioning colony of both Human and Emr archaeologists, hoping to unlock the secrets of what was once a largely inhabited world by this mysterious species.

Strangely, on the second largest moon of this world, exists a monolith of unknown origin. The monolith seems to be made out of the same material as the monolith on Phobos, and is roughly the same size. It is though to be built by the same species that built the Phobos Monolith but due the carvings being worn away from the surface by the moon's atmosphere, it is unknown what purpose this creation served.
