Dairka I is a planet in the Dairka system that has an average size. Though its winter season is two-third the length of its summer season, in the summer the temperatures are still cold.. Its land composition is entirely bare rock but most of it is covered with thick ice. Other terrain includes cave and volcanic terrain though there is one large crater in the north. The crater has been widely studied by scientists. When it was first discovered, there were various small deposits of metal dug out from the crater that has never been found anywhere else in the galaxy. It has been speculated for a long time that the asteroid that landed most likely came not from this galaxy but from an uncharted asteroid field. The person that finds this field would become rich overnight.

The atmosphere here is a very highly concentrated toxin. It would kill all known living species in the galaxy. It is so poisonous, no animal even lives here but there are plants due to the fact that they can filter toxins quickly. Many years ago, the local government in this system started to terraform the atmosphere but abandoned the project. You can still see the initial three complexes on the planet's surface.

The plant life here is sparsely populated and thinly spread. These large, usually leathery-coated trees are all the life on Dairka I. They are called the Peseri trees and they do come in about 7 different species. Peseri is a local word that means poison eater and with this atmosphere, they earn their name. The leathery hide that covers these trees is used for water retention. The planet has no large surface reservoirs and very little liquid water, so the trees need to conserve as much as they possibly can.
