TekMat

Lava? Nah, theres no lava here, dont worry our scientists were confused as well, fortunately its just a yet to be determined mineral that is emissive. TekMat seems to be an outer system celestial body due to it mostly containing water, deuterium and Hydrogen as well as hydrous compounds, scientists theorise that it may have absorbed a rogue celestial body at some point causing it to have a fast rotation and this spread out substance, the collision may have been responsible for the rings as well. Before being captured by Tekkoa, this world has suffered some impacts by large major ice crystals and smaller ice crystal clusters hence causing it to look like cheese in terms of texture. It possibly had an eccentric orbit from the start due to possibly being tampered with by an ice crystal at a young age. It is due to this that it was captured by tekkoa eventually after several billions of years.
