The only thing I had figured out for them is that they're a terraforming species that work in massive groups to make small planets livable, and they can pretty much endure every kind of air/water condition (short of completely burning alive or freezing to death), most chemicals can't penetrate their tough skin. Dokis with cores (a small bracket with a gem on their body, or sometimes just a raw un-cut gem) are much quicker and more efficient at their craft than others, at the cost of needing to recharge with long periods of rest, they're used in big groups to set down huge patches of lush land. The species is kinda like "What if you could minecraft IRL" and I just rolled with it, LOL.
