Warspheres

Introduction and Origins
Kroot Warspheres are giant spaceships built and used by the xenos species known as kroots. it is the main spaceship of the kroot race, and thus, their only way to explore the galaxy without the aid of the Tau Empire. A wasphere is a fairly primitive spacecraft when compared to the vehicles of other races, but it's the most technologically advanced construction the kroots have. How the primitive kroot can build them is up to speculation, but most members of the Ordo Xenos and Earth Caste scientists theorize that, after centuries of ork consumption, the kroot have gained an inherent knowledge of technology, just as ork mekboys do. As such, they are able to instictively build spacecraft good enough for space travel, and that is aided when they combine it with Tau technology. In fact, kroot warspheres have a massive advantage over tau crafts, due to them havin a slow, but functional, Warp-Drives. With Tau not having mastered this tech, kroot have a definitive advantage in regards to mobility, even though everything else is inferior to almost any tau vessel. This makes Earth Caste scientists very mad, being utterly unable to understand how the warsphere work at all, which, in turn, makes kroot cackle histerically when asked. The fact that the kroot don't need navegators to jump into the Warp and yet they don't get attacked by daemons (for the most part) suggests that the ork theory is more correct than originally thought, due to them also being capable of creating ships cappable of moving though the Immaterium. According to some sources, the kroot possess some sort of sixth sense to navigate through the Warp and not end up lost, usually finding inhabitable planets at the end of their travels, probably to find the rarest DNA strains to add to their genome. This could also be a reference of many bird species having some sort of "inner compass" to make them find their destination through kilometers and kilometers during their migrations.
Functionality and design
Design-wise, warspheres are effectively giant egg-shape spacecraft comprised of various ring-like structures around a center that houses most of the engines and navigation personnel. The size of the ship allows it to be a fully-functioning flying town for millions and millions of kroots. The size of these things is ridiculously big, usually surpasing in size to all tau vessels and most of the Imperium's biggest ships. The question of how they can build such massive structures when they don't have any sort of orbital construction facilities is beyond our understanding, and probably just GW not really caring about things as gravity (or maybe they are just going by the ork theory, which probably makes Earth Caste scientists even more baffled). It also has the neat function of being able to bury itself once landed, and serve as some sort of colonial structure for the kroot to start colonizing the planet. However, the warspheres are far from perfect: in regular space, they are very slow and their weaponry is not that effective, due to their power output systems being very primitive. As such, they are relatively vuilnerable, due to being a massive target that can't defend itself very well. Kroot won't use these crafts unless they are either paid really well, they are guaranteed their protection with guardian ships or they are in the process of colonising a planet.

The warsphere can be used by Tau fleets, but I don't have the game, so I don't know how well or bad it does.
