TheUnshaped
The Unshaped are naturally able to survive in space. Within them, Raksha swarm like young seedpods, who occasionally will venture onto shaped worlds. Unshaped look vaguely like nebulae from a distance, with the exception that they are generally far more animate, swirling about like clouds in an atmosphere.
Unlike canonical Raksha, the Raksha of the Space Opera setting are quite literally invaders from another dimension. None can say with certainty how the Raksha came to prey upon Creation. Perhaps they are colonists from another reality, attempting to plunder what they may from a world rich in resources which are alien to them. Or, perhaps some ancient experiment performed by a naive government of ages past invited the Raksha to feast upon the system. None alive in the modern era can say for certain. It is thought that the Raksha have an antagonistic relationship with the Titans.
Raksha vessels are amongst the most dangerous in space, crafted as they are from fragments of dream. They often seem as though they are constructed with gemstones, gas or fluid. Raksha are very interested in taking captives, for unknown reasons. They rarely employ lethal force, preferring EMP weapons or other stunning technolagy.
