Most, if not all, sentient species can interbreed. Their child would be called a perfect hybrid. Perfect hybrid means that their blood is equally distributed between all species. In this case 50/50. If a perfect hybrid has a child with a non-hybrid, their child would have blood with an ratio of 25/25/50, or 50/75, making it a hybrid and not a perfect hybrid. Normal hybrids are not fertile.Â
If a perfect hybrid has a child with someone of one of the same races as him, the child has a 50/50 chance to become the same as either of its parents.
In this way, it is possible for a hybrid to exist of more than 4 or even 16 species, although this is very rare.
Known perfect hybrids include: Elaya, Ellian, Rhowar, Lunosa, Blaize Emberpsark, Endellion Nye
