"Can no one inject "Shifter" into someone?"

Thought the homeland might not have that capability, it is safe to say that logically speaking, there has to be some in-universe way for "original" shifters to be created.

Something that also occurred to me... eventually Titan Shifters, if there's no way to create new ones, could go extinct except for one because think about it...

When Grisha killed Frieda Reiss, they were both titan shifters and so consequently you had two titan shifters fight and then you had just one. Assuming there are no more titan shifters being made elsewhere in the world, the worldwide population of shifters decreased by one.

So, in theory, you could have a situation where a titan shifter could eat all the other shifters in the world and then "there can only be one."
