If you haven't picked easy mode in the beginning you will have to find the NPC who gives you the teleportation key. To do so you need to have defeated Kaali and then you must talk to Agnes (woman outside the village by the bonfire) and do scavenge hunts with her.
If you find a cave with a large stone door (when you explore with Agnes) and four levers in front of it you are at the right place. Solve that little puzzle and talk with the NPC behind that door.,
Which path are you on? Human or beast path? You have to meet with Commander Cain in the Capital (the one who raided the hidden village). He can be found if you head north while being in the Capital. After you spoke to him, got access to the prison and talked with everyone you need to talk with Commander Cain again and proceed from there.
Funny fact: Amorous was playing with the idea in the beginning to have Miles being a beast dude. But since many people freak out if they can't play as a human (as if 24/7 RL gameplay as a human isn't enough already) he didn't want to take that risk and went with a human Miles.
Back to topic: Quite a few people don't like the idea of having infertile CBs. One theory I have is that both species (humans and beasts) are already barely a match when it comes to mating so the problem gets worse with each cycle and the human <-> CB or beast <-> CB is already too much to work anymore. Plus it's stated that both humans and beasts see CBs as inferior species so they are barely willing to fix the whole problem when it comes to storytelling.
Maybe it might change in the future but then Amorous has to rewrite quite a few things and that will cost time and he doesn't have that much already.
