Kenshin: place of the broken and the lost

[edised]

For one they make a good consistent danger for the domain.
The original idea of the domain was they are part of the dark lords torment, the dark lord has a-lot of prejudice, and the wildmen are a dark reflection of themselves and their beliefs. I am unsure if they fit in my new interpretation.
The wildmen are a lot like the Yahoos from Gulliver's travels.
