There were naturally a number of the ranking Demons and Fae that were not particularly happy with the fact that the defence plan involved them in the most labour-intensive positions, but there wasn't much of a way around it unless they wanted to fight on the front lines, or risk losing the respect of the people.
They did represent and protect a group, but if they screwed up, the locals might not hesitate before sending out messages to other areas that this one might need a new guardian.
There was a lot of internal competition for these spots, especially for the senior spot, as the amount of land in Faerie and the Demon Realms had been limited for generations.
This was the best chance for the younger sons and daughters to get their own territory, and they didn't have to outdo the family heir to get it. They just needed to be powerful enough to protect what they claimed.
