There were a total of ten outposts that were scattered all around the continent.
It would have been more, but it seemed that this was the limit with how they spread out the portal arrays. If they didn't spread them out this far, then they wouldn't have covered the continent so completely.
It would have given them more space to create more outposts.
However, there was an explanation for this.
"It's simply because they had to do this so they could operate in secret. If they were to abduct too many people from a small area, then it would have raised suspicions."
They took advantage of the one thing that no one really cared about in this world full of magic and fantasy.
It was the fact that this world was a dangerous place to begin with and it was common for people to disappear. It was natural for a few people to disappear in most places every year, which was why no one investigated when these people went missing.
