Raze was being truthful when he read the signs that were visible to him. That the magic circle required eight people to enter and only after that, would it activate and proceed to the next step. There was much he wouldn't know, much he wouldn't be able to see.
If a mage wished to hide their work and their enchantments, it was certainly possible, and especially a skilled one like so, which made him think that whoever had made the magic circle wished for a mage to see it on purpose.
Out of everyone here, Raze was the only one that was a mage, and the only person that knew the requirements that were needed. Knowing the person who did this, the Dark Faction Founder was also a mage, Raze had a good feeling that they were heading in the right direction for finding the Golden Globe, but he was conflicted with the news.
