User blog:Nexhae/Having problem with Mage of the Begging’s gender

I have a question. During Ala Alba’s mission in the grave keeper’s palace, every member of Cosmo Entelecheia (including Dynamis) was calling the Mage of the Beginning 'he'. But in chapter 325, in Fate’s dream, we saw that the Mage of the Beginning was a woman. Then why the members of Cosmo Entelecheia were calling her ‘he’? Even Dynamis, who was a very high-class member of that organization, was telling that the MOB was a man. Of course, that would not make sense if he didn’t know about the MOB’s true gender. Because even Primum (Fate – 1) did know her true gender. Again, people were asking about her gender even after the release of chapter 325. The question about her true gender remained until the release of UQ Holder. But why that happened? When the author already showed us the Mage of the Beginning’s true gender in chapter 325. Does anybody have the answers to my questions?
