Lome didn't understand why the Great Sage suddenly started mingling with what she considered to be an insignificant little mercenary group. Although Komer had erased her memories about the Church of Light, he had restored her other memories using an extremely complex form of psychic magic. As long as she touched upon these memories, she could gradually recall them, so she wasn't completely ignorant about the mercenary situation on the Continent.
Even in the Northern Continent, where mercenaries weren't widespread, a small group like this would be considered bottom-tier. And even a mercenary group with dozens or hundreds of members might not have a Mage. At most, having two or three Magicians would be quite remarkable.
Lome couldn't imagine anywhere on the Continent that would have a Great Sage and someone of her own status act as their Mage, even if it was among the few super-large mercenary groups—they likely couldn't afford it.
