There wasn't an easy way to explain who the children of the deities were.
Strictly speaking, Gloria belonged to the descendants of a deity. This is because the predecessor of the Northern Witches was from a powerful organization. This organization, which had existed for a long time, had leaders that were even once chosen to be the Goddess of Magic. That was also when the north gave birth to many powerful Witches in that period. Some of them even rivaled the deities.
However, that was a long time ago.
The only place to have records about the 'Chosen Northerners' was in ancient literature.
As a pure Northern Witch, Gloria more or less had some inheritance in her blood, which was similar to the Elven noble in front of Soran. Some of them had the opportunity to strengthen their talents, and others had already exhausted their bloodline powers.
