A Protector and a Path Protector were completely different.
The Path Protector was a role that was a combination of a guardian and a teacher. However, a Protector would be the same as vowing loyalty, like a retainer knight.
If retainer knights was a spirit qi professional vowing loyalty to a Creation Master, then a Protector would be a human or fey that possessed a Willpower Rune and vowing their loyalty to a spirit qi professional.
There might be a difference between Protectors and Path Protectors, but their relationships with a spirit qi professional were almost the same. They formed the contract with Law Runes, and it was firm and reliable.
When the Mother of Bloodbath saw Endless Summer vowing an oath, she didn't feel there was anything strange. After all, such help during the World Cleansing was the same as saving a life. It was already sufficient for a fey to repay with their life.
