I'm sure you've realized your mistake by now, but I'll say it anyway: his age is 22, and was bonded for 13 years. Therefore, they would have bonded when Quincy was 9 years old. You can see why I told you to change the age (or years bonded, that works too).
We could go with the option that the ridiculous excuse of the addition to the Overlord series that shall not be named took, or something similar to it.
