The Lore of Inter-breeding

[Cleretic]

I looked into this mystery a while ago!

The oldest mention I could find of the concept is from a early 2012 post where they describe it as a "theory" based on a cutscene where a black mage character's eye glows in a cool way. That's from the late 1.0 era.

It seems like an idea people were excited about just got mythologized into something actually in the game over the years.

Wow, that is... not even circumstantial evidence, that's just straight-out nonsense. Losing the evidence over the years probably made that more credible.
