The Great Elder’s Knowledge

"What exactly could the source of such 'unlogical' Elemental Crystals be?"

Normally, if one were to ask about the source of 'Elemental Crystals', he would be regarded as someone with limited knowledge. However, it made complete sense to ask such a question now. After all, while the Corrupted Crystals could still be said to be 'Elemental Crystal' in the strictest sense, it couldn't possibly be something that can be found in Crystal Mines.

Moreover, if such Crystal Mines appeared within the domain then the Dragon Clan would have naturally caught sight of it, not to mention that the amount that the Shadow Alliance promised to anyone who joined wasn't something one or two hidden Crystal Mines could provide.
