In Jayces' Bio it reads that he was the one who discovered what hextech crystals do
> after many months, the scholars reached a unanimous conclusion: the crystal was worthless. A power-drained hunk of rock. The disappointed clan leaders finally handed the crystal over to Jayce, assuming that even he, with his remarkable intelligence, wouldn’t be able to learn anything from it.
>Something inside the crystal called to Jayce. No, more than that – it sang to him. He couldn’t explain why, but he knew the Shuriman gem still held mysteries yet to be discovered.
But in Camilles' bio her family made their fortune based on the efforts of Camille's Great-Great Aunt Elicia
> The creatures Elicia Ferros found, the Brackern, were not an unending resource, and Camille's family had to look for ways to augment the crystals they had accumulated. Utilizing certain shadow investments in chemtech and runic alchemy, the Ferros family brought to market the less powerful, but easier to procure, synthetic hex-crystals. Such power often comes with consequences, and the production of synthetic crystals is rumored to be a heavy contributor to the Zaun Gray.
Based on how old Camille is her, Elicia must be ancient. So what gives. How can Jayce (who can't be older than 35) discover the purpose of hextech crystals WAY after Camilles' family made their fortune off of them?
