Considering we find the node with his recording imbedded in it in Azys La, where they were known to experiment with Dragons, it isn't a stretch to imagine they the Allagans also used dragon scales to ward off tempering, albeit unwillingly harvested. Strengthening this connection is the fact that Owen says it was Amon himself who put a halt to his plans of trying to cure those tempered that could be cured. And for those of us that remember said cutscene it served as a teaser for Fandaniel being Amon, I remember wondering what connection could Fandaniel have had to Allag at the time.

tldr: Its pretty cut and dry that Amon/Fandaniel is referring to an Allagan researcher called Owen who created his own warding devices while investigating the tempered.
Ah, right. Good call. That's almost definitely it.
