I doubt those are the new relics.

I think those are the new crafting recipe items. The text implies they are forgeries, so maybe high end crafters get their hands on his elite recipes?

"Rowena, the maven of munitions at Revenant's Toll, espouses that proof of an item's authenticity can be found in Gerolt's signature─the mark of Rhalgr, breaker of worlds─and indeed, the master's fervor for the god of destruction in his early years is widely known.
