I kinda got hung up on some stuff with the story relating to Eric.
So he says outright that he is the son of Lahabrea, but also the son of an ex-Lahabrea. Athena is his mom, the ex-Lahabrea.
Then it brought up this idea that Hesperos had an obsession and wanted to be Lahabrea's son, and whatever transformed him into the vampire caused that to get amped up in the transformation.
That calls to mind Tempering, but I'm more hung up on the family connections.
I was thinking they might not only do a revisionism for Lahabrea by making Erich the Lahabrea that we know, so we see his eld past and form a bond and feel slightly bad about killing his tattered 12,000 year old madman self.
They could also apply it to Themis and our WoL. Of course, there's just pieces on the board and not a lot of material right now, so it's just passing speculation, but perhaps Themis is Elidibus's twin brother, and they're the sons of Venat. Perhaps current Azem is the Hesperos in that situation (and us by extension).
If it turns out the basis for Ye Olde Tempering was based off of seeking the adoration of a parental/mentor figure, then they could still deliver us a weak as hell version of, "The WoL was tempered to Hydaelyn." that's still not tempering, but is in the personalized root of it.
Probably not an an eventuality. Just musing.
