The Ballad of Adler Young, Canto 2.5

If Estmere's legacy has been switched with a lowfolk Bagelmonger's, what happened to the lowfolk bagelmonger?

His fate was traded not with the bagelmonger itself but the one of the baglmonger's son, who was the Old crow.

The old crow never appeared in the story proper (having been dead by fire before it proprely sarted) and it''s been a loong while since he's been mentioned but to recap: He was a changeling, a lowfolk babby kidapped so their place be taken by an elf ho had maaged o adapt to elf society, become an agent of the crown n hen was madean honorary elf and even has monument in thehal of ancesto (thus cimenting his status as an elf post mortem)

The big reveal/retcon here (or at least since the vulp have casted their ritual since it ws mentioned then) is that it happened because of the Vulpitian magic acting through time and swapping his 'lowfolkness' with Estmere 'elfness' by swapping their fahters lineage.

I completely forgot about the Old Crow...
