You’re relying on a very pre-RQG retcon understanding of Elmal.
Forget the past twenty+ years of Elmal’s development and mythology.
Yelmalio is Elmal+.
Everybody says so.
Learn to love Yelmalio.
Everybody does.
Yelmalio has always been Elmal.
Everybody knows.
Yelmalio is beloved by everybody.
Hell . . . In the next edition, we learn that there has always been a Sun Dome at the Castle of Lead in Dagori Inkarth.
Yelmalio and Zorak Zoran are buddies.
There’s a whole trilogy of buddy comedies planned that details their wacky adventures.
Everytime Zorak Zoran uses his Fire rune, he quips to Yelmalio, “Jealous, little Elmal?”
They glare at each other. Then Yelmalio cracks a shimmering smile and they both laugh. Zorak Zoran slaps Yelmalio on the back, a bit too hard, and then they laugh some more.
