Y’know, I don’t think it was ever explained in canon! We’ve had a few Mael RPers over the years who might have have a good answer for you… @thevampiremael, @maelgallia come to mind. Other RPers, or anyone else, are welcome to comment/reblog w/ ideas on this.

Mael had been turned (pretty soon after Marius was turned) by Avicus, another God of the Wood who had survived the Great Fire. Even if Avicus had done a bad job turning him or had recently turned other fledglings, that shouldn’t have been a factor in Mael’s vulnerability to sunlight so many years later, since Mael was old enough to have earned some durability on his own. The only answer I can think of rn is that Mael’s combusted remains were further destroyed by frightened mortals who saw it happen? Idk! It’s an answer I’d like to have. 

Awww thank u for the blargh love and comment about me, that’s very sweet of you! ^_____^
