Damn... This was released in Japan back in 2010, but reading this now that the the new Dominaria set revealed that Mother Luti is actually the original pyromancer planeswalker Jaya Ballard(the one who founded the Feral Keep centuries prior)... I'm feeling so much just from her talking with Chandra.
Chandra doesn't know, since Mother Luti spoke to her of Jaya as though it was a different person.
And since this manga was written 7-8 years prior to the reveal, it won't have any role in this manga, and is this irrelevant(not a spoiler) in this mtg side-story centered around Chandra, but reading this manga while knowing the truth still makes me quite emotional.
