There’s a decent chance you already know this, but that bit is probably a reference to Harry Potter and the Wastelands of Time. I don’t think that fic describes what did its Atlantis in in any great detail (though it’s been a year or two since I read it), but whatever it was, it was probably an apocalypse of subtype dug too deep and awakened an ancient evil. All the absurdly lethal skeletal guardians left lying around seem to point in that direction, at least.
On the other hand, there’s enough references to D&D magic floating around that balefire wouldn’t be too outré.
