The dragon nerd does know the specifics on the big three's dragon magic. "Generally speaking, most dragons can breathe fire. Epithymetikon was unique in that he had a habit of chewing up rocks and spitting out their molten remains. And yes, he was a black dragon: he was also the biggest and strongest of the three dragons who guarded the cities."

There's a pause where Strange mulls things over before continuing. "I went to his remains. He's a grand beast and the remains were quite impressive, but the whole thing felt cursed."
