Wait, without his fire powers, how does any part of Elmal Guards the Stead make sense? Half of that myth is specifically about the power of flame. When the stead is assaulted, it is by chaos creatures that represent disease: first is the eater of skin, which makes abscesses and bleeding wounds open on the skin. Second is the Author of sores, which causes wounds to fester and last is the maker of bad growth, which causes one's insides to multiply endlessly (i. e. tumours).
Elmal slays them all with fire in different ways, either through a burning spear or using the sun to turn them to ash and that's important. I mean, a myth isn't just a thing the gods did, but it illuminates something, namely it tells how one can fight disease through the use of flame to cauterise and purify. But without fire, none of that part makes any sense, both from telling what Elmal does/can do and from telling us that Orlanthi know flame can fight the Chaos of disease. So what is up with that, now?
