At sunrise on Velgarth, a superweapon rips over a miles-wide planar tear to the Elemental Plane of Fire and fries everything.

That's not the problem; Iomedae dodges that. The problem is that the ocean turns to steam around her, Resist Fire doesn't save her from breathing it nor block all of it, and she didn't come to this planet wearing her boots of Teleport. She tries to fly clear of the blast radius and boils alive on the way and eventually falls, unconscious, into the boiling ocean, where the forces that govern greater things than the universe drop her in Reno, Nevada. 

She is noticed lying on the side of a highway and someone calls 911 about an injured person in....metal armor?

The first thing the paramedics notice is that the metal is hot enough to the touch to burn them. The second is that the woman has third degree burns over every visible inch of her body and isn't breathing.
