Death road in on a white horse? Death is the white horse!!
I figured with Emily's summoning abilities she would summon a demon horse to ride on once in a while.
This one she named Mortem, (death)
She had to send him back to hell after the civil war in America, he kept going after regular horses and humans. He had a bloodlust for a lot of things but loved the attention he get from mares. :I
And Emily didn't want a bunch of half breed demonic horses running around so back to hell with him! lol
