Freyr nodded and sat silent for a little while, pondering how to begin.
"So," he began, "I do not actually suffer from amnesia, although sometimes I wish that were the truth. I was replaced. The wizard Merlin called it a doppelganger, a troll-cursed demon that takes the forms of others. It took me captive and lived my life for me, although to what end, I cannot say. Freyja figured it out and killed it, although it is not permanently gone. It could be anyone. It could be you. I don't know for certain." He took a bit of his bread, appreciating the familiar taste of it.
