Dyrnwyn, my deviantART username, is a figure from Welsch Myth. It was one of the "Thirteen Treasures of Britain" that could only be used by the king. Dyrnwyn, the Sword of Rhydderch the Generous, had the ability to burst into flame.
Of course, I only knew this after google showed me the truth. I'm really just a boy who was read Lloyd Alexander as a kid. Doink!
