The etymology of Baelfire’s name and the meaning connected to that name are interesting to consider. I have read elsewhere that bael-fire is a Celtic pagan term meaning “bonfire” and is connected to the pagan celebration of Beltane, spring’s arrival festival. Traditionally in Ireland, a bael-fire was lit and its embers lasted until morning to welcome the coming dawn of spring. In Scotland, the bael-fire was connected to a purification ritual. Also, the term bael-fire was used to refer to a beacon atop a hill lit at night. Finally, it is a dated term that referred to a fire-pyre used in funeral services.
I’m not sure yet how bael-fire is connected to the character Baelfire, but it’s one possible connection. Baelfire, being a pagan rooted word, could be the good counter-part to the dark one, Zoso, which is another pagan/cult notion. I’m not sure yet, but it’s interesting to ponder.
That’s an interesting name connection I had never read before and your theory that Baelfire is the counter light to the dark one — that is an amazing thought. 😀
