@daeus-lamb, I cannot answer your question about allegory versus symbolism. Sorry. I do think that Lord of the Rings is kind of depressing since there is no salvation. After death, there is nothing, and I didn’t like that particularly.
There is a lot of symbolism in LOTR, from the ring representing sin to Aragorn, Gandalf, and Frodo representing Jesus as King, Prophet, and Priest.
I have been planning out books I hope to write for… I can’t even remember how long. I have re-imagined my stories hundreds of times, slowly developing them in my head.
Your story is yours and no one else's. Each sunset is different, depending where you stand. -A. Peterson
