The opening is very deliberate, borrowed from another would be author. Anybody care to provide who that might be?
As to brightly blazing, the alliteration it provides, I like. Its a bit like coals glowing sullenly, just a little adjverb to describe the verb bettter. The fire is blazing, it is doing so brightly. This is the purpose of adverbs.
I missed shadows, the other 2 were the ones I was refering to.
Person's it is indeed.
