Could it be anything other than epic poetry? Where else do you find lines like “the master of manhood of all mankind”? What other form could capture a hunter army or a dwarf with sleeves of friendship bracelets?
Frost needs to do more poetry about droods. He claims so adamantly how much he hates them, I think its a case of “methinks thou dost protest too much”! I bet he has a secret collection of drood tolkens. Like a stuff animal of a drood kitty. Perhaps a bonsai tree shaped like a drood tree form? Probably has that chicken outfit from Toy Story 2 at home and dresses up like a real life boomchicken on occassion.
