Yesssss! (Sighs with relief.)
Gandalf is so wonderfully IC here - filled with power, yet irascible and short-tempered. I love his terse explanations to the Twins as to why they shouldn't even contemplate using the Ring; and I also like the fact that (as in Moria) Gandalf is tired after deploying serious enchantment.
The description of Gimli's confused thoughts and experience of pain as he's waking up is very effective too.
I'm wondering one or two things about the Ring of Power though - such as whether, having carried it, Elrohir wouldn't have realised sooner that he'd dropped it, or that Elladan had picked it up. And whether Gandalf wouldn't have sensed that each of them had had it. And I'm just slightly confused - at the end of the chapter, has Elladan picked it up again or is the lineThe cold iron ring pressed against his chest and pulsed lightly. He could take it. He could have more power than he dreamed... He could... a flashback to the previous chapter? I'm hoping the latter!
And the fireflies - lovely device. Could have been corny but I think the fact you put them in from Gimli's POV, and his natural scepticism - the wizard's cracked, but let's humour him, it's often a good idea - saves us from that.
Fab fab fab! More please!
