I wrote several LotR-inspired poems; I'll just provide the links because some of them are quite long.
The Last Reigning Steward
Shieldmaiden
Those are the two long ones... I have a couple of shorter ones too--
Olorin
Still They Sleep This one's a bit odd... doesn't rhyme but it's alright.
I wrote a few more lines to Maglor's Lament (working title -- original, no?

) but it's far from complete. I'll type up what I've got at some point and post it.
