possessed

Nine lords of men contrived to never die
accepting Sauron as their liege and king
too late, they learned the promise was a lie
they'd bartered heaven for an iron ring
three elven lords too stalwart to despair
accepted power as a long-term loan
they lightly over-stepped the DarkLord's snare
covertly undermining his black throne
and seven dwarves grew fabulously rich
until the dragons slew them for their hoards
the lust for mithril's a consuming itch
incinerating miners and their lords
but by the halfling Mordor was undone
his "precious" proved to be the ruling one
