Palantir of Fortune: Lost Tales/HoME

[Guinevere]

as repeated by Celegorm in Nargothrond. (That capital S sure was a give-away! )

Be he friend or foe, or demon wild
of Morgoth, Elf, or mortal child,
or any that here on earth may dwell,
no law, nor love, nor leage of hell,
no might of Gods, no binding spell,
shall him defend from hatred fell
of Fëanor's sons, whoso take or steal
or finding keep a Silmaril.
