Latin version of the "One ring to rule them all" poem

A good while back, I was searching the web for a Latin translation of the "one ring to rule them all" poem in the Lord of the Rings. After a while, I managed to locate one, but after showing it to a friend of mine who actually knew Latin, it turned out that it wasn't any good at all. In fact, it completely sucked.

After a while, she provided me with a translation of her own, one which should be much better. Here it is, for the whole world to see.

Enjoy.

Tres anuli regibus Elbium sub divo
Septem autem dominis Pumilorum lapideis in aulis
Novem Mortalibus sub potestate mortis
At unus Atro Principi in suo throno
In terra Mordoris ubi umbrae manant
Unus anulus ad omnes regendos, unus ad omnes detegendos
Unus anulus ad omnes cogendos, et in tenebris vinciendos
In terra Mordoris ubi umbrae manant.

Translation by Katja Rosvall.
