Took some doing,but I managed to translate it.Not bad,however there are some minor errors.Niin means "them",I assume you meant "Nen" or "Nine".All other corrections are in parenthisis.

Dovahzul translation:

Faal Nen wahlaan mii ahrk mu kos
 diistkiin
Akatosh un bormah
mu kos bahlaan dov
 

dov praag nid zahkrii
mu muul jul frundiin
nuz rah hiif must(muz?) dojrah(doj rah?)
ahrk gaav pah niist ov

kaan ofan must (muz) thu'um
ahrk gruth pah dovahhe
daar lein, kiindahqaaru
nii fon nust forson

ruz rok ofan su'um,
Alduin, kogaanne
voknau kaal kinboku
mu in mintiinon

Alduin

Alduin

English:

The Nine built us and we be
 firstborn
 akatosh our father
 we be worthy dragonkind

 dragonkind need no sword
 we muul(???) man gladly
but god help must(men?) dojrah (learn god?)
 and get all their trust

 Kyne give must (men?) dragon shout
 and betrayal all dragons
 this world, our birthright
 it seem they abdicate

 then he give breath,
 Alduin, blessings
 upon champion our
 leader we master infinity

Other than the minor errors,this is a very good poem.

I want to start contributing to the library, but i cant ever find the time to write! Im so caught up with languages and translating. I will crank out a poem for sure though
