So this is my first attempt to translate something that I didn't write.  It's from Lord of the Rings, and I'm guessing that my translation is WAY off.  I had to use some synonyms since I couldn't find some of the words.  Please edit.

Out of the Great Sea to Middle Earth I am come.  In this place will I abide, and my heirs, unto the ending of the world.

Ftu wrr naem ean ne kxam atxke oe z<alm>a'u.  Mì fì'u tsenge oe r<ary>ey, sì oeng 'eveng, vay maw kersusey kifkey.  

Irayo.  

[kewnya txamew'itan]

Ftu wrr naem ean ne kxam atxke oe z<alm>a'u.  Mì fì'u tsenge oe r<ary>ey, sì oeng 'eveng, vay maw kersusey kifkey.  

I'm just going to gloss this so I can see what you've done:

Ftu   wrr      nawm ean  ne kxam  atxke oe z<alm>a'u.  Mì fì'u          tsenge oe r<ary>ey,      sì   oeng 'eveng,  vay    maw kersusey kifkey.
from outside great  blue to middle land   I   came.        In this-thing place    I   will be living, and us    child,     up to after dead      world.

wrr isn't needed.

Sea is txompay not nawm ean (they're both adjectives anyway so the syntax there isn't great).

middle earth doesn't translate well but if you do it as you have, you need to adjetivise kxam with le- to get lekxama atxkxe.

Fìtseng not fì'u tsenge

<ay> is a more accurate translation of the original.

Kelku si would be a better verb to use than rey.

oeng is us, my is oeyä

children is ayeveng, 'eveng is child.

until the ending of the world would be vay tì'i'a kifkeyä

So it should be:

ftu nawma txompay ne lekxama atxkxe oe z<alm>a'u. Mì fìtseng oe kelku s<ay>i sì oeyä ayeveng vay tì'i'a kifkeyä
