Here's my attempt at translating:

Spaan fin tah
Meyz faasnu
Zin faal Wuth
Aak goraan
Kos kinbok zeymahziniil
Lahney wah laat
Nir paaliil
Rein wah sul
Yah vomindok
Koraav faal Ven
Evenaar sahlo
Neh gahvon
Dah faal Lein

Literal translation:

Shield the pack
Become fearless
Honor the Old
Guide (the) young
Be (the) leader (of) your companions
Live to (the) last
Hunt your foes
Roar to (the) day
Seek (the) unknown
Recognize the Wind
Extinguish weakness
Never yield
Push the World
