Kote!
Kandosii sa ka'rta, Vode an.
Coruscanta a'den mhi, Vode an.
Bal kote, darasuum kote,
Jorso'ran kando a tome.
Sa kyr'am nau tracyn kad, Vode an.
Kandosii sa ka'rta, Vode an.
Coruscanta a'den mhi, Vode an.
Bal...
Motir ca'tra nau tracinya.
Gra'tua cuun hett su dralshy'a.
Aruetyc runi cet slarycina solus cet o'r.
Motir ca'tra nau tracinya.
Gra'tua cuun hett su dralshy'a.
Aruetyc cet slarycina runi trattok'o.
Sa kyr'am nau tracyn kad, Vode an!

Glory!
One indomitable heart, Brothers all.
We, the wrath of Coruscant, Brothers all.
And glory, eternal glory,
We shall bear its weight together.
Forged like the saber in the fires of death, Brothers all.
One indomitable heart, Brothers all.
We, the wrath of Coruscant, Brothers all.
And...
Those who stand before us light the night sky in flame.
Our vengeance burns brighter still.
Every last traitorous soul shall kneel.
Those who stand before us light the night sky in flame.
Our vengeance burns brighter still.
Every last traitorous soul shall fall.
Forged like the saber in the fires of death, Brothers all! (less info)
