Wake from your sleep - Excitate vos e somno
My children, your childhood years are gone - Liberi mei cunae sut non
Wake from your sleep -Excitate vos e somno
Fated children, your rest if gone - Liberi fatali somnus est non
Arise! - Surgite!
Search! - Invenite!
Go the the true garden - Veni hortum veritatis
The garden of spring's truth - Horti verna veritatis

With fiery truth burn the evils of this world - Ardente veritate urite mala mundi
With fiery truth light the darkness of the world - Ardente veritate incendite tenebras mundi
Farewell children - Valete, liberi
The day has died. - Diebus fatalibus
