This is an arrange of Hitoshi Sakimoto's track "Wivern" from Vagrant Story. With a fistful of originality for a friend's roleplay event.
It's a funny one, because I don't usually sing in this style, but here it is ;P

"The mother is revealed to have been an imperial spymaster long before the birth of her children. Now her master's utopia crumbles around her, and as her errant children who refuse to bend knee stand before her, she faces the end of her dream and the end of her life."

Lyrics:
O! Devium fili!
O! Domine mi!
O! Filia mea!
O! Cor urit!
Peccatum matris gravis est ferre!
Tene me, fili mi!
Somnium meum periturum est?
Vae! Vae!
Mater dolet de dolore quae fecit.
Vae! Alea iacta est!
Alea iacta est.

English:
Oh! My Wayward Son!
Oh! My Lord!
Oh! My Daughter!
Oh! How my heart burns!
The sin of a mother is too heavy to bear!
Hold me, my son!
Is my dream going to perish?
Alas! Alas!
Mother is sorry for the pain she has caused.
Alas! The die is cast!
The die is cast.
