Story

[Sael Jasmua]

If you remember, I was writing a story (now being turned into a full blown novel) about an Zevism who had achieved the Magnum Opus and led an uprising against the oppressors. The main character whispers a short phrase to himself at times:

Gemeganza, O Shaitan iabes caosgo
TRANSLATION
Your will be done, O Satan Lord of the Earth

I'm not the best with other languages' grammar; is the phrasing correct?
