Who are the Rhutums?

The Rhutums are advancing more quickly. We need to know more about them in order to make a plan to counter them. Go and learn about the Rhutums.

Rhutums will be one of the greatest threats to Calpheon, even worse than Catfishmen. We can't just sit here and watch.

Now I know a lot about the Rhutums. I'm going to share this information with the soldiers. I wanna say thank you on their behalf.
