I'll translate some when I have time. I'll keep editing this post until the translation is complete. Oh, and please don't mind my style or anything, for now it's just a plain translation.

The instant Randar touched Vaal's body, he cast the seal spell using the seven stones!
---
Randar: "Vaal Seal!!"
---
Randar and Vaal radiated enormously.
---
Randar: "The castle has started to break down! Everyone, escape quickly!!"
---
When they came to their senses, they realized they were on the summit of mount Beryll. In front of them were Randar and Vaal, who had turned into statues of stone.
---
"W-Why have they become like this..."
---
Randar: [Please do not be sad.
---
There is nobody who can defeat Vaal. Therefore there's nothing else that can be done than using this magic in order to seal him.
---
When Vaal resurrects, we can't do without friends like you.
---
Conveying this to your children, is the mission that is left for you. You understand that, don't you.
---
Well then, I'm tired, so I will go to sleep very soon. Thank you, brave warriors.
---
I will never forget about you. Never.....]
---
The story that is written in the Scriptures of Randar ends here. Therefore, it's unsure what happened hereafter.
---
However, as long as there is "friendship", the world can be saved - even if Vaal would resurrect once again.
---
"The Scriptures of Randar". These contain the story of Randar and the heroes who opposed Vaal, the ruler of the demon world.
