Tep's Cursed Tombs

You know, I have devoted most of my second life to studying Tep's heritage. So, I knew a bit about his methods...

There are three tombs in Coba Plateau that are of great interest to me. If we presume that the basic story is true, then they can be the clue to this riddle. They can be found to the north, east, and south of the Inn.

Nobody knows what they are for, but I have an idea. And this is where you come in. I want you to find these three tombs and sprinkle them with holy water. Yeah, yeah... "Light will cleanse it! Blah, blah, blah..." Do you think that Light can stand up to the power of Tep?

That's the million gold question, isn't it?! Let's see if the Light really can stand up to Tep's almighty power.

Oh, you don't say...

It seems that the Light really can stand up to Tep's power... But more importantly, Tep's power was fueled by 3 imprisoned sparks? No, this can't be. There has to be more to this...
