Tiros, the Captain of the Asmodian Cleanup Squad, asked you for help because he wanted to find out more about the history of Kaldor. So you went to the Nagolems of the Ruins and received a Rune Writing Tablet. You gave Tiros the Writing Tablet and he thanked you. He also told you that the records on the stone tablet indicate that the Dragon Lord Fregion was in Kaldor and that the explosion may have been caused by Id.
