Yup... no relic to be found.

Summary Hahaha... Well, that's an unexpected turn.
Then who stole the relic?
You're not gonna believe this, but... it was the Yeongam of the East!
Jang Iksoon NPC Knowledge here, the Hyungam of Dalbeol has confess- Huh?

Summary I knew that, when you got everything taken care of,
you'd end up here, and... see? My intuition is never wrong.

The relic was stolen! I put my faith in you, My Lady!

Quest Text Dolswe NPC Knowledge! Adventurer! Oh, though it's "traveler" now, isn't it? Long time no see!
I know you two would get along marvelously.
