Dimensional Researcher Lias:
A Dimensional Rift has occurred here. I'm Lias, and sensing something strange about the Dimensional Rift here, I've come to research it.
They say this area used to be called the Catacomb of the Witch. However, it's a completely different place now, and you'd best not let down your guard.
Collect 10 of the Superior Giant's Codex Fragments and Rune Stone Fragments that you receive after participating in the operation. They can be exchanged for the Superior Giant's Codex and Rune Stones, respectively, so tell me when you're ready.
Also, if you want to leave this horrifying place, tell me. I'll let you out.
