Guild Merchant

Judging from her appearance, she is a merchant sent by the guild into the dungeon.
She is organizing goods and writing in a ledger when her ears perk up as you approach.

"See that pile of rocks over there? It is not moving right now, but I hear the guild will send people to investigate it soon."

"This cannot be... We went through all that just to get here."

At your words, she raises an eyebrow, thinks for a moment, then clicks her tongue.

"Sorry, but the deeper parts of the dungeon are blocked off... No one can get through. This is as far as you can explore for now."
