Faith is Madness

How is it that you expect to face your enemy when there are so many who are weak among your people? Unless there is something you see in these comrades of yours that I do not. Could there be a quality worth your efforts? There are others who have passed this way, others of your kind. They too had fallen. Each because of a weakness... I remember a lady dressed in ornate clothes of red. She fell into madness, but her bravery was of note. She thought to face the fatebringer herself. Arrogant or brave? I cannot decide ...

Find the mouth of Terror that swallowed the lady that the Stranger spoke of. Then find a way to cleanse the caverns. Return to the Stranger when done.
