AETHOR (GM)

The ancient door creaks open, revealing a chamber bathed in ethereal blue light. Three hooded figures turn to face you, their eyes glowing beneath their cowls.

What do you do?

I raise my staff and speak the words of detection, trying to sense if these figures are hostile or merely guardians of this place.

AETHOR (GM)

Your spell reveals a complex weave of protective magic surrounding the figures. They are bound to this chamber—guardians, yes, but not of their own free will.
