The seal will know if you are lying... and if you do, I will simply flood your little bubble and let you rest at the bottom of the aquifer."<br/><br/>Her voice is completely without malice as she says this, almost as if she were reading out the items on the Drowsy Dwarf's menu.<br/><br/>"Now, this oath has several parts. I would ask you to swear that you mean my sister no harm. I would ask you to swear that you will care for her as she cares for you. And she does care for you... to an extent that I am almost jealous. I would ask that you keep knowledge of her as limited as possible, and that her identity not be shared with others."
