Elise

Elise levers herself to her feet and slowly walks into the chamber's center. Int he language of dwarves, she whispers, "'Much has changed' and knows not of our people... It says it is not a spirit, but what else of Hevia could survive?"

She regards the unnaturally-moving droplet and continues in common. "You say that you would be interested in knowing how we have released those trapped here, and you suggest that we might know more of you. You surely know of barter. Might we trade knowledge for knowledge, not-spirit of this place?" She speaks as she knows merchants do when trying to interest a customer, using the skills she learned from her father in her youth. "You know that nothing we learn can really hurt you, and may be able to stop losing other assets with what we give in return."
