Well you grapple everyone escept yourself with the Tentacles. 2 guards come running up the stairs; one has a Basterd sword and the other a Shortsword and wooden shield The second one looks barely 17 years old and is visibly scared. G1:"Halt! What are you and the----ick--Drow doing here?!" He says to Crona.
"Leave the Drow alone. He is with us. If you so much as touch him, you will regret it for the last, short, pinful moments of your lives."
Whisper(in whatever language they have in common besides Common, I'm sure they must have one): "Calm down. They're just doing their jobs. There is no need to threaten them, and doing so will only make the situation worse."
G1:"Then could you explain why there are massive black tentacles coming out of the floor?"
"Certainly. Our friend was merely using a spell, and it went awry. This sort of accident happens often, does it not? If damage has occurred, we would be happy to reimburse the owner. But I assured you it was purely accidental."
