After everyone is gathered and I see that they are ok, I end the quest as I open the Dungeon gate, tell everyone to come in, and leave Jay to help Leonardo as they are both White Elves, actually Jay is no longer an Elf but he once was, so it will be easier for Leonardo to adapt when he sees what's inside the Dungeon.
After everyone has entered the Dungeon, I close the gate and sneak out of town, getting as far out of town as I can before looking for a place to stay for now.
I find an empty cave, it had a strong odor of rot, so when I enter I find several bodies of Goblins, Wolves and even some dead people, the bodies were rotten and eating this rot were strange small trees with arms and legs.
