Final Quest

A tall, handsome man walks up to you. You find yourself craning your neck to see his face, and gulp inwardly, glad that your face isn't red. You HATE looking up at people.
The man stares down at you, his face serious. His features are that of a young man, but he has long silver hair with blue eyes, and wears a white robe.
The man's lips part, and he speaks: "Welcome, children." His voice is low, but, nevertheless, somehow manages to fill the entire meadow. "What brings you here?"
"We drank from the river of death," you answer when none of the others volunteer anything.
The man stares at you, eyes narrowed. "What possessed you to do something like that?" he demands. Then, he turns, and calls something in a strange language. A nymph dressed in a white robe as well walks up to him, and they converse for a while.
You shift uncomfortably while they talk, wondering what they are saying.
What do you want to do?
