"You look like you've seen a ghost, Vanya," you say.
"It's Basileios, Vanya," says one of the warriors who accompanied you. "Basileios! Returned to us from the dead!"
"This isn't Basileios," says Vanya, his eyes darting from one warrior to another. "I have heard tales of spirits of the ice, who prey on the hopes of travelers only to lure them to their doom. This is surely one such creature." He gestures to the nearest warrior. "Quickly, destroy it."
The man he pointed to begins to draw his sword from its scabbard, but you see he is hesitant. If you're going to regain control of your tribe, it's now or never.
