Don’t know if there were voyagers or what.
Some claim that the explorers “took” native women as they came to villages.
Think of the locals. Here are some rock stars wearing fancy dress with boom sticks speaking foreign tongue and with material goods. If you go with them, you just may get more candy and treated well.
Or stay in the village and watch Grock challenge Turok to a battle of strength for your hand.
