"See? Told you!" My brother looked at me smugly as he designated the wide expanse of water in front of us.

We had walked 12 days since leaving our village. It had all started as a stupid bet: my brother had heard, through a friend of a friend, whose grandfather had travelled "as far as his feet could carry him", that if you walked long enough, you would reach the end of the world. I had said that was ridiculous, and my brother had predictably challenged me.

But I wasn't convinced. It was only water! I wondered what lay beyond.
