It was all silent at the docks when a body would be hoisted up from the waters and place, gently, on the ground. Many people looked and saw the oh so familiar faces and couldn't hold back thier tears, as it was Sabo. He was dead, to put it simply, last night there was a large part on the docks and people got drunk. So it is presumed that Sabo got so drunk he fell into the sea and drowned. Sadly, this was no joke and this man's journey had ended before it could even take off.
