Early Life

When he was a young man, he swam to get away from his home life.
He was a rowdy kid and often when he broke the rules, his father would beat him. As a result, he would away quite a number of times.
Once when he was running away from his father, when they came upon a stream, cornered, he jumped into the water and wound up swimming for several miles as his father chased him on foot.
When he was 10 years old, a bunch of soldiers showed up and decided to race in the pool that he had created. Strel beat them all and won the prize; a crate of beer. That was when he decided to take swimming seriously and defying expectations.
