Fist we meet Tristan, who's mother dies from the sorrow, because her husband had died. Only having baby was saving her life, but when he had been born she died. She told that her boy was born in the great sorrow and that's why his name will be Tristan (trist in french is sad). He had a tough life from the beggining. He was high-born but no one knew including Tristan.
Tristan is captured by the pirates and when they are on the board big storm beggins. The pirates fineally decided to give up on Tristan and they put him into the boat and they left him and survive, the pirates and Tristan.
There is something about the sea. It is deciding about his life.
