Wonder how Tidus learned to hunt for and sell treasure? Well who better than a man who sails the seas? Olbrecht used to be a feared name on the seas. He'd steal anything from anyone that he believed could get him rich. But after choosing Tidus as his next victim, he was dealt a heavy dose of humility. One can't hope to best a man who has the sea itself at his beck and call!
After his defeat, Olbrecht found himself bonding with the young dolphin, helping him learn to locate treasures on the ocean floor, as well as showing him ways to get relief without having sex. He's very talented and has shown Tidus a lot of things that have been of great help on his adventures so far.
Olbrecht's weapons of choice are his long, spear-like snout and a beaded whip.
