Vinnskor Storm Jarl Rego is not a real Jarl. Nor was his father. His grandfather was Jarl Ogurr of Vinnskor, but as trolls destroyed the town and killed the old Jarl decades ago, the position of Jarldom died with him. Jarl Rego's father turned into the slave-business, and taught the trade secrets to his son who now commands a small fleet of longships raiding the coasts of the Sea of Claws from Kislev to Bretonnia.
On one of his raids to Bretonnia, Jarl Rego managed to capture tall, slender and very agile creatures with super-human speed and agility. As these "elves" were unsuitable for hard work in the logging camps where the Jarl normally sold his slaves, he decided to throw a few of them to fill the gaps of his Blood Bowl team. After seeing their performance in a few matches, Rego decided to arrange fatal training accidents to all his other players and ordered his slave-ships to raid solely the coasts of Bretonnia and capture as much of these elves as possible. After training the team of his elf-slaves in secrecy, Jarl Rego has now decided to take the NSL by storm; his Vinnskor Storm.
