With the basic definition of a gang nailed down, I commenced browsing various Internet search engines to find more information about pre-1960 gangs. I was first about to settle for some classic Caribbean pirates, but after some more reading I eventually ended up going for the Norse Vikings. They were kinda the pirates of Scandinavia anyways - it was just way easier to find reference images I could use.
I then went to find a story I could use for inspiration - yet again searching through multiple texts. I eventually found and decided to use the story of Olaf Tryggvason, who was the king of Norway from 995 to 1000, he also played an important part in the conversion of the Vikings to Christianity.
Personality: Committed, selfless and clumsy
Edgar is a 12 years old boy living in a Norwegian viking village around the year 1000. He lives alone with his father who is the town's local blacksmith. His mother disappeared a couple of years ago in the midst of a viking raid. Nobody know what really happened.
Edgar's dream is to become the mightiest viking warrior there is.
