They had very elaborate burial procedures and if you were high in culture, you were even buried on one of the boats and sometimes they'd even sacrifice your slaves to be buried with you. That would really be bad. Imagine being a slave, it's bad enough. Then your master dies, someone kills you so you could be buried with them. Oh my goodness. But certainly they had their own intricate cultural customs, village to village, under this banner of Norse paganism. They also had a very rigid structure of class system.
