It would appear you know about Vikings, however not the correct period vikings.

Vikings only appeared in the Dark ages and almost all of them went raiding at that time. They did not have a caste system, this is how it works in the Dark ages

A random villager decides to become a chieftain.

Other villagers want to be Raiders so they join the chieftain.

The Chieftain buys a boat, and sets sail to raid.

The Chieftain earns a good name and gets more Raiders.

Your caste system was during the Medieval period. Not the dark ages.
