A Viking in a position of power does not need to labor in the fields. Labor is for the weak! A Viking of power takes what he wants, and need not labor for it. A powerful Viking plunders all and takes what he wants!
It takes a lot of labor to harvest roe (ろう) so that’s what the Viking decides to take first! Roe is delicious, but it’s small and delicate. Vikings don’t labor for their own roe! They take it and eat it!
