Vanjarls rule the Vanir with both priestly and magical power.
Vanir form the bulk of the military and society in the Early Age of Vanheim. Their Glamour ability allows them to pass disguised and create mirror images in battle. The Vanir can sail the seas.
Statwise, Vanlade is basically just another Vanadrott, with better armor (chain mail cuirass as opposed to lightweight scale), the maximum amount of magical skill a vanilla Vanadrott can start with (A3, D1, B2), and a few slightly lower stats (most relevantly HP, strength and magic resistance).
Apparently, Helheim can get Vanlade as well, and he is a bit more special and helpful to them. But, for Vanheim, he's, again, just another Vanadrott.
