What does being a Necromancer mean in that world? Are Necromancers just wizards? Is there a Taboo around Necromancy? Is a Necromancer Evil by Default because Necromancy itself is evil? Are Necromancers considered heroic figures, using wasted meat to fight wars or dig ditches on behalf of the community, freeing the living up to pursue other tasks?
The player can be whatever they want to be. And fit into the world however they want to fit into the world. I'm not talking about the Player.

Play your Skald, by all means. What is a Skald to the world? What have Skalds accomplished? Separately, what have -Bards- accomplished that they're separate from Skalds? What defines each of these terms in the game world, not their dice-rolling functionality?
