Everyone has a different approach to character creation. Some people have to plan everything out on paper beforehand, others start with a blank slate and jump right in without any solid ideas – creating the character spontaneously though organic roleplay. Many of us are somewhere in the middle. But what about when you're considering a Forsaken character?
The Forsaken are defined by the fact that they're dead and incomplete. A lot of roleplayers expand on that by taking away parts of them, physically or emotionally.
A lack of physical senses is common in Forsaken roleplay. After all, we're talking about a race of corpses that are missing jaws and eyes on their character models, who make jokes about being colour blind, and, in the starting zone, there's that guy freaking out about how his hands are different. (He's my favourite.)
A lack of emotion is common too. We have Forsaken NPCS left and right telling us that their feelings aren't the same, or that they're missing their emotions entirely. My favourite example is Dalar Dawnweaver, a former Mage of Dalaran and quest giver in the Sepulchre who asks players to kill twelve Dalaran affiliated Humans, saying the reasons he wants them dead “range from hatred to anger to betrayal” but assures us that they are all legitimate gripes.
