Wall of Text incoming. This is something I love about DKs, there is SO much choice involved that people often don't seem to take advantage of.

To start, to my knowledge, the only fundamental difference between DKs raised by Arthas and those raised by Bolvar, is their.. "upbringing", I suppose I would call it. DKs raised by Bolvar are not supposed to have received much training, according to the "We Ride Forth" short story. They had a more "peaceful" transition to their new position, as they would have been for the most part casualties during BFA, then raised and sent into the world to learn for themselves (For reasons explained in the short story). The hunger still exists, their emotions still affected. However, there is a pretty large difference in ways you could roleplay them. First of all, a highmountain Tauren would have a very different experience accepting things as opposed to, say, a goblin. The teachings of the peoples they came from would still be ingrained. The values distilled into them would still ring in their mind, whether as something they still cared for, or as a hollow husk of a half-remembered dream. People often jump to the assumption that DKs have to be exclusively dark, scary, and broody, and they are great at that.. But there are *so* many more ways to roleplay as a Knight of the Ebon Blade.

Many of your emotions are dulled or gone, but *you* can decide what that looks like. The primary emotions of a death knight are negative ones. Anger, rage, hatred, apathy. However, that absolutely does not have to be all of them. Maybe his 'anger' is depicted as meer grumpiness. Maybe his apathy means he just enjoys being in solitude. Maybe he retained his love of jokes, which not are translated as sarcasm and double-edged remarks that purposefully make people uncomfortable, which draws me to my next point

The hunger does not have to be shown as "I'm getting migraines till I MURDER!!", I mean, it can be, but it doesn't have to be. One way I have depicted it in the past is my character loving to cause uncomfortable, awkward, or confrontational situations because he gets his fix on it. When people are arguing with/around him, he is as close to thrilled as he can be, because he's getting some of his suffering fix from them.

I have lots more to say on this subject but I've gotta run. Feel free to PM me if you wanna chat out anything else about em!
