Descriptions of violence for me varies on what I'm running. For D&D, which I don't take at all seriously, I go for over-the-top descriptions of violence and gore that nobody could possibly take seriously. During my last session, a creature was killed by a Cloud of Daggers spell. I described it as what happens when you put something in a food processor, except there are no barriers to keep everything contained, so the paladin is covered the blood and little chunks of viscera of the mind flayer.
In my last Vampire chronicle, I shamelessly ripped off Jason Carl in LA Vampire by Night by starting each session with a little vignette of what various people in San Francisco had been up to during the day while the PCs slept. Like little Bobby Joe started kindergarten, Susan Swanson lost her husband of 45 years to cancer, George Gilson finally got that permit to construct some multipurpose buildings in the Tenderloin, etc., etc. Halfway through the chronicle, my vignette focused on the victims of the PCs. Jane Bodmann didn't know where she and her daughter would go after they were evicted. Her husband was an abusive jerk, but at least he kept a roof over their heads when he was alive. The parents of Eugene Thomas have grown increasingly distant from one another as they continue to process the death of their only son, who was violently attacked while on a night on the town with his friends.
