The Four

First, we have War. Obsessed with the gun in the end, this was how he was done.

Next, we have Pestilence, in his eagerness to spread his disease, he stopped to do as the humans pleased.

Then there's Strife, who in his entire life wanted, but discovered everything he had had previously been bought.

And last, we have Death consumed by his sadness, and driven soon into madness.
