Lemegeton's Guidebook
"It is said that a curse is cast upon the families of those who die an unnatural death while bearing feelings of hatred and ill will.

Resentment, born from the sludge of Inferno, is an exact manifestation of those bitter, repressed emotions inside humanity.

Once it has chosen a victim, it will follow them forever, no matter the distance, until it can tie them down and make them feel the weight of the pains of hell. Its tenacity is far beyond that of other demons of Inferno, and Resentment is said to have the ability to open the Gates of Hell through sheer willpower.

Witnessing this demon gives testimony to the truly unthinkable power of grudges humans find fit to hold in their hearts and never release."
