Kuthulknoes begins to think to himself, It may be hard to tell for Mortals, but he is most certainly Male.
"Hmm, Everybody seems to have their own Afterlife Dimension, and I am completely fine with that, But, the way things are going there's bound to be countless Mortals sentenced to eternal damnation because of a few misguided actions they made during their tiny lifespans. How the Void is this supposed to be fair? You know what, I'm going to fix this all with my own Afterlife!"
Kuthulknoes creates The Stomach of Kuthulknoes Afterlife Plane. It doesn't necessarily accept only Mortals who follow Kuthulknoes, but rather any Soul that isn't actively worshiping a Deity is drawn to it, Although followers of Kuthulknoes are automatically sent there upon death. The Souls are placed into The Totally Non-Soul Based Candy Jar, a nearly infinite storage space, and are sorted between two categories. Blue Jelly Beans and Red Jelly Beans. All Souls that aren't Evil go into the Blue Jelly Bean category regardless of whether they are neutral or good but all evil and/or blasphemous Souls go into the Red Jelly Bean category. The Souls are then color coordinated based on their category and float around the Jar for a little while, talking and pondering the infinite darkness around them, and then Kuthulknoes reaches his seemingly all-encompassing hand into The Candy Jar and grabs a few of them. He then eats the Souls. The Souls normally remain uneaten in the Jar for a decade at the most, they're usually eaten by the time three months pass.
The Souls both go into The Stomach of Kuthulknoes, also a nearly infinite space filled with a vast ocean of digestive juices more corrosive than battery acid. The digestive juices slowly eat away at the Souls, grinding away at them, slowly eroding their mind, personality, and their very thoughts, for centuries, or decades. By the end of the digestion period the Souls retain none of their past memories, alignment or knowledge of their past life, they become almost primal in nature. Once the Souls are 'wiped clean' Kuthulknoes reincarnates them into an available body of their choosing, Most commonly a Sapient Race, but occasionally one wants to be reborn as a Monster or Animal of some-kind.
The category of the Souls being digested is very important. For Blue Jelly Beans the experience is very blissful and pleasant, like taking a very long meditative nap in a hot-tub. For Red Jelly Beans it feels like they're burning in agony all over their body, the pain is directly proportionate to how evil they were in their past lives. The duration of the digestion varies between Souls, but is usually longer the closer to the extremes of Good or Evil one was. The surplus, digested energy of Souls, or 'Jelly' as Kuthulknoes calls it, goes directly into his digestive tract, which processes the Jelly into a very tiny amount of Essence.
"Good work, if I do say so myself."
Kuthulknoes then stops philosophizing and reclines in a lawn chair, eating Jelly Beans, content to watch other Deities work for now.
