This seems like a bad idea already.
This is the post it's riffing on : (。ヘ°)
Except I'm doing it with Myconid
Postulate 1 : Fungus breaks down things
Postulate 2: Fungus can utilize elements from things its breaking down in its growth processes
Postulate 3: Intelligence is among the many elements that can utilized like that
Postulate 4: Myconids got their intelligence this way
Postulate 5: They got this from eating god
Postulate 6: God was everywhere and everything but is increasingly lobotomized by Myconids being smart
Postulate 7: Fungus can utilize elements from one organism it has already successfully infected in its infection process on another organism
Given these 7 Postulates I will now explain the monster manual!!
ALTHOUGH
I don't really know what postulates are and think I'm going to need a lot more to make this work so lets abandon this pretense now
What I'm saying is the world was full of animals and perfectly ecosystems and god was spread even through its creation but then as fungus broke down matter it eroded the god and become intelligent.
As it spread through out everything it drags various traits from one organism to another.
Its eventual goal is total entropy , an ungodhead nirvana.
Intelligence creates complexity and complexity is an even better way of creating entropy.
Dwarves: Moles + Rocks + Generic Biped
Elves: Squirrels + Generic Biped + Snakes
Halflings: Prairie dogs + Generic Biped
Gnomes, Pixies, Quicklings, Leprechauns, and all those others small annoying fairies:
Insects+ Biped+Single Emotion
Orcs: Pigs + Biped + Hippopotamus/Aggression
Goblins: Bats+ Biped
Hobgoblins/Bugbears: Goblins + ants
Humans: Generic Biped + Termites
Lizard Men:Isopods + Biped
Kobolds: Bedbugs + Biped
Giants: Humans+ Whales
Ogres: Humans + Elephant Seas
Ogre Magi and Hags: Cruelety + Biped
Dragons: Just Grabbing Anything That Murders And Sticking It Together
Trolls: Remain Spark of Divine Currently Undersiege by Any Negative Physical Trait The Fungus Can find
Demons, Devils, etc: Insects + Dreams +Appetites of Elements
Dryads: Flower Spider + Biped
Nymphs: Desire + Chameleon + Biped
Minotaurs: Fungus rerouting through next generation bring monstrous traits to the child. The bull form of Minotaur is the most well know one
Mermen and Aquatic Elves: Stingrays + Bipeds
Sahuagin: As Above but with Teeth Everywhere
Chimeras, Manticores, Harpies, and other apparently pointless 'crossbreed' creatures: Fungal grab backs trying to encourage concentrated population and militarism and elevation of violent ideals
Slimes, oozes, gibbering mouthers, etc: liquid + hunger
Ilithids: Squid + Flatworm + Biped. The brain eating is some kind of parasite cycle involving introspection
Beholders: Just a bunch of eyes from everywhere + concepts such as Destroy , Control , Hurt
Ghouls: Biped + Saxon/burying Beetle
Yuan-Ti: Actually Avantgrade Herpes
All those giant animals all over the place: animal + localized physics erosion
main take aways:
-Things look like things but don't let the names fool you. Lizardmen are actually more like isopods if you look at them closely
-The nature of reality is made up of elements like hunger, wet, pride etc. Any non-compound noun is probably an element because we can't think further than god.
- Civilization or anything else seen as "progress" is just a fungal conspiracy to speed up entropy
-Everyone and everything contains fungus , your desires fears and dreams are all placed there by fungus to speed up entropy
-the troll is the closest thing to god
Appendix:
I should of used more of the "animal is an incarnation of pride, lust etc" common to medical allegorys so if you wanna use this you should mine from that
