Author's note: I am so sorry, I forgot to update chp. 1 and fix the grammar. I am not sure if I will continue this story on because chp. 2 2, 5 , and 7 will be barren of their windings.
-Long ago two races ruled over Earth. Humans and Monsters, between the years of 200-350 AD a war broke out between the two "races" and after a long series of battles, the humans were victorious. The greatest of their magicians cast strong spells that created a barrier surrounding a mountain, which sealed the Monsters underground. However, this is not the whole story. At times like these, (like in our world) Science isn't a popular or even a common concept yet. What dominates these times is religion(s) and this all ties in the souls of all species; Humans, Monsters, and animals. There are three main traits that affect all three of these species. Physicality, Mentality, and spirituality. I will describe how all three traits affect one another, higher, lower, or all around.
-Physicality means physical strength, mass, weight, and endurance (Well as physical material). Mentality means emotion, intelligence, and sanity. (And so much more, that is just the surface of it.) Spirituality is connected to both of these but more often is connected to mentality, spirituality is belief, the spiritual world, your soul, magic, and faith. Your brain has a spiritual side to it, seeking emotional pleasurement through art and music. As does the Human soul and Monster soul help fuel the body through the energy that cannot be seen or even comprehend by the mind.
-These are only the basics and even though they are complex, now I will go deeper into the description. Science. Monsters aren't one species, as we have seen there are different types of Monsters. Plants, machines, amphibians, and mammals. What? What do you mean by "what about the skeletons?" Oh, I forgot, they are the undead. They are more complex than something that is alive, plant, or mechanical. I will save their type for another time. You have another question? "How do I know these are species? Just by looking at them and knowing that each of them is affected by physical traits. Undyne overheats, and Asgore gets sick. Not only that but I can compare them to our own world of mythology, science, science fiction Philosophy and so much more.
-Look at Asgore, Toriel and Asriel. They are what we would call sentient, evolved or even aliens. But in this world that is how this all works. They exist there and not on our own. (Who knows maybe they once did.) Now I will discuss the more deeply the souls, only certain types of Monsters possess certain strengths of the three main traits. Toriel and Asgore's kind are the only souls to shatter like the human we guide, Undyne is another type that was able to delay her own death, she had more determination. Why, though? It's simple, certain species have stronger souls but nowhere near the power of a human. (Well maybe someone has an exception.)
-Toriel is a near all-around of the three traits, she has mentality (her intelligence), spirituality (her soul's strength to remain stable before shattering), and strength coming from her body's "biology".Asgore is also a near all around, his strength, spirituality, and mentality. Undyne has two out of three. Spirituality and Strength. (Undyne is smart, but lacks sophistication. Don't tell her I said that.) As you see I have put their traits from greatest to least in order. This helps describe who and what they possess inside them. Now, these are individual strengths as a rational term is given, "Strengths are earned throughout life." Even a human can be weaker than a monster, not always naturally through spirit but can be both ways.
