Underground Monster[edit]

Physical Description[edit]

Monsters come in numerous shapes and sizes, although the notable species of monsters include skeletons like Sans and Papyrus, ghosts like Napstablook and Mad Dummy, and Boss Monsters like Toriel and Asgore. Monster SOULs are upside down and wholly white.

A monster's body is mostly made of magic and is attuned to its SOUL. When a monster gets old, they enter a state referred to as having "fallen down." A monster in this state lies immobile and dies shortly afterward. When a monster dies, its body turns into dust. This dust is often spread onto the owner's favorite thing at funerals so that their essence lives on in their possessions. Monsters' bodies and SOULs are closely linked; when a monster dies, its SOUL is lost forever. Boss Monsters are an exception, as their SOULs exist outside their bodies for a few moments before shattering

History[edit]

Long ago humans and monsters lived together in harmony, but one day it was discovered that monsters had the ability to absorb human souls and become frighteningly powerful. Humanity, despite knowing that monsters were too kind and merciful to harm anyone with this power, attacked them out of fear. During the short-lived "War of Humans and Monsters," humanity slaughtered countless monsters, with fallen humans leading the charge, before sealing the rest of them beneath Mt. Ebott, using the magic of 7 human wizards. As thousands of years passed, monsters faded into legends and so did the abilities of fallen humans. Most humans, despite forgetting that monsters exist, are superstitious of Mt. Ebott, since those that climb it never return. That superstition never stopped a handful of children, who ventured up the mountain and fell into the underground, where Monsterkind was still residing. Most of those children were killed and their souls were taken, but eventually, the barrier, that kept Monsterkind sealed underground, was destroyed and a small fallen human helped Monsterkind incorporate themselves into human society.

Society[edit]

Today, monsters are living with the more accepting human civilizations. They interact and form bonds with other humans. They use their magic to help themselves to their friendly humans. They exchange ideas and grow better from it. Monsters are quite open

Underground Monster Names[edit]

Monsters' open-mind views have very little pattern for their names, just like humans. Unlike most races, monsters can be male, female, or genderless as gender has no purpose for reproduction.

Male: Sans, Grillby, Asgore, Papyrus, and Mettaton

Female: Muffet, Toriel, Alphys, and Undyne.

Genderless/Gender Neutral: Woshua, Parsnik, Whimsalot, Napstablook, and Mad Dummy.

At the start of a creature turn that is affected by Karma condition, they take necrotic damage equal to the total number of Karma divided by 5 (rounded up), and Karma is reduced by the amount of damage taken.

If not using a grid, the shield is next to the green soul. It is close enough to prevent another creature from getting between the shield and the green soul but far enough to give the green soul its space.

The green shield is always in the same place relative to the green soul, regardless of where the green soul moves to. At will and not requiring any actions, the green soul can will the shield to move to a different line that the green soul is in the grid, above, or below.
