Hallowstale background info:

A world were most of the main cast are human, able to transform into monsters via masks that they wear. And when Frisk falls down, it is nothing but genocide timelines, until Sanse, Flowey, Chara, and a new mysterious soul, figure out a way to stop Frisk, and force a pacifist run, once and for all.

(Quick note, this is a mostly gender-bent universe. I say mostly because this universe is my most inclusive, so some characters are Nonbinary or Trans, but the basic sex of the cis characters are swapped.)

In this world, not only are there Monsters and Humans, but Monster-Humans (M-Hs), and Souls Mages.

M-hs are children born human, with a monster form transformation. When the child turn 5 years old, a package will magically show up at their front door with a mask inside. The mask is a representation of their monster form. When the owner of the mask wears it, they turn into their monster form.

A m-h's soul consists of a monster soul inside of a human soul. The monster form has a longer life span than that of their human form. When an m-h dies in their human form, their mask can be placed on them, forcing their body to turn into a monster as their human soul shatters, leaving that m-h to fully become a monster (a process known as monstercation). When their monster soul is killed, the m-h will simply dust as, to reach the monster soul, their human soul must also be peirced. Some m-hs can have two human soul traits, and, very rarely, three soul traits.

The masks of the m-hs are indestructible and can't be lost. Upon the mask being more than 50 feet away from the owner, it will magically appear near the owner.

A m-h can cast magic. However, they can only cast magic in their monster forms.

Soul mages (SMs) are humans who have access to their soul trait's magic. Soul mages are fairly rare and commonly infertile.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Birth Rates:

Human x Human = Human (99%), M-H (1%)

Human x Monster = M-H (50%), Monster (50%)

Monster x Monster = Monster (100%)

M-H (monster) x Human = M-H (50%), Monster (49%), SM(1%)

M-H (monster) x Monster = Monster (99%), SM (1%)

M-H (human) x Human = Human (74%), M-H (25%), SM (1%)

M-H (human) x Monster = Monster (74%), M-H (25%), SM (1%)

M-H (m) x M-H (m) = Monster (98%), SM (2%)

M-H (h) x M-H (h) = Monster (49%), M-H (49%), SM (2%)

M-H (m) x M-H (h) = M-H (98%), SM (2%)

There have been no documentation of any births in relation to a soul mage parent.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Mt. Ebott is encircled by a rural community that houses a cult, known as the Purity of Soul. It was founded by soul mages from each of the attributes. The cult believes that monsters and m-hs are impure, inferior, and have no right to live in their perfect world.

42 years ago, before Frisk fell down, the followers of Purity of Soul (PoS) enacted a monster massacre. They light buildings aflame, they killed monsters, m-hs, and human sympathizers. Torel and his wife Asgore gathered and led the survivors to one of the entrances of Mt. Ebott. The Soul Mage leaders of the PoS created a barrier around the two entrances into Mt. Ebott, trapping everyone inside. The only way out is to use 7 Soul Mages, each one being a different soul type, to break the barrier. The PoS, believing the 'tainted' to soon starve in the mountain, leave to go about their daily lives. However, there were already animal-like monster creatures living within the intricate cave systems, along with the River Person. They help the survivors build a new home in the mountain. The survivors also appointed Torel and Asgore, the leaders of the Underground.

A year or two later, as some children in the community received monster masks, the PoS was horrified to learn that m-hs could be born of two human parents. And even more, some unknowing monster from elsewhere on the globe would move in for cheap housing and relative closeness to the city while remaining suburban. A ruling was stated that any monster is to be captured, m-h children are to be brought forth to the council to be "educated," and anyone who tries to hide either will be killed. In reality, all are killed. Parents who wind up having m-h children do their best to hide that truth or flee to one of the Mt. Ebott entrances and live in the Underground. Some of those m-h children will grow up to be brainwashed into despising their monster half. Moving away quickly became futile, as rumors would spread that the family are sympathizers and sentenced to death.

Those who were sentenced to death were paraded up to the top of Mt. Ebott (right before the Ruins entrance). Everyone else in the community is required to attend and watch. They would then kill the guilty party, dumping their remains down the hole.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The two laws were written as follows:

- Report any monster-humans so they can be educated and get help.

- Any humans caught harboring monster-humans, or monsters from outside the community, will be given the highest form of punishment: death by execution.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I think that's it for now.

More stories will be coming out, including character personal stories/information, and artwork.

There will be a special story coming out that would be this au's Gaster (and later Sanse's) journal.

Error by loverofpiggies

[forgettable-au]

Sans do you ever feel that something might be missing?

Maybe he felt like that at some point, maybe for a long time. In the present, I think he's made some kind of peace with it.

Also, I really like the ask blog format, but I don't really mean this to be an ask blog.

So when writing questions, try to refer them to me instead of the characters. That way, they don't have to break the fourth wall lmao. I really wanted to answer this one tho
