Cordelia: As you all know, I made this au called: Harmonytale. The crystal keeps the balance between Humans and Monsters, if one was to break the crystal, then war would have broke up. But they was being guarded by the royal siblings (Not by blood, more of a sister/brother figures)

Cordelia: Here what I mean. Both mages and monsters made Six Crystal to keep the balance between Human and Monster, each crystal are special.

Cordelia: The Six-pointed Star crystal (Magic Crystal) was made from a Determination Soul, a Perseverance Soul, and a Monster Soul.

Cordelia: The Balloon Crystal (Laughter Crystal) was made from: a Patience Soul, a Determination Soul, and a Monster Soul

Cordelia: The Apple Crystal (Honesty Crystal) was made from: a Integrity Soul and a Monster Soul.

Cordelia: The Lightning Bolt Crystal (Loyalty Crystal) was made from: a Bravery Soul, a Justice Soul, a Determination Soul, and a Monster Soul.

Cordelia: The Diamond Crystal (Generosity Crystal) was made from: a Justice Soul, a Patience Soul, a Perseverance Soul, and a Monster Soul.

Cordelia: While the Butterfly Crystal (Kindness Crystal) was made from: a Kindness Soul and a Monster Soul.

Cordelia: So The Determination Soul is rare and only Frisk and Chara have them. But what if some of the mages have a Determination Soul but over time they become rare.

Cordelia: So, onto the reader family

Cordelia: Y/n and his family (He still have a papyrus but I add more siblings siblings to spice things up).

Cordelia: So Y/n Family are the human version of Gaster (Father), Sans (You), and Papyrus (Younger Brother). Y/n will have a Mother and two older siblings, and a younger sibling.

Cordelia: Each of y/n siblings plus y/n himself have jobs (Even through y/n is lazy, he still do this job). Mallory is a Doctor, Markus is a Librarian, Y/n (Sans) is a Famous Fashion Designer, Callum (Papyrus) is a chef, Seraphina is still in highschool.

Cordelia: Y/n Parents are: A Scientist (Father) and a School Nurse (Mother).

Cordelia: Each of the L/n Siblings live alone (Expect Callum and Seraphina, they still live with your father and mother). Mallory is married and living with her husband in a two story house (She has three kids, two girls and one boy). Markus is also married and living with his transgender wife in a three story house (He has two kids, both girls). Y/n is single and living in a Mansion (was going to be a two story house with five rooms and two bathrooms, but have to change it)

Cordelia: Callum, Seraphina, and your parents live in a Three story house. There were four bedrooms upstairs aka Your, Seraphina, Mallory, and Callum rooms. While there were three downstairs aka Your Parents Room, Malcolm Room, and a Studio Room (for you).

Cordelia: But since you moved out, they turn the room into a guest bedroom if any of their grandkids stayed over.

Cordelia: Anyways, Y/n have five friends. Three girls and two guys. The two girls are dating (Named: Katelyn and Cassidy), one is Pansexual (Named: Kimberly), and two guys (Named: Jacob and Carlos)

Cordelia: Katelyn and Cassidy are dating, Kimberly is dating gender-neutral person, Jacob is dating an Non-binary Person, while Carlos is dating an transgender person.

Cordelia: Monster and Mage made six crystals to keep the balance between Human and Monster. But since the crystal was made by the ancestors, the crystal was starting to get old. But the ancestors put a spell on them, so when six kids are born with any of the traits of the crystal. The crystal will fuse into their soul.

Cordelia: But something went wrong when the crystal found their host, it altered the host's soul traits. Making the Host have dual-traited soul.

Cordelia: If you don't know what a dual-traited soul is, go to the glitchtale wiki to know more.

Cordelia: So for Example, take Kimberly. She has the Determination Soul Trait, but since she is the host of the Six-pointed Star Crystal (Magic Crystal), the crystal altered her soul to be Determination and Perseverance.

Cordelia: But her Determination Soul Trait isn't as powerful as Frisk or Chara. She can do basic magic with it.

Cordelia: Also this mixing glitchtale as well. Since it gives me more abilities.

Cordelia: Plus the only humans with monsters soul are Y/n Father, himself, and his younger brother (it a white outline at is visible to the eye.)

Cordelia: But Katelyn and Y/n are special cases, Katelyn already has a dual-traited soul being Bravery and Justice. While Y/n have a Perseverance Soul Trait with a Monster Soul outline.

Cordelia: Now the crystal fuse with the six aka: Kimberly (Magic Crystal), Jacob (Laughter Crystal), Cassidy (Honesty Crystal), Katelyn (Loyalty Crystal), Y/n (Generosity Crystal), and Carlos (Kindness Crystal.)

Cordia: When they was born, the crystals affected them with there powers.

Cordelia: So when Y/n and his friends was showing there souls, everyone was shock on mostly everyone except Cassidy and Carlos.

Cordelia: No one knows how that is possible for y/n to have four different soul traits (if you count the monster soul outline as one.) while Katelyn was born with three soul traits, so y/n father calls it: quad-traited soul for y/n and Tri-traited soul for Katelyn.

Cordelia: But after some research everyone now know, it was the crystals at alter Y/n, Katelyn, Cassidy, Kimberly, Jacob, and Carlos soul traits.

Cordelia: So when the ancestors made the crystal they chose two soul siblings (One Monster and One Human) to be the ruler of their town and to keep the crystal safe until they find a host (The mages gave the soul siblings two necklaces (a Sun Crystal Necklace and the Moon Crystal Necklace). The Moon Crystal Necklace affected the human sleep schedule. Now the new royals are distant cousins.

Cordelia: Also Asgore and Toriel ain't royalty in Harmonytale but normal civilian who adopted three humans and has a biological son (Kris, Chara, Frisk, and Asriel) (Yes, I know Kris is from deltarune, but he still in this book and the only au with a Kris.)
