Sarah Umpid (Comprehensive Gerosha)

Sarah "Meshaluta" Umpid is a ghost-witch in Gerosha universe, and is the titular villain of the Meshalutian Trilogy. Her single-minded obsession is to use natural disasters to kill off members of the Rintel family and bring about her own resurrection. From there, she plans to bring about the apocalypse through her cult followers.

History
Sarah was born around the time of the Marlquaan incident that sent the Gray Champion into the 21st century. The Marlquaan gifted her with specific powers that she could only fully unlock in the event of her death, as her spirit would remain locked in the Marlquaan unless certain conditions could be met which would free her spirit from it.

Throughout her life, she developed a morbid fascination with the occult and began practicing sorcery. She also became fascinated by mathematics, particularly with the nature of logarithms. She developed a theory that she would one day begin killing many souls for several years, with the average number of deaths over the time of the spree equaling an average of 30 victims every 11 years. This number is relatively similar to the natural logarithm.

When she had a falling out of friendship the aristocratic Angela Rintolin, she turned to cursing Angela's family. A feud over the affections of Thomas Quitttledon led to the entirety of Angela's family plotting to get rid of Sarah. They finally succeeded to trap her inside her own house. They lit wicks and laced the interior of her house with gunpowder. As the house exploded and caught fire, Sarah "Meshaluta" Umpid screamed out her last words:

And furthermore, to bring them tears; Thirty deaths, eleven years! Average shall this number be; Now throughout eternity!

Be it family, or their friends; See the dream! And bring their ends!!!

Nature of the Meshalutian Curse
Systematically, all of the original family unit of Rintolins responsible for Meshaluta's death would in turn die a tragic death themselves, especially fire-related deaths. She did not wish to limit the curse to the family unit immediately responsible for her murder; she extended it to all blood relatives, close friends, and anyone who had exchanged bodily fluids with a Rintolin. After Zechariah Rintolin changed his name to Robert Rintel, the rest of the Rintolins were completely extinguished and the curse evolved to target Rintels. Variations of the curse have various levels of determination for a target, which are determined based on an algorithm of Rintel connection:

Chance of death
Note: Even though the algorithm makes it difficult for Meshaluta to kill Trisha Montoya by the rules of the Rintel curse, this doesn't stop her from personally targeting Trisha due to her fear that Trisha might protect the Rintels.

Campaigns before and during Hurricane Nekoda
Her vengeance was spread to the family and friends of the Rintel family, when that family's patriarch changed his last name and forsook the Rintolins entirely. Meshaluta quickly destroyed the Rintolins from beyond the grave, by employing natural disasters and fires to her advantage. However, she found it difficult to extend this curse effectively to the Rintels. Even so, numerous Rintels began dying in strange accidents throughout the following centuries. One recorded example was a Rintel that died in the fires of Peshtigo, Wisconsin. Her sadistic villainy did result in a small cult following, which included several witch disciples and even the eerie Honeybee Samuel. Upon their deaths, Meshaluta's disciples often found themselves serving purposes related to her grand scheme to set the average annual Rintel death toll to the natural logarithm. Her plan involves the deaths of several Rintels, but the one marked for death by her in the Nekoda Campaign is Mandy.

Applestream campaign
When Dewey accidentally dies in Mandy's place, Meshaluta's power is weakened. However, she tries to compensate by murdering some Rintels in South Dakota. This leads to Trisha Montoya being contaminated with Rintel blood, and to Meshaluta developing a personal vendetta against Trisha in addition to her plot against the Rintels. She marks Allison Rintel as her next victim, and succeeds. However, she loses Honeybee Samuel when he fails to kill Trisha and Jared.

Boston campaign and demise
She decides to localize her assault to the last remaining Rintels in Massachusetts, close to where she died, as her defeat in Colorado leaves her too weak to kill Rintels elsewhere. Her disciples kidnap everyone in Carla Rintel's family save for Carla herself, who teams up with Cassie and a rebellious classmate of hers named Keilah to rescue her family. When the disciple witches fail to make the Rintels into a sacrifice, Cassie destroys Meshaluta's power forever. The symbols of the secant function, Mt. Applestream, and the natural logarithm form as white lights over a pond nearby, and re-shape and combine themselves into a Calvary Cross and hill. This symbolizes the ultimate lifting of the curse and the end of Meshaluta.

Fears
Meshaluta despises certain sacraments, such as baptism, due to their religious significance and the invocation of a spirit more powerful than her own. When she makes special claim to Trisha, it is Trisha's specific decision to be baptized that exorcises Meshaluta out of her.

Trisha also learns that Meshaluta's power is weakened in the presence of gunpowder, hence she wears a necklace with a spent toy rocket cartridge on it. This is because of the gunpowder the Rintolins used in Meshaluta's execution.

Carla Rintel learns in LN that Meshaluta's followers grow desperate to make up the numbers and resurrect Meshaluta after her power is weakened through failure to kill certain targets. While Meshaluta succeeds to kill Allison Rintel, she failed to also kill Trisha and Jared. She lost Honeybee Samuel in the process of her failure to personally kill the both of them, and in her lack of employment of a significant storm system to aid her. She was also weakened by her failure to kill Mandy Rintel, as Dewey received the death blow of Hurricane Nekoda in Mandy's place.

On top of this, she stalks Tim and Cassie out of fear that Cassie may one day be her undoing. This proves to be a self-fulfilling prophecy when Cassie offers to sacrifice herself to destroy Meshaluta's power forever.

Dreams
Meshaluta enjoys taunting her victims by sending at least one member of every Rintel family unit with a marked member in it a prophetic dream. These dreams foretell events that she intends to have happen soon to the marked member's family. Sometimes, she makes appearances in the dreams herself. At other times, she has one of her minions appear in the dream in her stead.

When she develops a particular personal hatred for Trisha, she sends Trisha multiple disturbing dreams and visions. Meshaluta herself appears in Eva's dream and warns Eva of the effects on Murian Township to be expected from the union of a magnetic storm with Hurricane Nekoda. She also sends similar dreams to Carla Rintel, while targeting Carla's entire family unit. She sends her minion Sanction Harlem to recall the details of her own execution by hanging and to recite a riddle poem in Jared Rintel's dream.

Appearance
Meshaluta appears to victims as an old witch with green, metallic skin. Her eyes glow red and her face is often expressionless or angry. She wears a hood and cloak that are both a shiny magenta silk color, along with brown shoes and a rope for a belt.

Inspiration
The character of Meshaluta was inspired by Matilda Dixon in the 2003 film Darkness Falls. Her haunting of Trisha and her strong aversion to gunpowder are also inspired by Samara's antics in The Ring Two. Her green skin is inspired by that of the Wicked Witch of the West. Her cloak and cowl outfit is inspired by Emperor Palpatine. It is recolored magenta in keeping with her favorite color, as well as to symbolize her connection with the magnetic storm that merges with Hurricane Nekoda. Purple/Magenta auras sometimes surround objects that are affected by Nekoda.
