Dahlia Gillespie

Dahlia Gillespie is the main villain in the video game Silent Hill. She is a leader of the cult known as The Order, situated in the notheastern town of Silent Hill. For the bulk of the game, she appears to be a helpful character, helping Harry Mason, the game's protagonist, fight Alessa, the mysterious young woman Harry sees throughout the town.

Cult Activities
Dahlia grew up in Silent Hill, and eventually became the head of the Order sect known as the Sect of the Holy Woman. She may have been involved in the mysterious deaths of several people involved in developing Silent Hill into a resort town back in the 1960s. She also started a drug trade, selling a hallucinogen to the tourists, made from a local plant named White Claudia, that was also used in the cult's rituals. She was assisted in this by Dr. Michael Kaufmann, the director of Alchemilla Hospital, whose level of cult involvement and activity is unknown. This led to Dahlia's involvement in the death of the anti-drug mayor and the narcotics officer Gucci. But Dahlia's supreme goal was to bring her God into this world and bring paradise on Earth, but her real interest was in gaining personal power. She attempted to impregnate several young girls with the god, but none of them could withstand the trauma involved in the impregnation process.

Alessa
Dahlia then found out that her seven year old daughter Alessa had vast mental powers. Dahlia and the cult proceeded to perform the impregnation ritual on Alessa, which involved setting the girl on fire, in an upstairs room in the Gillespie house. She had managed to bind Alessa's power with a mystical device called the Flauros, but she didn't count on Alessa drawing in an outsider named Travis Grady to help her fight back. Travis unwittingly helped her release her powers, and Alessa foiled the cult's plans by splitting her soul in half, shaped it into an infant, and placed it on the side of the road, where the childless Harry Mason and his dying wife found her and named her Cheryl, raising her as their own. Although the god was successfully impregnated in Alessa, the half of her soul left was not powerful enough to give birth to it. Dahlia cast a spell, keeping Alessa alive and in extreme pain, not allowing her burns to heal. Her intention was for the other half to subconsciously feel Alessa's pain, and come back to Silent Hill, where the soul would be reunited.

Seven Years of Waiting
Dahlia had Alessa placed in secret room in the sub-basement of Alchemilla and kept under the watchful eye of Kaufmann. Alessa's intense suffering caused her to slip into a coma, but her subconscious self was still active. Essentially, Dahlia's spell had caused Alessa to plummet into a nightmare state, which was populated by monsters representing her fears and anxieties. The dormant God inside of her fed off this fear and suffering, allowing it to develop.

Harry and Cheryl Arrive
Seven years after the ritual, Alessa's suffering causes Cheryl to subconsciously choose Silent Hill as the vacation spot they would visit, something which they had done together since Mrs. Mason had died four years previously. As they drew close to the town, Alessa awakened and sent out an astral projection of her soul. Near the town lines, while Cheryl is asleep, she runs into the road, causing Harry to crash the car, knocking himself out. When he awakes, Cheryl has disappeared and he is in Silent Hill's Otherworld, which is manifesting Alessa's nightmare. In fact, Cheryl has now merged with the half soul of Alessa, and pretty much ceased to exist as an independent entity. She begins rapidly maturing to Alessa's current physical age of fourteen. Using her powers, Alessa forms a scheme to destroy herself, the town, and the God by spreading a magical crest, known as the Seal of Metatron, throughout the Otherworld town to make up one large crest, with several that were larger than the others placed in key locations. Cheryl's return and bonding with Alessa catches Dahlia's attention, but she can't finish the ritual until Alessa's soul is brought back to her body. She also cannot enter the dark side of Alessa's Otherworld, known as the Otherside, where Alessa is carrying out her plan. Dahlia needed someone else to help her, and ultimately settles on Harry, whom Alessa moves between the light and dark worlds in order to keep her beloved "father" from dying. Dahlia proceeds to trick Harry into assisting in her scheme.

Dahlia's Machinations
Dahlia leaves clues around Silent Hill directing Harry to the key locations, including the school, the hospital, and the amusement park. She even places Cheryl's voice calling for help and her father on a telephone near Harry and even places a similar voice along with an ominous image of Cheryl on a television screen he passes. She meets Harry in Balkan Church and points him toward the hospital. She also gives him the Flauros, which she told Harry would contain Alessa's evil. She meets with him several more times and at the last one, she tells Harry that Alessa is a demon in a child's form and will make Cheryl into a sacrifice and set the Otherworld loose if she completes the seals, which Dahlia calls the Mark of Samael, an old name for the devil. He doesn't fully trust her, but has nothing else to go on. Harry fails to stop Alessa from completing the first several seals, but arrives at the amusment park ahead of her, and confronts her, demanding Cheryl back. Alessa pushes him away with her powers, but the Flauros activates itself and traps her. Dahlia arrives, and Alessa's Otherworld loses its cohesion and collapses into a mixture of the different locations, referred to as "Nowhere." It is here, in a transfigured form of the Gillespie household, that Dahlia prepares to complete the ritual.

The Birth of the God and the Death of Dahlia
Harry arrives just as the soul is reunited with the body, and confronts Dahlia. She then proceeds to explain most, but not all, of what has been going on. The soul is restored to Alessa's charred, bandaged body. They both disasppear and are replaced, by the God, who has manifested as Alessa's image of her, a woman in shining robes. Kaufmann unexpectedly walks in after the God is born. Blaming dahlia and the Order for his presence in the fog world and then the Otherworld, he wounds Dahlia with a pistol and hurls a vial of aglaophotis, a substance used to expel demons, at the God, not fully cognizant of what has just happened. This has an unexpected consequence when it causes the God to transform into Dahlia's image of God, namely that of a winged demon. The God destroys Dahlia with orange lightning and fights with Harry, who destroys him. The God falls to the ground and transforms back into the shining woman. It recreates Alessa into an infant, and hands it to Harry, who is unaware of the woman's true nature. The infant still had the capability of birthing the God.

Legacy
In Silent Hill 3, Father Vincent refers to Dahlia as "that old hag" from seventeen years ago. He also claims that she "brainwashed" Claudia Wolf, the game's antagonist. The Holy Woman sect was destroyed during and not long after the events of the game, a causalty of Dahlia's actions. In Silent Hill 4: The Room, It is revealed that Dahlia, in an act of cooperation with the rival Sect of the Holy Mother, Dahlia told the young orphan Walter Sullivan that performing the aforementioned sect's ritual of birthing, the Ritual of the 21 Sacraments for the Holy Mother, would reunite him with his birth mother, intended as a fail safe in case her plans for Alessa went awry. When Dahlia felt she no longer needed the Holy Mother Sect, she showed Walter his birthplace, at room 302 of South Ashfield Heights, an apartment building in the nearby town of Ashfield. Here, she sabotaged the Holy Mother Sect's plans by telling him that the room was in fact his mother. This led him go on a killing spree as an adult, attempting to commit the twenty-one sacrifices needed to complete the ritual. Several of his victims were important Order priests, which brought down two of the three original sects.

Movie appearance
Dahlia Gillespie appears in the live action movie Silent Hill. Dahlia is part of a fanatical, puritanical sect presided over by her sister, a religious woman named Christabella who later killed her neice Alessa under the belief that she is a witch and a demon child.
