Theresia is a horror adventure and visual novel developed by WorkJam for the Nintendo DS, released in 2008. The game is divided into two separate campaigns. The first, Dear Emile, follows a young woman named Leanne who wakes in a deadly labyrinth with no recollection of her past. Rescued as a child by a blood-soaked stranger, she must piece together the truth of her imprisonment and find a way to survive. The second campaign, Dear Martel, centers on a doctor who devises a cure for a fever devastating an orphanage in his care. Though the disease is subdued, his treatment gives rise to something considerably more dangerous, and he must confront the consequences of his actions. Together, the two stories explore themes of obsessive love, moral failure, and survival through exploration and narrative discovery.
Leanne, a teenage girl wakes up in a small, dim room with no memories. The only clue is the word Theresia scribbled upon a piece of paper. The first areas of the game instruct the player on the controls, set the atmosphere and introduce the survival aspect. The building is not only the sub-basement of a larger complex, but also riddled with hidden traps. Most doors are locked, barricaded, or blocked by environmental hazards. Leanne discovers she is in an underground prison facility, which stretches over several underground stories and includes waterworks, storage and torture rooms, and unknown crypts. In the upper levels, more of the setting and Leanne's background are revealed: the country is losing the war, and the prison is part of a military installation which includes a testing laboratory, run by a woman named Maylee, who Leanne has seen in flashbacks. She also has flashbacks of a young man named Sacha and a silver-haired woman drenched in blood.
