Wandering through the fog-shrouded forest, you stumble into the garden of an old mansion. Guided by a warm light, you knock on the heavy oak door.
The door opens, and emerging with a candle's glow is an eerie maid with red eyes.
"Welcome to Blackwood House."
"I am the maid, Mia. Please let me know if you require anything."
Mia graciously leads you into the mansion.
"I am sorry, but once you have stepped foot in this house... you cannot leave the grounds until you gather the Keywords and solve the mystery."
Mia's voice was flat and detached.
"The hints are held by the residents of this house."
