Blackhill Keep: Heir of the Night
SteamBlackhill Keep: Heir of the Night is a survival horror immersive sim set in a cursed castle.
You have just arrived at the castle atop Blackhill, the ancestral home of the fallen Lemanius family of nobles. Explore the Keep, solve puzzles, and uncover the dark secrets of the Duke of Blackhill.
"Yet even he came to fear death, and in his desperation the Duke turned to dark magic to attain immortality."
Blackhill Keep is a mysterious place filled with secrets to be found and creatures to face. The catacombs of an ancient civilization, the ruins of an old palace, the curse of a Duke. All to be found within.
"Known to locals as "Blackhill Keep", the castle was home to the Lemanius family for centuries until their eventual demise during the 7th age.
The hill on which the castle was built has a rich history, having been the site of many battles and even another castle, centuries before the Lemanius family claimed it. According to locals of Levatsier, some parts of that ancient castle are still standing."
Many decades ago, the Duke of Blackhill performed an unholy ritual to attain immortality. He sacrificed his own kin and servants for the sake of reaching his goal. It was a success, but one of his sons escaped that night, never to return to that accursed castle.
That son was your great-grandfather, and now you have come to Blackhill Keep to claim your inheritance.
"The Duke of Blackhill was unrelenting. Always faithful to his family and dukedom, he was a righteous and pragmatic ruler."
If you run out of health you will promptly wake up in a different part of the castle, having lost some of your items and progress.
"Inside this place lives a mysterious creature that lurks in the shadows. It still stalks the halls of the castle, still hoping to protect the Duke's bloodline.
Perhaps there is a way to communicate with it, or at least manipulate it to your advantage."
Many creatures inhabit the Duke's castle, some are said to live there since the time of the Duke himself.
Some are friendly, others are hostile, and some are just indifferent to your presence.
Together, they form a complex ecosystem inside the castle, each denizen with its own behavior and role in the castle.
