lead me to the mansion

The last descendants of Arlott have died and left the wife with the family's surname. A mansion passed through generations, yet she was unaware of this mansion's existence. Her husband died in an odd and despicable way as if he knew his doomsday, was it a disease that corrupted him or was it the works of someone? Lilith is to unravel everything by what her husband had left for her. The mansion.

Stuck in the forgotten era, she came to a stop before the wooden door. It was loose and the door is barely hinged, the knob rattled open. In her sight, stood a 'person' ? ? her hands waver in fear, her scream is just behind her throat, she felt her knees give up. The clock ticked slowly with every second felt eternity. "It was you two" she exclaimed.
