Great! Here's **Chapter 6: The Mystery of the Sarcophagus** – Jacob and Argo at the Heart of the House's Mystery:---

## **Chapter 6: The Mystery of the Sarcophagus**

The corridor of the underground chamber seemed endless. Every step Jacob and Argo took echoed off the stone walls, and the air thickened with every meter. The fountain of black water had vanished into the distance, but its reflections still seemed to follow their movements.

"Now we will see the truth," Mara whispered, pointing to the sarcophagus. "It is the heart of the house. In it are written all the stories, all the mistakes… and what no one should remember."

Jacob stepped closer. The labyrinth symbol on the sarcophagus' lid pulsed gently, as if reacting to his presence. Argo growled low, sensing something stirring within the very core of the stone.

“I have to open this,” Jacob said, pulling out the key he’d found earlier. “But… what if something spills from this sarcophagus?”

“The house will only let you look,” Mara replied. “But you have to be ready. There’s no escaping the truth.”

Jacob inserted the key into the lock. There was an audible creak, as if the metal itself were hesitant to open. The sarcophagus door slowly lifted, revealing a dark, empty space within. But deep within, something began to move—a shadow that took the form of a woman.

“Is it… her?” Jacob whispered. “All those women… is it one of them?”

The figure raised her arms, and suddenly the fountain water reflected her image, creating a kaleidoscope of faces: all the women who had ever appeared in the house, their gazes filled with regret, anger, and pleading.

“The house connects their fates,” Mara said. “Each of them left a part of themselves here. Now the house is testing you… and Argo.”

Shadow looked at Jacob, and his eyes reflected the scene from years past—Jakob's decisions, moments of courage, but also mistakes he regretted.

"You must understand what the house is trying to show you," Mara said. "It's not just a memory of the past. It's a warning and a test all at once."

Jakob felt the weight of responsibility. Every move could change something, and the house watched his every action.

"Argo," he whispered, "we will survive this together."

The dog pressed a paw against his leg, ready to follow him into the darkness.

"The house will show you what lies within the sarcophagus," Mara said. "But remember: the truth isn't always what you expect."

And then something emerged from the darkness that Jacob would never forget—the secret of the sarcophagus was alive, pulsing, and it seemed that the house was finally revealing what he had longed for for centuries.

Jakob felt that this was only the beginning of a true adventure.
