For nearly four hours, Marcus and his companions continuously attacked the barrier surrounding the sewer fortress.
The place was incredibly sturdy, having hundreds of protective enchantments and an immense quantity of mana to power its defenses.
Still, under the assault of eleven high level individuals that were nearly as strong as possible for their levels, it eventually reached its limit.
With a sound like glass shattering, the final barrier broke apart and the enormous structure could no longer keep intruders out.
After everyone came back together at the entrance, Marcus went about disabling a few traps that were meant as a last resort to prevent outsiders from entering.
"And there we go." Marcus said once he disabled the final trap.
He then placed his hands on the large double doors and pushed them open.
They spread out seamlessly, and not a single squeak or creak could be heard despite how ancient this compound was.
"I was expecting something truly terrifying to be waiting for us, but it's just an empty hallway."
Mrazivý had been ready with her Dragon Eyes already glowing. Naturally every member of their party had been anticipating that some sort of guardian would intercept them the moment they broke in.
Except all that they found was a large metal hallway with several doors leading into a multitude of rooms.
"Lilia, would you do the honors?" Marcus asked.
Nodding her head, she walked into the large corridor and placed her hands on the ground.
Her detection magic was more accurate than anyone else's so now that the enchantments cloaking the outside of the fortress were disabled, she searched the area again.
"Every room but a large central chamber appears to be abandoned. There are all manner of tools and materials in them though. Some of them are pretty ghastly." Lilia said, looking a bit sick.
She had uncovered several rooms that had dissected and mutilated bodies, piles of bones, and even a few living animals in cages that she could only surmise were being subjected to all manner of cruel experiments.
"Ahem! Are you just going to keep ignoring us to continue working."
Marcus wanted to see what sort of reaction the Revenant Witch before them would have to being called out to. It was possible that her mind was so far gone that she could only continue to focus on the experiments she was fixated on.
However, this assumption proved to be untrue as the Witch put down her tools and the bodies she was enchanting with necromancy.
She then turned around and faced the trespasser that had broken into her sanctuary.
A vestige of the beauty she must have had in life still lingered despite her skin having gray and rotted in places, her hair having become a muted brown that looked like it would crumble to dust if touched, and her eyes being clouded over and almost pure white except for their burning red irises.
The robes she was wearing were clearly those of a high-ranking mage and reminded Marcus of the garments that the archimages of Borealia wore.
Undoubtedly, she had been someone important before the tragedy that had befallen Houten a little more than three centuries ago.
"Why won't you die already you annoying pests? Gah! You're interrupting my worked and have ruined everything!"
The Revenant Witch swung her left arm behind her and shattered several glass containers on the laboratory table be in a manic fit.
While she still retained some intelligence and fragments of her personality, she had clearly gone insane.
"Do you think you can do anything for her?" Mrazivý whispered to Marcus. She had seen him turn Alyna from a wraith into a spirit and save her from the burden of undeath.
"No, her mind and soul are probably too far gone. Even if I did return her sanity and made her a spirit, I doubt she would be able to continue on once she realized the weight of everything she has done."
Marcus understood why Mrazivý wanted him to try and bring back this woman's rationality. She would likely know what had occurred all those years ago when Houten's king at the time turned this city into a necropolis.
Unfortunately, this was far different than when he assisted the undead controlling the Chelmer Resort from the shadows. All of them had retained most of their mental faculties and had not let becoming undead eat away at their souls.
It was only because of their strong force of wills and the skills that they had obtained using the Personal Status unique skill that allowed them to avoid being corrupted.
The same could not be said for the Witch before them. She was unhinged and had delved into some of the darkest necromantic arts. There was nothing but a true monster left.
