Chapter 18: Chapter 18: THE AVATAR

The chamber beyond the door was surprisingly vast, much more so than the hallway had hinted.

The ceiling disappeared into the darkness above, leaving a sense of mystery. The space stretched out in every direction, designed more to impress its occupant than to welcome visitors. It was adorned and furnished in a way suited for a palace. The stone here, though similar in light colour to the pristine corridor, felt older- smooth and worn, shaped by something beyond just the passage of time. The miasma was different too: thicker and more deliberate, as if it had been carefully cultivated over decades by something that knew exactly what it was doing.

An orb rested gently on a raised platform in the centre of the chamber. It wasn’t glowing brightly; rather, it seemed as if the room’s light was subtly drawn toward it. The atmosphere around it felt dense and tangible, carrying a quiet tension- like a heartbeat hanging in the air or a breath held in anticipation.

The lich was already patiently waiting when they entered, standing still in the middle of the chamber. It didn’t rush or show any immediate threat, just there, fully aware of their arrival, as if it had been waiting for just the right moment.

It looked at them with a calm, steady gaze. The way it paid attention to them didn’t feel surprising at all, but rather familiar and reassuring.

"Further than the others," it said. Its voice had a calm, aged quality, as if it had been around long enough to find most things just mildly interesting rather than threatening. It felt ancient, unhurried, and totally at ease. "The woman is extraordinary. I suspected as much from the boundary."

Theresa remained silent as she focused on the chamber. Dominic could tell by her posture, the way her eyes flicked around, and what she was thinking about.

"You’ve been down here for a long time," Dominic said.

"Yes, I have, almost too long." It replied, and he looked at them with a calm, patient gaze, as if he had already made up his mind and was waiting for them to decide, creating a sense of understanding and gentle anticipation.

"You understand you are standing in the most concentrated point of everything I am. You’re making it this far simply because I’ve allowed it. Now, unfortunately, you must die, but don’t worry, I’ll make sure to put your bodies to good use, especially yours." It said, looking at Theresa.

The orb sat behind it on a platform, the chamber encircling them. The miasma pushes at the edges of the space, with a purpose and a weight that hadn’t been there in the corridor outside.

It’s not protecting the orb.

It’s waiting for something truly worth fighting for to come to it.

And then, it moved fast.

***

The first strike came for Theresa.

She was already moving when it arrived, feeling the surge of energy rush through her body before she even made a conscious decision. Her frame effortlessly absorbed the force of contact, a testament to someone who had spent a lifetime understanding her body’s capabilities and pushing them even further.

She hit the ground. Rolled. Came up.

Dominic felt the bond amplification shift as she recalibrated mid-movement. The physical enhancement in his limbs adjusting, buffs increasing in intensity and something additional threading through from her that she was generating while simultaneously fighting her own side of the chamber. He felt the cost of that in the quality of what came through. She was working. Actually working at a level he hadn’t felt from her before.

He moved into the undead that the lich directed towards him.

All the academy training and hard weeks he’d put in were now coming into play. He wasn’t winning with style, but he was holding his ground and making a difference. The boost from his preparations made the distinction between just getting by and truly making an impact clear. Still, it was obvious in every move that he was still short of what this place demanded. All he could do was hold his position and keep pushing, preventing the lich from using this avenue to reach her.

Theresa was doing something extraordinary across the chamber.

Dominic felt the bond thread strengthen as she pushed herself harder than she ever had before. It wasn’t just power flowing into him, it was her focus, her calm determination, like she was right there beside him even as she fought her own battle.

The lich had the advantage of location. The concentrated miasma, working in tandem with it, and the gravity of the space pressing against their movement, gave it an edge. It understood this space perfectly, with decades of practice using it. It pushed a force into the chamber that made the air feel solid.

She responded by pushing back.

It was a low-grade spell, amplified beyond what its grade would normally allow. The force met the lich’s output in the center of the chamber, holding firm and then pushing back. The lich registered this with the first reaction that wasn’t patience. Something shifted in how it moved- a recalculation. It realised that the woman across the chamber was doing something it hadn’t fully anticipated.

Theresa, between exchanges, was breathing steadily, showing some effort but not gasping. Her face revealed the exertion, and she held herself in a way that wasn’t noticeable when she was operating at a much lower level. She was pushing herself close to her limit for this particular fight, in this particular space.

She kept going without stopping, determined and steady. Dominic pushed through the crowd, the undead gradually thinning as the lich focused more on Theresa. Seizing the opportunity, he hurried across the chamber floor toward the raised platform, aiming for the orb that sat prominently at its heart. Reaching out with quick, confident motion, he swung his sword towards it forcefully, ready for what was next.

The corridor was narrow where Wobbly had wandered.

It slowly wandered through the clean, beautiful rooms, exploring everything with gentle curiosity. It passed through archways, past neatly arranged shelves and sealed containers, and down a side passage that grew narrower as it went, though it didn’t really mind the narrowing.

Light filtered gently from a small gap ahead, where two ancient stones had parted. The light beyond was unlike anything else below, more pristine, more tranquil.

Wobbly glanced at the gap, then confidently went through because it didn’t see physical limitations as obstacles to its plans.

There was a small, sealed room on the other side, with no door and no visible way in except for the hole it had just come through. Right in the center, there’s a smaller orb than the one in the chamber, calmly sitting in the middle of an otherwise space, glowing

Wobbly gazed at it with delight for a moment, then suddenly, it swallowed and ate it, making adorable noises.

The energy from the orb immediately flowed through it, sending a warm glow that charmingly shifted colours in an enchanting display. It cycled through hues it hadn’t seen before, finally settling into a familiar yet more vibrant shade. This made it feel more grounded and alive.

Wobbly sat comfortably in the sealed room, taking this all in and digesting the experience.

***

The core in the middle chamber shattered into pieces as Dominic’s blade made contact.

During the exchange, the lich sensed that something was off. It wasn’t coming from the core in the chamber, but from somewhere else in the building.

And then, quite suddenly, everything came to an end. The lich came undone and gently faded away, screaming in dread and defiance, adding a dramatic and emotional touch to the moment.

The chamber, once filled with its core, was now just a simple room, nothing more.

Theresa looked at him across the chamber, breathing hard but steady. For a split second their eyes met and he felt the bond pulse once, warm, alive, and shared. They had done this together.

The miasma, which had once had a purpose, quickly lost its sense of direction, drifting away as its source vanished. The walls seemed to remember the absence in a way reminiscent of ancient structures that revealed the emptiness of what once surrounded them.

Then, the first stone softly fell from the ceiling.

"Run!" Theresa said.

***

They ran.

The pristine corridor begins to fall apart behind them. The meticulous neatness of the rooms is breaking down as the thing that kept them so tidy is gone. Stones are falling in pieces, the space around them is filling up with belongings left behind, and the bags of loot they couldn’t carry are scattered across a space. Dominic has only been able to grab their original spatial bag out of stubbornness.

A section came down ahead, and Theresa quickly pulled him through the gap before it closed. Then, a section came down behind them, and he gently guided her through before it sealed shut. The structure was stubbornly fighting against their escape just as fiercely as it had fought their arrival, with the collapsing geometry squeezing them into tighter spots with every move they made.

The chimera chamber is quiet now; everything inside has come to a stop, and the movement that once kept them going has vanished along with everything else. They pass through smoothly, without any hesitation.

The alarm systems no longer function—soon, they’ll reach the corridor leading to the mausoleum entrance.

As they go up through the entry, the stone around them begins to shake. The structure seems to give way beneath their feet as they reach the top.

The graveyard above looked peaceful now. They stepped out, breathing heavily into the morning air that felt surprisingly expansive after being inside. The fog around them was beginning to lift, revealing the still shapes of the corpses that had once seemed so alive. The graveyard was settling into a gentle quiet, a rare calm that hadn’t been felt in months, like a long-held breath finally let out, bringing a sense of relief to the whole place.

They stood on the grass, breathing heavily and not speaking immediately.

Then, from the rubble of the collapsed mausoleum section, movement. Then Wobbly burst out through the last of it, looking significantly rounder than before. Its shape had changed, indicating it had gained quite a bit of extra volume from somewhere, but it hadn’t yet figured out how to handle that structurally. Its glow was different too, still using the same frequency as always, but now it felt deeper, more vivid.

It sat on the grass.

It looked at them.

Then it threw up, in whatever sense Wobbly threw up, and everything came out.

Let’s start with the spatial bags first. Four of them gently spilt onto the grass, as if they’d been carried with ease. Following that, the contents came out- probably because Wobbly had also eaten some of them for storage convenience and was now returning everything: weapons in a neat pile, artifacts, sealed containers, gold in amounts that took them a moment to process, personal belongings from earlier visitors- everything from each room along the pristine corridor lay out across the grass outside the graveyard. It seemed to go on longer than either of them had expected.

Dominic stared at the growing pile of weapons, artifacts, gold, and sealed containers.

"Wobbly... you absolute legend," he muttered, half laughing, half in disbelief.

Wobbly’s glow faded to its dimmest, still softly present. It was leaning slightly to one side on the grass before settling into stillness, making tired noises and not moving.

Dominic took a glance at the pile, then turned his eyes to Wobbly, and finally looked towards the collapsed graveyard behind them. He observed how the fog above the boundary wall gradually and evenly lifted, as whatever had been holding it there vanished.

Theresa briefly looked at Wobbly, then they both turned to face each other. A look of surprise flashed across their faces before they burst into laughter, sharing a moment of joy.
