The entry room, once they descended, was smaller and more deliberate than Xavier expected — a square antechamber carved directly from the bedrock, walls lined with faded murals depicting a war he didn't recognize, armies clashing beneath a sky rendered in flaking gold leaf. A single corridor led onward from the far wall, sloping steadily downward into darkness.
"This place is old," Bruce said, running a hand along one mural, careful not to disturb the flaking paint. "Older than anything we've seen so far. Look at the armor styles... this predates House Windstrom's records by a wide margin."
"Great. Ancient and unmapped," Xavier said. "My favorite combination."
Bruce lingered a moment longer than either of them expected, tracing the mural's painted armies with real fascination rather than his usual clipped professional interest. "There's a whole story here, if you follow the wall all the way around. Look. It starts with this column of soldiers marching in from the left. Earth-colored banners. Then it shifts here, into this section with the fire, an actual battle, mid-swing, painted mid-motion. Then wind, carrying off all this ash after everything's burned. And then, at the end, water. Mourners, a funeral rite, the whole thing closing on grief rather than victory."
"You got all that from one glance?" Stephan asked, squinting at what looked, to him, like a badly faded smear of gold and red.
"I got it from actually looking," Bruce said, not unkindly. "Someone spent a very long time telling this story on a wall nobody was ever supposed to see, let alone examine. Feels worth remembering, is all I'm saying."
Xavier filed the observation away without quite knowing why it mattered yet, more focused on the corridor ahead than the history behind them, and they pressed on down it, torchlight throwing long, shifting shadows across walls that grew progressively less decorated and more functional the deeper they went — smooth stone giving way to rough-hewn rock, murals giving way to nothing at all, the temperature dropping steadily with every step. Small alcoves lined the passage at irregular intervals, each holding a single, ancient funeral urn, undisturbed, gathering centuries of dust.
"Crypts..." Stephan said, peering into one. "Actual, real crypts. This is exactly as spooky as advertised."
"Don't touch them," Bruce said immediately.
"I wasn't going to touch them."
"You were absolutely going to touch them."
"I was going to touch one of them. Singular. In a respectful, scholarly way."
"For what it's worth," Stephan added, peering into another passing alcove, "I've decided I like the murder-history vibes better than actual murder. If we could keep it that way for another hour or two, I'd appreciate it."
"I'll pass the request along to whatever's down here," Bruce said dryly.
They passed perhaps thirty such alcoves before the corridor widened into a small landing, and Xavier paused there, holding the torch up to a row of urns that looked, unlike the others, deliberately arranged rather than simply placed — grouped in threes, each trio bearing the same faded symbol etched into the stone beneath it. "Families, maybe?" he said. "Whoever this was, they buried their dead in groups. That's not how you treat soldiers, is it?. More so how you treat people who mattered to each other."
"That's oddly thoughtful of you," Bruce said.
"I contain multitudes," Xavier said, echoing a phrase he'd apparently already decided was his going forward, and moved on before either of them could comment further.
The corridor bent twice more before opening into a wider passage, the air here carrying a faint, dry, papery smell that Xavier's instincts flagged as bad news well before his conscious mind caught up with why — old bone, disturbed dust, the specific stillness of a space that had been sealed away from fresh air for a very long time. Ahead, past the passage's final bend, flickering torchlight spilled out from what looked like a proper chamber.
"Someone's already down here," Xavier said quietly, ice already gathering reflexively along one hand before he caught himself and let flame replace it instead, more in line with what actually worked best against whatever they were about to find. "Or something."
"Or it's just old magic keeping the place lit?" Bruce offered, though he didn't sound entirely convinced of it himself. "Some wards are built to last centuries without upkeep. Wouldn't be the strangest thing we've found underground."
"I'd love for that to be the answer," Stephan said, easing Ember another inch out of its sheath. "I would love, so much, for that to be the boring, correct answer."
Bruce drew his hammer. Stephan's hand found Ember's hilt fully. Nobody said anything else as they crept the final stretch toward the light, the papery smell growing stronger with every step, boots deliberately soft against old stone, three sets of eyes straining against torchlight that seemed to flicker just slightly wrong, throwing shadows that didn't quite match the shapes that should have been casting them.
The murals along this stretch of wall had changed too, Xavier noticed as they crept past — no longer soldiers or funeral rites, but tall, robed figures standing apart from the armies entirely, painted with a strange, deliberate reverence that set them apart from everything else in the room. He didn't have time to look closer, and told himself, not entirely convincingly, that it probably didn't matter yet.
Xavier kept one hand near his sword and the other ready to call flame at the first hint of trouble, heart loud enough in his own ears that he half expected it to give them away before anything else did. The corridor's final stretch felt considerably longer than its actual distance, every step measured and deliberate, the three of them moving as close to silently as three people carrying that much metal reasonably could.
"If this is another spooky hallway of paintings," Stephan whispered, "I would like it on record that I am personally opposed to any more art appreciation today."
"Noted," Bruce whispered back. "Overruled, if it comes to it. But noted."
Nobody spoke after that. Xavier could hear his own pulse now, steady and much too loud, and found himself counting his own footsteps just to have something to focus on besides the growing, wordless certainty that whatever waited past the light was going to matter a great deal more than anything they'd found so far. The passage opened at last into a room considerably larger than anything they'd passed through so far.
And considerably less empty.
