No Direct Openings

They circled the ring's outer edge cautiously, keeping a respectful distance from the roiling, bubbling water, Colm tracking its full shape carefully against his charts.

"...It's continuous," he reported, after nearly an hour of slow, careful circling. "No gaps, no breaks, no natural channel through. The whole ring closes completely, all the way around."

Arista studied the shimmering line stretching in every direction, the water visibly disturbed, steam rising faintly where the heat met open air.

"...This is why," she said quietly, the realization settling in heavy and certain. "This is why the mermaids became isolated for who knows how long now. It's not a barrier someone built. It's not a wall, or a gate, or anything with an obvious door somewhere waiting to be found. It's just... geology. A ring of underwater lava activity that happened to seal an entire people off from the rest of the world, with absolutely no consideration for whether anyone inside actually wanted to stay."

Bram studied the ring's unbroken circumference, genuinely sobered by the scale of it. "...How long has this actually been active?"

"No way to know for certain," Claire said, checking her temperature readings against the ring's apparent stability. "But something this consistent, this evenly distributed, this isn't a recent event. Whatever caused it, it's been running steady for a considerable time."

Nettle considered the ring a moment longer, something faintly amused crossing her expression. "...Realistically, the mermaids themselves were probably only coded in fairly recently."

"Immersion, Nettle," Bram and Arista said, in perfect, unplanned unison.

"Right, right," Nettle said, entirely unbothered, already waving the comment away. "Ancient, isolated civilization, sealed off for centuries. Continuing."

She shook her head slowly. "...An entire civilization, cut off, not by choice, not by conflict. Just by bad geological luck."

"Same as the storm border," Arista said, quiet, drawing the parallel without meaning to. "Except the storm border was apparently a deliberate design choice, holding the golem continent back until players were ready to find it. This—" she gestured at the roiling, unbroken ring "—doesn't feel deliberate at all. It feels like something that just... happened, and trapped an entire people inside the consequences."

Bram studied the trident still resting in his lap, the connection to Squishy still fresh in his memory. "...If they've been sealed in for this long, completely cut off from the surface world, from trade, from contact with anyone—"

"They've been surviving on whatever they had access to inside the ring," Arista finished, quiet. "However long that's actually been."

Nettle sighed, entirely giving up on the actual timeline making sense, resigned by now to the simple fact that this was apparently just normal, as long as she kept running with this particular crew. She couldn't quite hide the smile tugging at the corner of her mouth regardless.

The crew fell silent for a long moment, the weight of it settling properly now, not just a mystery to solve, not just a quest objective to satisfy, but genuine people, trapped, waiting, on the other side of a wall none of them had ever chosen or deserved.

"...We need to find a way through," Arista said finally, the old, familiar resolve settling into her voice. "Not around it. Not over it. Through it, properly, so whatever comes after doesn't just abandon them the same way this ring already has."

The narrative has been stolen; if detected on Amazon, report the infringement.

Colm, still tracking the ring's full shape against his charts, looked up. "...Do we have any idea how? Cutting through active lava activity isn't exactly comparable to anything we've handled before." He tapped a fresh annotation onto his survey map. "For reference. I've been triangulating the boiling band itself as we've circled it. The active width, outer edge to inner edge, measures just under four meters. Whatever we build has to be long enough to clear that cleanly, with margin on both sides, six meters, say, to be safe."

Arista sat with the problem, feeling the old, restless spark of a genuinely difficult challenge settle in alongside the sober weight of what they'd just discovered.

"...Not yet," she admitted. "But we've built more with less to go on before." She looked out at the shimmering, bubbling ring, feeling something steady and determined settle into her chest. "I think we can figure this one out too."

"...Wait," Bram said, studying the ring properly for the first time since the initial shock of the discovery had settled. "Why are we treating this like we need to cut through solid rock? We're on a steamboat. Boiling water's not exactly a novel threat to a hull that's already survived storms, sea serpents, and Squishy accidentally trying to rip diving bells off the deck."

Arista sat with that, feeling the shape of an obvious oversight settle in. "...You're right. The hull's built to handle considerably worse than boiling water. Nettle's boiler already runs at temperatures that would make this ring look mild by comparison."

Claire checked her readings again, cross-referencing the ring's actual temperature against the ship's known material tolerances. "The bubbling itself isn't structurally dangerous to us specifically. It would be lethal to an unprotected swimmer, certainly, or to a smaller, more fragile vessel. But this hull's reinforced considerably beyond what the ring's actually producing."

"So we could just sail over it," Nettle said, already testing the idea by easing the ship slightly closer to the roiling water's edge, watching the hull's exterior gauges hold steady despite the rising temperature. "Straight through, no special engineering required."

"...We could," Arista said slowly, the realization landing properly now. "The problem was never us getting through. We've got the material tech to handle this without much trouble at all."

Bram considered the ring, then the trident, then the whole shape of the actual challenge finally reorganizing itself in his head. "...So what's the actual problem, then? If we can just sail over it whenever we want."

"The mermaids can't," Arista said quietly, the real shape of the challenge settling in fully now. "That's the entire issue. We have a steel-hulled, adamantium-reinforced ship built specifically to survive extreme conditions. They don't. They're not going to build themselves an equivalent vessel, and even if they somehow did, this is supposed to be a solution that lets them move freely, permanently, not a one-time rescue mission where we ferry them out ourselves."

Claire nodded slowly, following the logic properly now. "...We're not solving 'how do we get in.' We're solving 'how do we give an entire underwater civilization the same freedom of movement they apparently used to have, before this ring ever existed.'"

"Exactly that," Arista said. "This isn't about us reaching them once. It's about making sure they can come and go whenever they want, going forward, without needing outside help every single time."

Bram studied the unbroken, bubbling ring stretching in every direction. "...So we need an actual passage. Something built into the ring itself, permanent, safe for mermaids to use without any of the protection we're relying on."

"Some kind of channel, maybe," Colm offered, already sketching a rough concept. "A controlled gap in the ring's heat, wide enough and cool enough for safe passage, without disrupting the geological activity causing it in the first place."

"That's considerably harder than just sailing over it ourselves," Claire said, already working through the practical challenges. "We're not fighting the ring anymore. We're trying to carve a permanent, livable opening into something actively, continuously producing extreme heat."

Arista sat with the reframed problem, something sharp and eager sparking behind her eyes now that the actual shape of the challenge had finally clarified.

"...Okay," she said, grinning despite the sheer difficulty of what they were apparently about to attempt, boiling water, crushing depth, active heat, and whatever current the churn itself generated, all stacked directly on top of each other. "We're not rescuing anyone. We're not sneaking in and out on a boat they'll never have access to themselves. We're building them a door." She looked out at the shimmering ring, already turning the engineering problem over in her mind. "Let's go figure out how to build a door in a ring of boiling water."
