The Sap Cascade

Rylanor, Imperial Mining Complex, Rivenholt.

Foreman Harker pressed his thumb over a fresh scuff on his battered wrist monitor, frowning at the display. The underground air tasted of iron and old oil; a familiar blend after decades in the mines. Around him, the usual hum of drills and shouted orders filled the shaft—routine, comforting.

“Pressures jumped again,” called Jorus, squinting at his own readout. “I don’t get it. None of this matches the profiles for this seam.”

“Just keep an eye on it,” Harker replied, voice even. “We’ll run a manual check if it keeps up.” He glanced up through the gridwork of metal and shadow, feeling a subtle, out-of-step tremor through his boots. Odd, but the mountain always found new ways to complain.

The routine was shattered by a sharp, rising whine—a sound that sliced through the din. Benches rattled, dust drifted down. The drill’s steady rumble grew erratic, strained, until it groaned—a sound like metal biting into something far tougher than rock.

“Shut it down, now!” Harker shouted, the urgency in his voice echoing through the shaft.

Too late. A low hum built to a crescendo before a blinding burst of blue-white light erupted beneath the drill, flooding the shaft with a cold, unnatural glow. The machinery stuttered, metal protesting violently as if caught in a fierce struggle

Harker’s eyes widened, watering at the brightness. Blinking against the glare, he beheld an impossible sight: a jagged tear in the stone pulsing with raw energy, as if reality itself were being peeled away. Through it, glimpses of mist and strange light danced, revealing the silhouette of distant mountain peaks that didn’t belong to Rylanor’s underworld. A portal—a window to another world.

A gasp broke the tension. Chen, always the first to check on problems, had edged too close. Blue energy arced up his arm; his body stiffened, face twisting in alarm.

“Something… it’s moving—inside,” he managed, voice distant and bewildered.

“Stay back!” Harker ordered, waving the others out of reach. Hitting the abort, emergency klaxons blared as the machinery wound down in a frantic protest.

As the miners withdrew, Harker lingered, staring into the shifting tear. He toggled his comm, voice steady but laced with urgency. “Control, this is Harker. We’ve encountered something unprecedented. Energy readings are off the scale. Requesting containment and specialist teams immediately.”

A pause on the line, then a clipped reply: “What is the current status of the shaft?”

Swallowing hard, watching the light pulse and twist, he replied, “The breach is active but stable—holding at about three by two meters. There’s a landscape on the other side.”

Three hours later, the shaft was ringed in temporary barricades and harsh white lights. Captain Elara Voss double-checked the seals on her armour while reviewing the latest probe data: breathable atmosphere, gravity nearly standard, terrain stable. The drones had relayed glimpses of dense forest and what looked like thick fog at ground level, but the visuals had been clouded by portal interference. One frame showed the blurred outline of a colossal object looming in the sky—likely a planetary body, but details were inconclusive. No hazards detected. The team was cleared to proceed.

“Final checks,” she called. Her team moved with efficient caution, voices steady, eyes on their instruments.

Voss braced herself and stepped on to the portal in the shaft floor. For a split second, gravity seemed to vanish—a fleeting, weightless sensation, not unlike a teleport jump—then her boots struck spongy, unfamiliar ground. She staggered, momentarily disoriented, until her senses caught up. Some of the team weren’t so lucky: one doubled over, retching; others looked green around the gills, blinking hard as they tried to steady themselves.

The air was crisp, carrying the faint tang of resin and electricity. At ground level, a low-lying mist clung to the earth, swirling around their boots but thinning quickly just a short distance away. Above, the sky opened—the view far clearer than the probe’s limited feed had suggested.

Instinct made her look up.

There, low on the horizon, the sky was dominated by another world. Not a perfect sphere, but stretched and distorted—teardrop-shaped, as if drawn towards the planet by an immense, unseen force. Its pointed end angled earthward, clouds and storms swirling around the tip. In the new light, gold and blue shadows traced its curves, and between the two planets, faint shimmering bands arced across the sky—like a celestial bridge.

Even the land beneath her seemed subtly altered. The horizon appeared to rise ever so slightly in the direction of the great planet, the ground and sky alike pulled toward their cosmic twin.

For a split second, Voss’s mind reeled: Is it falling toward us? Are we in danger? The sight was so overwhelming that, for a heartbeat, she forgot to breathe. Behind her, the team’s Xenobiologist Taylan breathed, “Sap…” The words were almost a whisper, half awe, half disbelief.

Voss let her gaze linger, taking in the impossible scene. The gravity beneath her boots felt unchanged, but the sheer proximity of other planet seemed to draw her upward, as if the land and the heavens were being gently tugged together by invisible tides.

No one spoke. Protocols, sensor checks, even the mission briefly forgotten—all felt small in the presence of that sight. She sensed her team behind her, motionless, their silence deeper than any order. For that long moment, the only reality was the weight of a second world—a reminder of how small, how unprepared, they truly were.

“Proceed with caution everyone, stay in pairs” she said at last, her voice tight and hushed. Even then, she could not look away.

She knelt, brushing her gloved hand over the unfamiliar undergrowth. The plants recoiled, then stilled. She wasn’t sure if she’d imagined it—a subtle response, or just nerves. The team fanned out, moving with reverent caution, as if afraid to break the spell.

The light felt different here; sounds seemed muted, the air heavy with anticipation. Voss felt—for the first time in years—a stirring of something like fear, or wonder, or both. For a moment, she almost believed the world itself was watching.

She keyed her comm, choosing her words carefully. “Atmosphere is stable. We are detecting dense, heavy mineral deposits on the scans. The terrain is… like nothing we’ve catalogued. Visibility is good. The local flora seems sensitive to movement—possibly reactive, but not hostile. We’re proceeding with caution.” She hesitated, searching for words. “There’s more here than we expected. It feels…” She stopped. The rest could wait for the debrief. They were professionals, but no training could have prepared them for this.

In the command centre, holographic projections spun above the table—energy readouts, shifting topography, and a looping feed from the orbital probe. General Tiberius Ardent studied the data, his expression inscrutable. The probe’s live transmission, now stabilized, displayed a breathtaking vista: two planetary bodies locked together, each stretched into a teardrop by their mutual gravity, the pointed ends straining toward one another. The probe’s position made it clear—the pointed tips of two planet sized objects hovered several thousand miles apart, their outer atmospheres mingling in a swirling, luminous bridge. The vast arc of clouds and energy between the worlds shimmered like dawn caught mid-motion.

Captain Voss’s latest field report played in the background, relaying atmosphere readings and the explorers’ first, stunned silence beneath the twin planet’s looming presence.

Science Director Merin, hunched over a tablet, mused, “The gravitational distortion is extreme, and the sap measurements are extraordinary. Both bodies—nearly equal mass—are so close, their surfaces are almost within reach. The bridge is more than just clouds; there could be material transfer.”

Sera, the Emperor’s liaison, added, “The Cartography guys want designations for the logs. The Astrological team suggests ‘Calestra’ for the slightly larger world, and ‘Zylara’ for the surface world reached by the portal.”

General Ardent nodded. “Calestra and Zylara—a binary pair. Initial findings show rich deposits of high-density ores, high sap levels, and an atmospheric bridge. Record the minimum separation.” He glanced down at the readout. “They are about 4,750 miles apart at their closest points, with their outer atmospheres blending together in a swirling, luminous bridge.” Sera entered the names into the record. “Calestra for the companion, Zylara for the world our team is on. Both flagged as provisional until Imperial ratification.”

“Send the update to all teams,” General Ardent said. “And alert the administration and press office. If we don’t assign names, someone else will.”

He watched as the projection rotated: two teardrop planets, nearly touching, bound in a dance that defied the ordinary.
