"Don't fight it!" Carter gasped. "Just try to stay calm and keep breathing." His voice was raised over the deep, rhythmic hum that was pounding maddeningly in Lamont's ear, the only sound produced by the spectacle.
Lamont turned his attention away from Captain Carter and realized that the captain was correct - the ground was trembling noticeably beneath their feet. It was a subtle vibration, but persistent, and seemed to be emanating from deep within the moon's icy crust. Lamont's heart pounded as the vibrations traveled up his legs, resonating with a rhythmic throb in his head. He glanced at Carter, who was pressing his free hand against the tower's wall, as if trying to determine the source of the vibrations. Phobos remained silent, his golden eyes scanning the pools of oxygen that were scattered across the terrain. The Martian, with his higher vantage point, had been watching what Lamont was only now beginning to notice: The oxygen appeared agitated. It was beginning to ooze out of the confines of the craters into which it had settled and seep through fissures in the jagged ground.
The ground's pulsing grew stronger, and Lamont felt as if the moon itself were drawing breaths beneath them. He stepped back from the edge of the pool, his movements sluggish as if he were pushing through an invisible barrier. He realized that the only action he could take was to stagger toward Carter where he leaned against the tower wall. It was as if gravity was pulling him not only downward, but inward, toward the tower. The oxygen around their feet began to churn and flow towards the tower like a river of molten glass.
Despite its ponderous appearance, the semi-frozen oxygen was all at once upon them. The molasses-like fluid swirled around their legs, pressing them hard against the rough metallic surface of the structure. Lamont struggled to maintain his footing, but the current was too strong. Beside him, Phobos dug his heels into the ground, barely keeping himself upright. Captain Carter had already lost the battle and was pinned flat against the tower's wall by the viscous flow.
"Don't fight it!" Carter gasped. "Just try to stay calm and keep breathing." His voice was raised over the deep, rhythmic hum that was pounding maddeningly in Lamont's ear, the only sound produced by the spectacle.
Lamont stopped struggling and allowed the tide to drag him backwards. He collided with the tower's exterior and found himself stuck fast, immobilized by the strange suction. The oxygen continued to flow around them, piling into weird gelatin shapes as it gathered around the base of the tower. He clenched his jaw, fighting panic as he struggled to push himself up along the wall, to keep his head above the writhing blue tentacles.
After a time, he found that he no longer had to try so hard. The level of the oxygen was lowering as it seeped into the uneven ground from which the tower emerged. Soon, it was no longer pressing against his chest, and he began to breath more easily. As suddenly as it had begun, the force abated. The three of them all staggered and fell as the unseen hand that had been drawing them toward the tower released its grip, leaving only the downward pull of gravity in its place.
OK, now you are getting weird.
