Diving forward, Thorne met Sterling's charge with a savage shoulder block. The impact rocked both men, a guttural grunt torn from Thorne's throat as he absorbed the force. Sterling, propelled by fury, twisted, a fist connecting with Thorne's jaw. Stars exploded behind Thorne's eyes. Pain lanced through him. He shook his head, clearing the haze. Not an option to falter now. Concrete dust rained down. Groaning sounds echoed from the very foundations of the observatory. Above them, a massive crack spider-webbed across the reinforced glass dome, admitting a sliver of grey, panicked sky. Sterling snarled, his face a mask of thwarted rage. He swung again, a wild, powerful punch aimed at Thorne's temple. Ducking low, Thorne drove his own fist into Sterling's gut. The wind left Sterling in a choked gasp. Staggering back, Sterling coughed, then lunged with renewed ferocity. He was a cornered animal, all instinct and desperation. Thorne parried a vicious knee aimed at his groin, then countered with a rapid flurry of strikes. His knuckles connected with Sterling's ribs, a dull thud resonating in the crumbling chamber. Sterling grunted, but his eyes remained fixated on Lena, a chilling, murderous intent burning within them. Protecting Lena was Thorne's only thought. He moved with a brutal efficiency, a primal dance of defense and attack. Every blow he landed was for her, every block a shield against Sterling's intent. Lena’s fingers flew across The Nightingale's strings, a desperate counter-frequency humming against the destructive vibrations. She could feel the building groaning around her, the instrument vibrating with an alarming intensity. Her focus was absolute, yet a part of her screamed for Thorne, for the brutal fight unfolding just meters away. Another tremor shook the platform. A section of the ceiling, heavy with equipment, detached and crashed near them. The air filled with more dust and the stench of ozone. Thorne used the distraction, sweeping Sterling’s legs out from under him. Sterling went down hard, hitting the metal floor with a clang. He wasn't out. Scrambling, Sterling reached for a discarded pipe, his eyes glinting with manic purpose. Thorne kicked it away before Sterling could grasp it, then stomped on Sterling's wrist, pinning him. Sterling roared, a sound of pure frustration. He thrashed, trying to dislodge Thorne, his free hand clawing at Thorne’s leg. Thorne ignored the pain, his grip unwavering. He knew this had to end, now. Leveraging his weight, Thorne brought his knee down hard, aiming for Sterling’s shoulder. A sickening pop echoed. Sterling screamed, a raw, animal sound that cut through the cacophony of destruction. His struggles weakened. Thorne pressed his advantage, pinning Sterling's other arm, effectively immobilizing him. Sterling was gasping, his face contorted in agony and defeat. His gaze, however, still held a flicker of defiance, a twisted triumph.
