Kirk was almost as startled as the unlucky warrior. He spun around to see who had saved him.
A statuesque female figure emerged from the fiery oasis striding confidently toward them. The idol was cradled securely in the crook of her arm,while her other hand gripped a phaser pistol of unfamiliar design. Smoke and shadows partially concealed her identity.
Kirk blinked in confusion. “Bergstrom?”
For a moment Kirk thought that the murdered crew member had somehow come back to life, but then the woman stepped into a patch of moonlight and Kirk saw that she was a stranger. A skintight blue uniform flattered her attractive figure, which would have warranted closer attention under different circumstances. She appeared human, or humanoid, with alert blue eyes and upswept blond hair combed neatly atop her head. A badge in the shape of a stylized Starfleet emblem was affixed to her chest. Her striking features were adorned with metallic implants or ornaments that seemed to be embedded surgically in her flesh. One such implant partially framed her left eye, while another resembled a cybernetic spider lodged under her right ear. She regarded Kirk with a cool, quizzical expression.
“James Tiberius Kirk,” she greeted him. “Captain of the U.S.S. Enterprise. Designation: NCC-One-Seven-Zero-One?”
“That’s right,” he said, puzzled. “Who…?”
“You’re welcome.”
