Unlike a normal area of spacetime, the bubble wasn’t completely impermeable. Some energy leakage occurred from inside to outside (the pressure differential was enormous). Not much, but some, and it was a good thing too, as it helped reduce the thermal buildup while in FTL. Without it, the Valkyrie, and ships in general, wouldn’t be able to stay in superluminal space for more than a few hours.

Kira remembered a description her fourth-year physics teacher had once used: “Going faster than light is like traveling in a straight line along a right angle.” The phrase had stuck with her, and the more she’d learned of the math, the more she’d realized how accurate it was.

She continued to watch her reflection for several more minutes. Then, with a sigh, she darkened the windshield until it was opaque. “Ando: play the complete works of J. S. Bach on a loop, starting with the Brandenburg Concertos. Volume level three.”

As the opening chords sounded, soft and precise, Kira felt herself begin to relax. The structure of Bach had always appealed to her: the cold, clean mathematical beauty of one theme slotting into another, building, exploring, transforming. And when each piece resolved, the resolution was so immensely satisfying. No other composer gave her that feeling.

The music was the one luxury she was allowing herself. It wouldn’t produce much heat, and since she couldn’t read or play games on her implants, she needed something else to keep her from going crazy in the days to come. If she’d still had her concertina, she could have practiced on it, but since she didn’t …

In any case, the soothing nature of the Bach would work with the cabin’s low pressure to help her sleep, which was important. The more she could sleep, the faster the time would go by and the less food she would need.

She lifted her right arm and held it before her face. The suit was even darker than the surrounding darkness: a shadow within shadows, visible more as an absence than an actuality.

It should have a name. She’d been damn lucky to escape the Extenuating Circumstances. By all rights the grasper should have killed her. And if not, then the explosive decompression. The xeno had saved her life multiple times. Of course, without the xeno, she never would have been in danger in the first place.… Still, Kira felt a certain amount of gratitude toward it. Gratitude and confidence, for with it, she was safer than any Marine in their power armor.

After everything they’d gone through, the xeno deserved a name. But what? The organism was a bundle of contradictions; it was armor, but it was also a weapon. It could be hard, or it could be soft. It could flow like water, or it could be as rigid as a metal beam. It was a machine but also somehow alive.

There were too many variables to consider. No one word could encompass them all. Instead, Kira focused on the suit’s most obvious quality: its appearance. The surface of the material had always reminded her of obsidian, although not quite as glassy.
