Feral on the Ice
The math for the warp jump was a nightmare of General Relativity:
$$ds^2 = -c^2 dt^2 + [dx - v_s(t) f(r_s) dt]^2 + dy^2 + dz^2$$
"The velocity ($v_s$) is theoretically infinite," Rhys said, looking at Elara. "But the stress on the 'Biomass' inside—the million people—will be catastrophic if the bubble isn't perfectly stabilized. We need a Septet."
"We're only six," Kael pointed out, his violet veins pulsing. "Even with Julian, we’re short a pillar."
"No," Elara said, her eyes tracing the silver light in the sky. "The seventh isn't a person. It's the Memory of the Stack."
