Joshua checked the neuroiconic displays. “No heat, and precious little radiation. Particle density is up on the norm, but then it’s been fluctuating the whole time we’ve chased round the nebula.” He datavised the flight computer to establish a communication link with Oenone . “How are we doing with the final coordinate?”

“I was pleasingly correct with my earlier estimates,” the voidhawk replied. “I should have the final figure ready for you in another five minutes.”

“Fine.” After their first sighting of Mastrit-PJ, Joshua had checked the figures which Oenone had supplied a couple of times, out of interest rather than distrust. Each time they’d been better than any reading Lady Mac ’s technological sensors could provide. He didn’t bother after that.

“We should be able to measure the photosphere boundary to within a thousand kilometres,” Syrinx datavised. “Defining exactly where it ends and space begins is problematical. Theory has an effervescence zone measuring up to anything between five hundred to half a million kilometres thick.”

“We’ll stick to plan-A, then,” Joshua datavised back.

“I think so. Everything’s checked out as we expected so far. Kempster has activated every sensor we’re carrying, recording it like flek memories are infinite. I expect he’ll let us know if he and Renato spot any anomalies.”

“Okay. In the meantime I’ll plot an initial vector to leave Lady Mac with a neutral relative velocity. I can refine it when you’ve finished working out the coordinate.” He suspected Oenone could supply him with the appropriate vector within milliseconds. But damn it, he had some pride.

Lady Mac ’s star trackers locked on to the new constellations they’d mapped. He brought his navigation programs into primary mode and began feeding in the raw data.

Joshua and Syrinx had decided on an interval of several hours before making the final jump to Mastrit-PJ. Partly it was due to their lack of knowledge on its real position and size. Once that was determined, they intended to emerge in the ecliptic plane, a safe distance above the top of the photosphere, with their velocity matched perfectly to the star’s. It meant the only force acting on them would be the star’s gravity, a tiny tide-like pull inwards. From that vantage point they would be able to scan space for a considerable distance. Logically, the remnants of the Tyrathca’s redoubt civilization should be orbiting the star’s equator. Possibly on a Pluto-type planet that had survived the explosion, or a large Oort-ring asteroid. Although the volume of space was admittedly huge, by jumping in steady increments round Mastrit-PJ’s equator they should eventually be able to find it.

Oenone would also spend the time to completely recharge its energy patterning cells from cosmic radiation, saving its fusion fuel. Not only would that prepare the voidhawk to carry out the search, it would then have the ability to withdraw across a considerable distance, matching Lady Mac ’s sequential jump facility should they unwittingly enter a hostile armed xenoc environment. That was an imaginative worst-case scenario dreamt up by Joshua, Ashly, Monica, Samuel, and (surprisingly) Ruben; which everyone else cheerfully told them verged on outright paranoia. As it turned out, they’d done quite a good job.

A star is a perpetual battleground of primal forces, principally those of heat and gravity which manifest themselves as expansion and contraction. At its core, a main-sequence star is a giant hydrogen fusion reaction, heating the rest of the mass sufficiently to counter gravitational contraction. However, fusion is only as finite as its fuel supply, while gravity is eternal.

After billions of years of steady luminescence, Mastrit-PJ exhausted the hydrogen atoms of its core, burning them into inert helium. Fusion energy production continued within a small shell of hydrogen wrapped around the central region. Temperature, pressure, and density all began to change as the envelope took over from the core as the principal source of heat. As the transformation of its internal structure progressed, so Mastrit-PJ left its original stable luminous sequence behind at an ever increasing rate. Its outer layers began to expand, heated by convection currents surging up from the growing fusion envelope. While on the inside of the envelope, the core continued its gravitational contraction as a snow of helium atoms drifted downwards adding to its mass.

Mastrit-PJ divided into two distinct and very different entities: the centre burning with renewed vigour as it continued its contraction, and the outer layers bloating out and cooling through the spectrum from white through yellow and into red. That was the epoch of stellar evolution from which the Tyrathca had fled. The expanding star inflated out to over four hundred times its original radius, eventually settling down with a diameter of one thousand six hundred and seventy million kilometres. It swept across the three inner planets, including the Tyrathca homeworld, and quickly devoured the two outer gas-giants. There was no exact line to show where the star ended and space began, instead the inflamed hydrogen thinned out into a thick solar wind which blew steadily out into the galaxy. However, for catalogue and navigational purposes, Oenone had defined Mastrit-PJ’s periphery at seven hundred and eighty million kilometres from its invisible core.

Lady Macbeth was the first to emerge, a respectable fifty million kilometres above the wispy radiant sea of dissolving particles. Normal space had ceased to exist, leaving the starship coasting between two parallel universes of light. On one side, the spectral eddies of the nebula jewelled with young stars; on the other, a flat, featureless desert of golden-hot photons.

Oenone emerged twenty kilometres from the dark Adamist ship.

“Contact locked,” Joshua datavised in confirmation to Syrinx as their dish acquired Oenone ’s short-range beacon. Lady Mac ’s full complement of survey sensors were rising out of their fuselage recesses, along with the new systems which Kempster had requested. He could actually see a similar suite deploying from the pods riding in the voidhawk’s lower fuselage cargo cradles.

“I see you,” she replied. “Confirming no rocks or dust clouds in our immediate vicinity. We’re starting the sensor sweep.”

“Us too.”

“How’s your thermal profile?”

“Holding fine,” Sarha replied when he consulted her. “It’s hot out there, but not as bad as the approach to the antimatter station. Our dump panels can radiate it away faster than we’re absorbing it. Wouldn’t want you to fly us too much closer, though. And if you can give us a slow continuing roll manoeuvre, I’d be happy. It’ll avoid any hot-spots building on the fuselage.”

“Do my best,” he told her. “Syrinx, we can cope. How about you?”

“Not a problem at this distance. The foam insulation is intact.”

“Okay.” He fired the starship’s equatorial ion thrusters, initiating the slow barbecue-mode roll Sarha wanted.

The crew were all at their bridge stations, ready to cope with any contingency the red giant threw at them. Samuel and Monica were down in the main lounge in capsule B, sharing it with Alkad, Peter, and Oski, who were accessing the sensor data. Oenone ’s results were being delivered directly to Parker, Kempster, and Renato. Both ships were exchanging their data in real time, allowing the experts to review it simultaneously.

The image of local space built up quickly, charting the strong riot of particles flowing past the hull. Outside didn’t quite qualify as a vacuum.

“Calmer than Jupiter’s environment,” Syrinx commented. “But just as dangerous.”
