As he unlocked the cage, Sheppard saw the pavilion doors open to the sun. Martinsen stood ha the entrance, staring at the bright air with the toneless expression of a sleepwalker woken from a dark dream. He had shed his feathers, and his body was now dressed in a dozen glimmering images of himself, refractions of past and present seen through the prism of time.

He gestured to Sheppard, trying to warn him away from his wife. Sheppard was certain now that the physician had been given a glimpse into the dream-time, as he mourned Elaine in the hours after her death. He had seen her come alive from the dead, as the images of her past and youth came to her rescue, drawn here by the unseen powers of the Space Centre. He feared the open cage, and the spectre of this winged woman rising from her dreams at the grave’s edge, summoning the legion of her past selves to resurrect her.

Confident that Martinsen would soon understand, Sheppard embraced his wife and lifted her from the bed, eager to let this young woman escape into the sunlight.

Could all this have been waiting for them, around the unseen corners of their past lives? Sheppard stood by the pavilion, looking out at the silent world. An almost tangible amber sea lay over the sandbars of Cape Kennedy and Merrit Island. Hung from the Apollo gantries, a canopy of diamond air stretched across the forest.

There was a glimmer of movement from the river below. A young woman ran along the surface of the water, her silver hair flowing behind her like half-furled wings. Elaine was learning to fly. The light from her outstretched arms glowed on the water and dappled the leaves of the passing trees. She waved to Sheppard, beckoning him to join her, a child who was both his mother and his daughter.

Sheppard walked towards the water. He moved through the flock of orioles suspended above the grass. Each of the stationary birds had become a congested jewel dazzled by its own reflection. He took one of the birds from the air and smoothed its plumage, searching for that same key he had tried to find when he caressed Anne Godwin. He felt the fluttering aviary in his hands, a feathered universe that trembled around a single heart.

The bird shuddered and came to life, like a flower released from its capsules. It sprang from his fingers, a rush of images of itself between the branches. Glad to set it free, Sheppard lifted the orioles down from the air and caressed them one by one. He released the giant butterfly, the quetzal and the iguana, the moths and insects, the frozen, timelocked ferns and palmettos by the water’s edge.

Last of all, he released Martinsen. He embraced the helpless doctor, searching for the strong sinews of the young student and the wise bones of the elderly physician. In a sudden moment of recognition, Martinsen found himself, his youth and his age merged in the open geometries of his face, this happy rendezvous of his past and future selves. He stepped back from Sheppard, hands raised in a generous salute, then ran across the grass towards the river, eager to see Elaine.

Content now, Sheppard set off to join them. Soon the forest would be alive again, and they could return to Cocoa Beach, to that motel where Anne Godwin lay in the darkened bedroom. From there they would move on, to the towns and cities of the south, to the sleepwalking children in the parks, to the dreaming mothers and fathers embalmed in their homes, waiting to be woken from the present into the infinite realm of their time-filled selves.

Report on an Unidentified Space Station

By good luck we have been able to make an emergency landing on this uninhabited space station. There have been no casualties. We all count ourselves fortunate to have found safe haven at a moment when the expedition was clearly set on disaster.

The station carries no identification markings and is too small to appear on our charts. Although of elderly construction it is soundly designed and in good working order, and seems to have been used in recent times as a transit depot for travellers resting at mid-point in their journeys. Its interior consists of a series of open passenger concourses, with comfortably equipped lounges and waiting rooms. As yet we have not been able to locate the bridge or control centre. We assume that the station was one of many satellite drogues surrounding a larger command unit, and was abandoned when a decline in traffic left it surplus to the needs of the parent transit system.

A curious feature of the station is its powerful gravitational field, far stronger than would be suggested by its small mass. However, this probably represents a faulty reading by our instruments. We hope shortly to complete our repairs and are grateful to have found shelter on this relic of the now forgotten migrations of the past.

Estimated diameter of the station: 500 metres.

Our repairs are taking longer than we first estimated. Certain pieces of equipment will have to be entirely rebuilt, and to shorten this task we are carrying out a search of our temporary home.

To our surprise we find that the station is far larger than we guessed. A thin local atmosphere surrounds the station, composed of interstellar dust attracted by its unusually high gravity. This fine vapour obscured the substantial bulk of the station and led us to assume that it was no more than a few hundred metres in diameter.

We began by setting out across the central passenger concourse that separates the two hemispheres of the station. This wide deck is furnished with thousands of tables and chairs. But on reaching the high partition doors 200 metres away we discovered that the restaurant deck is only a modest annexe to a far larger concourse. An immense roof three storeys high extends across an open expanse of lounges and promenades.

We explored several of the imposing staircases, each equipped with a substantial mezzanine, and found that they lead to identical concourses above and below.

The space station has clearly been used as a vast transit facility, comfortably accommodating many thousands of passengers. There are no crew quarters or crowd control posts. The absence of even a single cabin indicates that this army of passengers spent only a brief time here before being moved on, and must have been remarkably self-disciplined or under powerful restraint.

Estimated diameter: 1 mile.

A period of growing confusion. Two of our number set out 48 hours ago to explore the lower decks of the station, and have so far failed to return. We have carried out an extensive search and fear that a tragic accident has taken place. None of the hundreds of elevators is in working order, but our companions may have entered an unanchored cabin and fallen to their deaths. We managed to force open one of the heavy doors and gazed with awe down the immense shaft. Many of the elevators within the station could comfortably carry a thousand passengers. We hurled several pieces of furniture down the shaft, hoping to time the interval before their impact, but not a sound returned to us. Our voices echoed away into a bottomless pit.

Perhaps our companions are marooned far from us on the lower levels? Given the likely size of the station, the hope remains that a maintenance staff occupies the crew quarters on some remote upper deck, unaware of our presence here.

Estimated diameter: 10 miles.

Once again our estimate of the station’s size has been substantially revised. The station clearly has the dimensions of a large asteroid or even a small planet. Our instruments indicate that there are thousands of decks, each extending for miles across an undifferentiated terrain of passenger concourses, lounges and restaurant terraces. As before there is no sign of any crew or supervisory staff. Yet somehow a vast passenger complement was moved through this planetary waiting room.
