Jonathan's First Visit to Bright Defile is the decisive threshold event in Jonathan Heights's quest for Sunlight. It transforms the expedition from a hazardous journey through the Lightless World into a spiritual and ontological trial, in which knowledge demands the abandonment of history, possessions, loyalties, and selfhood. Jonathan succeeds where he had previously failed, but his arrival is also an act of irreversible separation: he reaches the green country beyond Bright Defile only after turning nearly every bond to the past into fuel for the crossing.

Causes and Preparation

Jonathan's first approach to Sunlight is defined by the memory of failure. The last time he had reached it, he could go no farther because he lacked both the understanding and the will to proceed. His attention had remained fixed on himself, his place in the world, and what might be gained or lost. The second expedition therefore becomes an exercise in deliberate self-revision rather than merely a geographical return. Jonathan spends the journey clarifying his mind and honing himself toward the single purpose of entering Sunlight, consciously discarding his previous concerns as unworthy of the person he must become.

That preparation is practical as well as inward. At the edge of the map, where no one before him has returned, Jonathan searches his cabin for tools, tricks, references, or records that might help with the final leg and finds nothing useful. The absence is important: he cannot solve the approach to Bright Defile through accumulated equipment or inherited instructions. Even his expedition's material resources have been consumed or exhausted, leaving books and notes among the few remaining possessions. The crossing must therefore be made through a changed relation to knowledge itself, not through another instrument.

The expedition's earlier stages establish the cost of reaching this point. The Endeavor leaves the ruins of Danner's Grasp under a somber mood, passing beyond a settlement reduced to smoldering Zint, lingering fire, and fragments of glowing sheltershrooms. Antomine conducts funerals for the three dead crew members, including George, whose casket is empty because his body cannot be recovered from the corrupted ruins. The bodies are reduced to dust in distilled Luminiferous terrestrite and scattered into the wind; Antomine then performs the same final rites for the dead mercenary boarders. These ceremonies place the approach to Bright Defile within a chain of deaths, losses, and acts of witness rather than presenting the final threshold as an isolated adventure.

The Route Through Thresholds

Jonathan's route toward Bright Defile is marked by machines and rituals that make passage possible while exposing the limits of human control. At Angkor Leng, he uses a remembered sequence of commands three times, causing the gold mechanism to spin, deep machinery to groan, and the ground to shake until the artifice sustaining the doom beneath the city gives way. The release produces a hallucinatory wave that imprints incomprehensible events directly upon reality. Jonathan survives not by understanding the phenomenon analytically, but by recognizing its presence as immediately as light, sound, heat, or cold.

The journey also requires the opening of the Arch of Khokorron. Its machinery withdraws to expose a tunnel several miles in diameter, lined with burning lights and extending beyond sight. The Endeavor is drawn inside by the wind, while the red illumination produces vistas that may not exist and carries a cold, rigid presence unlike any human being. Passage demands a knowledge toll that cannot be paid twice. Jonathan expects to offer the fruit he has kept hidden in his suit, but when he reaches for it, it is gone, leaving the alternative payment of a life. The Arch thus turns knowledge into a material and ethical obligation: understanding is not acquired freely, and a completed passage may require an irreversible sacrifice.

The expedition's religious ceremonies provide a contrasting form of passage. Antomine's service for the dead culminates in the words, "From dust ye were made and dust ye shall be." Later, while confronting the corpse of an ancient dead titan, the same rite places the ship and its crew in a posture of respect before an alien and immense being. Antomine and Jonathan are divided by doctrine and method, yet they briefly stand in agreement over the necessity of honoring and burning the dead. These episodes make Bright Defile the endpoint of a procession through funerals, destruction, and purification, with each threshold requiring the travelers to recognize that survival does not erase what the expedition has consumed.

The Sunlight Trial

At the final approach, Sunlight ceases to be a destination that can simply be reached by distance. Jonathan walks along a narrow path while the light presses upon spirit, self, history, and deed. The trial rises within his mind as a labyrinth made from the very nature of a person, and the experience reveals every individual, place, possession, discovery, and loss that has shaped him. Beacon and his home, Danby's Point, Autochthon Reach, and Danner's Grasp appear as illuminated substances of memory and meaning. Terminus embodies the temptation to settle for what is merely good enough, while the Players and their Game represent the temptation to pursue the wrong dream. Tor Ilek, Angkor Leng, and Ukaresh, with She-Who-Must-Be-Obeyed at its heart, are likewise made present for judgment.

The trial is not limited to Jonathan. Antomine follows behind him with the Lux Guards, but Sunlight exposes the inquisitor's strain. Antomine appears haggard and worn, as though he has crossed a thousand miles rather than a few feet, while progressively less substantial versions of him stream behind him as faith and belief are stripped toward inscrutable truth. The Lux Guards show no comparable suffering because the light reveals them as things rather than people beneath their human trappings. Antomine eventually declares that he and his followers have reached their limit. He opens a device of glass, crystal, and mirrors designed to trap and carry a small portion of Sunlight, attempting to turn revelation into an object that can be transported. Jonathan watches without knowing whether the apparatus works, then continues forward when Antomine orders him to stop.

The final barrier has no statues and no ordinary physical form. It appears as a gulf where the difference between a barrier of understanding and a barrier in the land itself disappears. In a world defined by revelation, the darkness is nevertheless perfectly clear: it is the region of what remains to be surrendered. Jonathan's empty estate burns first. His connections to his chauffeur and housekeeper become additional lights in the gulf. Each decision by which he has erased a route back to his former life contributes to the crossing.

The sacrifice continues through the accumulated history of the expedition. The death of Tiuni and the destruction of Tor Ilek illuminate the path. The books Jonathan threw from the Endeavor become individual stepping-stones. The laying of a god to rest and the burning of its corpse provide another light, while the sacrifice of Angkor Leng appears as a golden city inside a god's dream, radiating briefly before being consumed. Jonathan gives up his friendship with Eleanor McAvey and his banishment from Ukaresh. The image of She-Who-Must-Be-Obeyed appears, stern and commanding, and seems to acknowledge him before joining the pyre. He also rejects the Players and the Game, refusing the dark counterpart of Sunlight's truths.

The last object surrendered is Jonathan's cane. He lays it like a thin sword blade across the final stretch and releases it as the price of crossing the impossible gap. The gesture completes the pattern: a tool associated with his identity and movement becomes a bridge only when he relinquishes it. Jonathan takes the final step through darkness washed by light and enters Bright Defile.

Arrival and Consequences

Beyond the narrow valley lies a vast green country that rises toward proud mountains beneath clouds of purest white. Leaves, grass, stones, and the swift rivers all contain the secrets of time and space, while the sun itself appears older than worlds and older than time. Behind Jonathan, the shrouded lands of the expedition shrink into a dim mote suspended between sunbeams, an overlooked corner of creation. The scale of the view reverses the hierarchy that had governed his journey: the cities, ruins, doctrines, enemies, and possessions that once seemed enormous become almost negligible beside the reality he has entered.

Jonathan's arrival is therefore both triumph and severance. He feels the warmth of the sun, a free wind at his back, and the liberty of truth before him, and he smiles. Yet the smile follows the destruction of the self he previously brought to the threshold. He does not return with an elixir, restore his former relationships, or preserve the expedition's world intact. Bright Defile is reached through a one-way logic of relinquishment, and its revelation confirms that Jonathan's success depends on the loss of the person who once measured every choice by reputation, possession, and personal advantage.

Narrative Significance

As a narrative event, Jonathan's First Visit to Bright Defile completes a separation ritual rather than a conventional homecoming. The expedition departs from communal grief, passes through funerals and the burning of the dead, crosses mechanical and metaphysical gates, and ends with Jonathan abandoning the final object that can accompany him. The sequence repeatedly moves from possession toward dispersal: bodies become dust, cities become sacrifice, knowledge becomes toll, and the cane becomes a bridge before disappearing from his hand.

The event also clarifies the difference between Jonathan's earlier and present selves. His first failure arose from attachment and insufficient will; his second attempt succeeds because he has treated attachment itself as the obstacle. That success is morally and emotionally ambiguous. Bright Defile grants him truth and freedom, but only after the deaths, betrayals, exiles, and renunciations that make the path visible. The final smile is not a return to ordinary life. It is the expression of someone who has crossed beyond the limits that formerly made him recognizable, leaving the dark world behind as a tiny and distant remnant.
