Chapter 27 begins with an unexpected turn of events on Niflheim, marking a year since the colonists arrived. The arrival of spring surprises the settlers, as rising temperatures cause the snow to melt, revealing the earth beneath, which is quickly covered by lichen. This rapid transformation hints at the possibility of agricultural development in an area where such growth was previously thought to be unfeasible. The mission planners, who had anticipated a stable climate due to Niflheim’s nearly circular orbit and minor axial tilt, are thrown off balance by this shift. After investigating, it is revealed that they had neglected to account for a known but previously unconsidered factor: the sun’s marginally variable output. This subtle yet crucial change in the sun’s energy output results in unexpected environmental conditions, creating a complicated challenge for the colony. While the early signs point to potential agricultural success, there is an underlying uncertainty about how this climatic shift could impact the long-term stability of the colony’s environment.

Initially, the colonists are optimistic about the spring change, but their excitement is tempered with caution. Although the climate stabilizes into a comfortable range, allowing the settlers to explore agricultural possibilities beyond the safety of the dome, concerns begin to mount over the unpredictability of the changing weather. Mickey and Nasha take advantage of the new conditions and decide to venture outside, even though the colony still relies on rebreathers due to the low oxygen levels in the atmosphere. Their excursion triggers a wave of nostalgia for Mickey, who reflects on the arid deserts of Midgard, drawing a comparison between the rare precipitation there and the emerging biosphere on Niflheim. Just as life on Midgard thrives under sporadic rainfall, Niflheim is showing signs of new plant and animal life that may soon become the foundation for the colony’s agricultural goals. While this potential is encouraging, there is still much to be understood about the planet’s ecosystem and the sustainability of such growth, especially in light of the previously overlooked climatic changes. The contrasting realities of hope and caution continue to shape the colony’s efforts to adapt to their new environment.

As Mickey and Nasha move further from the dome, Mickey reveals a hidden agenda: he intends to check on something important near an area overtaken by creepers. This unexpected revelation adds tension to their journey, as the nature of Mickey’s actions becomes unclear. Their trek leads them to an underground tunnel, where Mickey retrieves a concealed bomb that had been buried, hidden in plain sight. Nasha’s surprise turns to concern as she questions why Mickey kept the bomb secret from their superiors, particularly Marshall, who would have seen it as a serious threat. Mickey explains that he chose to leave the bomb where it was, hidden near the creeper-infested area, to act as a safeguard for the colony. His reasoning was that the bomb might one day be needed to protect the settlement from potential threats, though his decision to hide it raises questions about his trust in the chain of command. The secrecy surrounding the bomb reveals a deeper level of tension and mistrust within the colony’s leadership, adding complexity to the dynamics between Mickey, Nasha, and the other members of the mission.

With the bomb secured once more, Mickey and Nasha are left to ponder the implications of what they have uncovered. Although no immediate plan exists for dealing with the potential danger the bomb represents, its existence hangs heavily over the pair. The uncertainty surrounding the situation—especially given the possibility that Marshall might still be alive—creates a feeling of unease. Nasha expresses her worries about the precarious position they are in, given that no contingency plans are in place should the bomb be discovered or misused. Mickey remains silent on the issue, unable to provide clear answers to the uncertainties that loom ahead. They make the difficult decision to return to the dome, leaving behind the explosive secret that continues to hover over them. The bomb’s discovery and the way it is handled underscore the high stakes involved in their mission on Niflheim, where the potential for danger is as tangible as the promise of new life. The chapter concludes with the unresolved tension surrounding the bomb, leaving both Mickey and Nasha grappling with the weight of their discovery and what it could mean for their future on the planet. Their return to the dome signals a return to the relative safety of the colony, yet it also highlights the unresolved risks that continue to define their existence.
