The San Jacinto Mountains are both refuge and point of departure in the post-catastrophe narrative: they shelter the First Colony, whose survival depends on an aging electrical system, and frame the route by which an expedition leaves for Colorado. The mountains’ apparent security is conditional. Their turbines can keep turning, but deteriorating batteries, restricted communication, and the demands of travel expose how much the community depends on fragile infrastructure.

Setting and the First Colony

The narrative identifies the First Colony as being in the San Jacinto Mountains, within the California Republic, in 92 A.V. This location establishes a contrast between the protected settlement and the wider landscape through which its inhabitants must eventually travel. The mountain is not merely a backdrop: it holds the community’s power and communications systems, while the routes down from it connect the Colony to places where its people must seek answers and resources.

The mountain’s remoteness has a history shaped by decisions about population and contact. According to Michael’s account, the radio had once led Walkers to the Colony, an outcome the Builders had not anticipated. The community later prohibited radio use, removed the antenna, and scattered its parts. Although that restriction may once have conserved food, fuel, and space under the lights, it left the Colony less able to reach beyond the mountain just as its electrical supply became precarious.

Infrastructure and vulnerability

The Colony’s wind turbines offer a visible source of power, but the system depends on batteries that cannot simply be repaired. Michael watches their decline on an old CRT monitor: the cells have lasted far longer than intended, yet their membranes are failing, and his estimate is that the lights may last only another year or two. The turbines can generate electricity in the wind, but without batteries to store and regulate it, a windless night could bring the system down. The mountain community’s apparent independence therefore rests on technology whose replacement is unavailable.

A later unexplained outage makes that dependence immediate. Michael finds the lights off, hurries back to the Lighthouse, and discovers that the main breaker is open; closing it restores power. He reports a possible surge, though the system log offers no confirmation and his checks uncover no fault. The episode does not resolve why the breaker opened, but it underscores how quickly a single interruption can provoke alarm in a settlement already facing the prospect of long-term power failure.

Routes down the mountain

The mountain’s geography shapes the expedition’s movement. On the descent toward the power station, the party travels with the turbine array spread across the flats of the San Gorgonio Pass below. Hot, dry wind makes conversation impossible, and the road ends at Banning, from which the group plans to continue inland along the Eastern Road. The route turns the energy landscape into a practical landmark: the turbines are both part of the Colony’s infrastructure and a feature the travelers pass as they leave its familiar terrain.

The descent is not simply a matter of following a road. When Alicia decides that the group must reach the guns before their pursuers, she leads them down the mountain. Later, Peter and the others approach the power station from behind after finding that their first route is too steep and obstructed. At the compound, the absence of movement is not reassuring: Alicia recognizes that the fence has no power. The journey therefore carries the Colony’s vulnerability with it, linking the failing systems above to the dangers encountered below.

Departure and narrative significance

The San Jacinto Mountains are also the expedition’s point of origin for a much longer passage. In her journal, Sara Fisher identifies herself as one of eight people traveling from the mountains to Telluride, Colorado, and records that the group has reached an army bunker north of Twentynine Palms. The mountains are thus the start of a journey whose purpose is not only geographic: the travelers carry a record of events and the expectation that someone in the future may want to know what happened.

As a setting, the mountains hold together refuge, isolation, and departure. The First Colony’s lights make settlement possible, but the batteries are decaying; communication has been deliberately dismantled; and the expedition must descend through exposed terrain toward contested or unpowered sites. The place’s significance lies in that tension: it protects a community for a time, yet its infrastructure and its boundaries cannot make it self-sufficient forever.
