Barbara discovers hidden refuge from Zarbi

Hrostar’s urgent warning of approaching Zarbi forces Barbara and the group into a desperate retreat across the plateau. As they flee, Barbara stumbles into a concealed rock crevice—an unnoticed sanctuary—triggering its hidden door mechanism. The Zarbi and their parasitic grubs cannot follow, granting the companions a temporary reprieve. This discovery transforms their passive evasion into a tactical advantage, offering a strategic pivot against the Animus’ control over the Zarbi. The moment underscores Barbara’s resourcefulness and the planet’s hidden defenses, while also setting up the group’s next move: exploiting the Animus’ blind spot in this sanctuary to regroup and counterattack. The event’s tension hinges on the contrast between the Zarbi’s relentless pursuit and the sudden, almost serendipitous safety of the crevice, reinforcing the theme of unexpected resilience in the face of oppression.

Who Was There

Characters present in this moment

4

Tense and focused, with a surge of adrenaline-fueled clarity—she is fully engaged in the moment, her survival instincts sharpened by the immediate threat.

Barbara is the linchpin of this moment, her actions driven by a mix of instinct and desperation. She backs away from an oncoming Zarbi, her retreat accidental but fortuitous as she stumbles into the concealed rock crevice. Her physical collision with the door mechanism is the catalyst that saves the group, turning a moment of vulnerability into an opportunity. She moves with the resourcefulness of someone who has learned to adapt quickly in hostile environments, her dialogue—'We're surrounded. Come on!'—reflecting both her awareness of the danger and her determination to keep the group moving.

Goals in this moment
  • Avoid capture or harm from the Zarbi at all costs
  • Find a way to turn the tide of the pursuit, even if temporarily
Active beliefs
  • The Zarbi’s control of the plateau is absolute, but hidden weaknesses can be exploited
  • Every stumble or misstep could be the key to survival in this environment
Character traits
Resourceful under pressure Quick-thinking and adaptive Determined and unyielding Physically reactive (stumbling triggers the door)
Follow Barbara Wright's journey
Hrostar
primary

Highly focused with an undercurrent of controlled anxiety—his priority is survival, and he channels that into action rather than panic.

Hrostar is the first to spot the approaching Zarbi, his voice sharp with urgency as he shouts the warning that sets the group into motion. He moves with the practiced caution of a seasoned rebel, his body tense and alert as he scans the plateau for any advantage. His leadership is implicit in his actions—he doesn’t hesitate to urge Barbara forward, his pragmatism driving the group toward the only viable escape route: the concealed crevice. His role here is that of the tactical guide, ensuring survival through quick thinking and decisive action.

Goals in this moment
  • Ensure the group’s immediate escape from the Zarbi
  • Find a temporary refuge to regroup and strategize
Active beliefs
  • The Zarbi’s pursuit is relentless and must be evaded at all costs
  • Hidden refuges like the crevice are critical to outmaneuvering the Animus’ forces
Character traits
Urgent and alert Pragmatic and decisive Protective of the group Tactically observant
Follow Hrostar's journey
Zarbi
primary

None (as extensions of the Animus’ will, they operate without individual emotion, but their actions radiate oppressive intent).

The Zarbi are the relentless antagonists of this scene, their skittering advance a constant threat that forces the group into retreat. They close in on Barbara and Hrostar with single-minded aggression, their crystalline weapons and sheer numbers making escape seem impossible. Their inability to follow the group into the concealed crevice is a rare moment of vulnerability, highlighting the limitations of their hive-mind control. The Zarbi’s presence here is purely antagonistic, their actions driven by the Animus’ compulsion to crush resistance and maintain dominance over Vortis.

Goals in this moment
  • Capture or eliminate Barbara and Hrostar to prevent further resistance
  • Maintain control over the plateau and suppress any hidden refuges
Active beliefs
  • The Animus’ control is absolute, and resistance is futile
  • Any deviation from the pursuit protocol is a failure of the hive mind
Character traits
Relentless and aggressive Single-minded in pursuit Physically imposing and threatening Vulnerable to environmental or structural advantages (e.g., the crevice)
Follow Zarbi's journey
Supporting 1
Zarbi Grub
secondary

None (as extensions of the Animus’ will, they operate without individual emotion, but their actions contribute to the oppressive tone).

The Zarbi grubs accompany their larger counterparts in the pursuit, their smaller size and parasitic nature making them extensions of the Zarbi’s hive-mind aggression. They scuttle alongside the Zarbi, their presence reinforcing the sheer numbers of the Animus’ forces. Like the Zarbi, they are unable to follow the group into the crevice, their failure to breach the sanctuary underscoring the group’s temporary reprieve. Their role is purely supplementary, adding to the oppressive atmosphere of the chase.

Goals in this moment
  • Support the Zarbi in capturing or eliminating the group
  • Extend the Animus’ reach through collective enforcement
Active beliefs
  • The Animus’ will must be obeyed without question
  • Resistance is to be crushed through overwhelming numbers
Character traits
Parasitic and hive-minded Aggressive in pursuit but physically limited Dependent on Zarbi leadership Symbolic of the Animus’ pervasive control
Follow Zarbi Grub's journey

Concealed Rock Crevice (Plateau Sanctuary Entrance)

The concealed rock crevice is the pivotal object in this event, serving as both a hidden refuge and a tactical advantage. Initially overlooked amid the chaos of the retreat, it is triggered by Barbara’s accidental collision, revealing a sanctuary that the Zarbi and their grubs cannot breach. The crevice’s narrow fissure and seamless integration into the rock face make it an ideal hiding place, turning a moment of desperation into a strategic pivot. Its discovery underscores the theme of unexpected resilience, as the planet itself seems to offer a fleeting advantage against the Animus’ oppressive control.

Sanctuary Door Mechanism (Plateau Crevice Trigger)

The hidden door mechanism is the functional heart of this event, transforming a seemingly ordinary rock face into a lifesaving refuge. Triggered by Barbara’s stumble, it slides open with precision, revealing the crevice’s interior before sealing shut behind the group. This mechanism is a testament to the Menoptra’s or Vortis’ ancient defenses, designed to protect against threats like the Zarbi. Its seamless operation—opening just in time and closing to block pursuit—highlights the narrative’s reliance on serendipity and hidden advantages in the face of overwhelming odds.

Concealed Rock Crevice

The concealed rock crevice is the sanctuary of this event, a narrow fissure carved into the plateau that becomes the group’s refuge. Its sudden appearance—triggered by Barbara’s stumble—transforms the group’s desperate flight into a moment of relative safety. The crevice’s cool, shadowy interior contrasts sharply with the exposed plateau, offering a respite from the Zarbi’s relentless pursuit. Its role is both practical (a place to regroup) and symbolic (a hidden defense against the Animus’ control), reinforcing the theme of resilience in the face of oppression.

Sayo Plateau

The Sayo Plateau is the battleground of this event, its vast, barren expanse a stage for the group’s desperate retreat. The open terrain, swirling dust, and jagged rock face create a sense of exposure and vulnerability, amplifying the tension as the Zarbi close in. The plateau’s lack of cover makes the discovery of the concealed crevice all the more critical, turning a landscape of oppression into a momentary haven. Its role here is dual: a site of relentless pursuit and, paradoxically, a place where hidden refuges can be found.
