Who Was There
Characters present in this moment
A mix of alarm and determination—surface curiosity masking a growing sense of urgency and moral outrage as she grasps the scale of the Menoptra’s oppression and the Animus’s threat.
Barbara, a human companion to the Doctor, endures the Crater of Needles’ toxic atmosphere with visible strain—her eyes sore, her breathing labored. Despite her physical discomfort, she remains intellectually sharp, pressing Hrostar for answers about their forced labor and the true nature of the Carsinome. Her questions are probing yet measured, revealing her role as both an observer and an emerging ally to the Menoptra. She listens intently to Hrostar’s revelations, her expression shifting from curiosity to alarm as the horror of the Animus and the Menoptra’s plight becomes clear.
- • To understand the purpose of the Menoptra’s labor and the true nature of the Carsinome/Animus, so she can assess the danger and potential solutions.
- • To build trust with Hrostar and the Menoptra, positioning herself as an ally in their resistance against the Zarbi and the Animus.
- • The Menoptra’s cause is just, and their suffering under the Zarbi is unjustifiable.
- • The Doctor and her companions may play a crucial role in aiding the Menoptra’s rebellion, given their knowledge and resources.
A weary defiance—surface exhaustion masking a deep, unyielding determination to resist, tempered by the crushing weight of past failures and the looming threat of the Animus.
Hrostar, a wingless Menoptra enslaved in the Crater of Needles, labors alongside Barbara under the watchful eyes of Zarbi sentries. His physical presence is marked by exhaustion—both from the toxic atmosphere and the weight of his permanent wing damage, which he admits renders him flightless forever. He speaks in a measured, weary tone, revealing the harrowing truth about the Carsinome and the Animus while occasionally glancing at the Zarbi to ensure their labor isn’t interrupted. His dialogue is laced with resignation, but flashes of defiance emerge when discussing the Menoptra’s failed rebellion and their untested Isotope weapon.
- • To inform Barbara of the true nature of the Carsinome and the Animus, so she understands the stakes of their labor.
- • To subtly rally her support for the Menoptra’s cause, hinting at the impending arrival of the spearhead and the Isotope weapon as a glimmer of hope.
- • The Menoptra’s rebellion is not yet lost, despite their past failures (faith in the Isotope weapon).
- • The Zarbi are not inherently evil but are controlled by the Animus, making them both victims and oppressors.
A fragile defiance—surface despair masking a deep, collective will to survive and reclaim their homeworld, despite the odds.
The Menoptra, as a collective, are represented through Hrostar’s revelations about their failed rebellion, their enslavement, and their desperate hope in the Isotope weapon. Their presence is felt in the labor taking place in the Crater of Needles—wingless Menoptra toiling under Zarbi supervision, their bodies broken but their spirit not entirely crushed. Hrostar’s mention of Vrestin and the spearhead invokes their broader struggle, painting a picture of a species on the brink of extinction, clinging to a fragile hope for liberation.
- • To liberate the Zarbi from the Animus’s control and reclaim Vortis for the Menoptra.
- • To survive long enough for the spearhead’s arrival and the deployment of the Isotope weapon.
- • The Animus can be defeated, though the cost may be high (faith in the Isotope weapon).
- • The Zarbi are not true enemies but victims of the Animus, making their liberation a moral imperative.
None (as mind-controlled agents, they exhibit no emotional state—only mechanical enforcement of the Animus’s commands). Their presence, however, radiates a chilling, inescapable authority.
The Zarbi manifest as silent, looming sentries in the Crater of Needles, their crystalline weapons glinting under the toxic haze. They harry Hrostar and Barbara with abrupt, wordless commands, ensuring the forced labor of vegetation harvesting continues uninterrupted. Their presence is a constant, oppressive threat—physical manifestations of the Animus’s control. Though they do not speak, their actions (approaching, harrying, enforcing labor) drive the tension of the scene, reminding the characters of their powerlessness.
- • To maintain the forced labor of the Menoptra and Barbara, ensuring the Carsinome’s growth is uninterrupted.
- • To suppress any signs of rebellion or communication, acting as a deterrent to Hrostar and Barbara’s exchange.
- • The Zarbi operate on instinct alone, with no capacity for independent thought or empathy.
- • Their actions are driven solely by the Animus’s directives, making them extensions of its will.
Vrestin is mentioned indirectly by Hrostar as a leader of the Menoptra who participated in the failed liberation attempt and …
Objects Involved
Significant items in this scene
The Carsinome is the physical manifestation of the Animus’s dominion over Vortis—a hive-like structure expanding toward the planet’s core, fed by the Menoptra’s forced labor. In this event, it is the subject of Hrostar’s harrowing explanation, revealed as the destination of the vegetation and acid streams. Its description as a ‘monstrous entity’ that ‘reaches out across Vortis’ elevates it from a mere backdrop to a looming, almost sentient threat. The Carsinome symbolizes the Animus’s insatiable hunger, its growth a metaphor for the planet’s consumption. Barbara’s alarm at learning of its connection to the Animus underscores its role as a narrative villain, driving the urgency of the Menoptra’s plight.
The acid streams in the Crater of Needles are the corrosive veins of the Carsinome, dissolving the harvested vegetation into nutrients that sustain the Animus’s growth. In this event, they function as both a physical barrier (their toxic fumes exacerbate Barbara’s discomfort) and a narrative device—Hrostar’s description of how they ‘draw [the vegetation] to the centre’ through underground streams reveals the Carsinome’s insidious expansion. The streams symbolize the inescapable reach of the Animus, turning the Menoptra’s labor into a self-perpetuating cycle of oppression. Their gurgling, corrosive presence looms over the scene, a constant reminder of the planet’s slow death.
The Isotope weapon, mentioned by Hrostar as the Menoptra’s ‘last hope,’ is an untested but desperate gambit to defeat the Animus. In this event, it serves as a narrative pivot—shifting the conversation from despair to fragile possibility. Hrostar’s admission that it ‘has not been tested’ underscores the Menoptra’s desperation, while Barbara’s reaction (implied in her silence) hints at her role in either aiding or questioning its efficacy. The weapon symbolizes the Menoptra’s defiance, but its unproven nature also introduces tension: Will it work, or will it doom them further? Its mention raises stakes for the companions’ potential involvement in the coming conflict.
The harvested vegetation from Vortis’s surface is the literal fuel for the Carsinome’s expansion, a grim metaphor for the planet’s exploitation under the Animus’s rule. In this event, it serves as both a tool of oppression (forcing the Menoptra and Barbara to labor) and a key to understanding the Carsinome’s growth. Hrostar’s explanation reveals its role in nourishing the underground streams that feed the Animus, making it a tangible symbol of the Menoptra’s enslavement and the planet’s slow consumption. Barbara’s handling of the brittle growths underscores the physical toll of the labor, while Hrostar’s dialogue elevates it to a narrative device—revealing the true horror of what they are sustaining.

Places and their significance in this event
The Carsinome, as described by Hrostar, is the Zarbi’s hive-like stronghold at the hub of the Crater of Needles’ acid streams. Though not physically present in the scene, it looms as the destination of the Menoptra’s labor and the source of their oppression. Hrostar’s revelation that the vegetation is ‘drawn to the centre’ through underground streams paints the Carsinome as a monstrous, expanding entity—both a physical structure and a metaphor for the Animus’s dominion. Its mention elevates the stakes of the scene, as Barbara realizes the true purpose of her forced labor: sustaining the very force that enslaves the Menoptra. The Carsinome’s unseen core (where the Animus resides) adds a layer of dread, symbolizing the unknown horrors awaiting those who dare challenge the status quo.
The Crater of Needles is the oppressive heart of the Menoptra’s enslavement—a vast, jagged pit where wingless Menoptra and Barbara toil under Zarbi supervision, harvesting vegetation to feed the Carsinome. In this event, it functions as a prison, a labor camp, and a crucible for revelation. The toxic atmosphere (corrosive air, blurred vision) mirrors the physical and emotional toll on the characters, while the Zarbi’s patrols and harrying create a sense of inescapable danger. The crater’s needles and acid streams contribute to its claustrophobic mood, reinforcing the Menoptra’s powerlessness. Yet, it is also where Hrostar and Barbara’s exchange takes place, making it a site of reluctant resistance and the transmission of critical information.

Key Dialogue
"BARBARA: Why do they make us heap this vegetation into the acid streams?"
"HROSTAR: It is the raw material for the Carsinome, where the Zarbi live. Fed into these pools, it is drawn to the centre through underground streams, and as we pour it in, the Carsinome grows and reaches out across Vortis."
"BARBARA: Well, what lies at the centre?"
"HROSTAR: None of us have ever seen it and lived, but we call it the Animus."
"HROSTAR: We came here to liberate them. It was disaster. Vrestin, the others, we arrived in advance of the spearhead. Our weapons proved useless. They were taken by the Zarbi who were everywhere. The three of us you met in the cave got away with the communicator, but we could not contact our spearhead."
"BARBARA: And how will you overcome the Animus?"
"HROSTAR: With a new invention of our scientists. It has not been tested but we have placed our faith in the Isop-tope."
