# Scene 1 – The Hive Awakens ### Boxed Read Aloud > The passage beyond the prison chamber narrows into a winding tunnel formed entirely from living flesh. Thick veins pulse beneath translucent membranes, carrying pale blue fluid through the walls and ceiling. Every few moments, the floor shifts almost imperceptibly beneath your feet, as though some immense heartbeat echoes through the structure. > > Suddenly, the whispers inside your minds become louder. They overlap one another in a chaotic chorus before settling into a single, focused command. > > _"Prisoners have escaped. Seal all transfer routes. Search every chamber."_ > > Throughout the hive, fleshy membranes contract shut across distant passages. Heavy footfalls echo somewhere ahead, while elsewhere hurried movement suggests the colony has begun responding to the disturbance. --- ## What the Players Notice - The colony is now on alert. - Patrols are increasing. - Certain passages periodically seal themselves. - Psychic communication flows constantly through the hive. - The Elder Brain appears capable of coordinating every creature simultaneously. --- ## Investigation |Check|DC|Information| |---|---|---| |Arcana|14|The psychic communication originates from a single immensely powerful source.| |Nature|15|The walls are alive and respond to the colony's commands.| |Perception|13|Patrols follow predictable routes.| |Survival|14|Airflow suggests several major chambers lie deeper within the hive.| --- # Scene 2 – Crossing the Central Artery The characters reach an enormous corridor that serves as the colony's primary thoroughfare. Unlike the prison tunnels, this chamber is busy. Mind flayers rarely travel here themselves. Instead, the corridor is occupied by thralls transporting supplies, grimlocks escorting prisoners, and intellect devourers moving independently between chambers. The players must cross without exposing themselves. --- ## Read Aloud > The narrow passage opens onto a vast organic corridor stretching far beyond the limits of your vision. Massive rib-like supports arch overhead, while thick veins pulse beneath the translucent floor. Every few moments, fleshy platforms emerge from the walls carrying grimlock guards, frightened prisoners, or grotesque biological cargo before disappearing once more into the hive. > > The chamber is alive with movement. Unlike the prison, there is no obvious moment when the passage is empty. --- ## Encounter Objective Cross the artery without raising the colony's alert level. --- ## Running the Encounter Rather than a single Stealth check, treat this as a skill challenge requiring **5 successes before 3 failures**. Suggested skills include: - Stealth (DC 14) to move unseen between cover. - Perception (DC 13) to identify safe moments to advance. - Investigation (DC 14) to understand the movement patterns of the living platforms. - Acrobatics (DC 14) to cross exposed sections quickly. - Athletics (DC 15) to climb along overhead tendrils. - Deception (DC 16) if disguised as thralls or using illusions. - Survival (DC 14) to identify quieter maintenance passages. Encourage creative use of spells and class abilities. A successful use of appropriate magic, such as _Pass without Trace_, _Minor Illusion_, or _Misty Step_, may grant an automatic success if employed thoughtfully. --- ## Success The party crosses unseen and gains valuable knowledge of the colony's layout. Each character gains advantage on their first Stealth check in the next scene as they become more familiar with the hive's rhythms. --- ## Failure The party reaches the opposite side but attracts unwanted attention. A patrol begins searching nearby passages, increasing the difficulty of future Stealth checks by 2 until they evade pursuit. No combat begins unless the players choose to engage. --- # Scene 3 – The Memory Pools The tunnel widens into a chamber containing several shallow pools filled with shimmering, silver liquid. Organic tendrils descend from the ceiling into each pool, carrying faint pulses of psychic energy. These pools are used by the colony to store and exchange memories collected from captives. --- ## Read Aloud > The chamber is silent except for the slow drip of silver fluid into a series of circular pools. The liquid reflects no light, yet images ripple across its surface—faces, cities, battles, forests, and unfamiliar stars. Every few moments the memories dissolve before new visions replace them. > > Thin strands descend from the ceiling into each pool, twitching gently as though carrying thoughts from one part of the hive to another. --- ## Investigation A character who examines a pool may attempt one of the following: |Check|DC|Result| |---|---|---| |Arcana|15|Recognises the pools as psychic repositories used to share information throughout the colony.| |Investigation|14|Identifies a recurring image of an immense brain suspended within a cavern of glowing fluid.| |Wisdom Saving Throw|DC 15|Resist the psychic impressions while viewing the memories. On a failure, the character takes 2d6 psychic damage but still sees the vision.| --- ## Information Learned The players discover: - The Elder Brain is physically present within the colony. - Every mind flayer is mentally linked to it. - The Brain is housed in the deepest chamber. - Large numbers of illithids are gathering elsewhere in response to the escape. This should naturally lead the players to conclude that destroying the Elder Brain is likely the only way to stop the colony. --- # Scene 4 – Maintenance Tunnels To avoid the increasingly active patrols, the party discovers narrow maintenance passages running beneath the hive. These tunnels are cramped, damp, and rarely used by intelligent creatures. They carry nutrient fluids, waste material, and biological growth between chambers. The tunnels provide a safer route but introduce environmental hazards instead of enemies. Possible hazards include: - Bursting nutrient sacs that spray acidic enzymes. - Tendrils that instinctively grasp warm creatures. - Sections of contracting muscle that threaten to trap characters. - Psychic spores that induce brief hallucinations. Each hazard should require a single check to overcome without significantly delaying the adventure. They reinforce the hive's alien nature while giving the players a brief respite from patrols. --- # Transition to Act III The maintenance tunnels eventually emerge onto a high organic ledge overlooking an immense cavern. Below, hundreds of translucent incubation pods surround vast pools where illithid tadpoles writhe beneath the surface. Thralls move silently between the pools under the supervision of grimlock handlers, while prisoners await the final stages of ceremorphosis. The characters have reached the colony's nursery. They are hidden for the moment, but any further progress will require confronting the defenders below. This marks the end of the infiltration and the beginning of the adventure's largest combat encounter.
