Summary
The party discovers they have been transported inside a massive, living Tarrasque — a legendary creature of apocalyptic power. The "shortcut" to Neverlight Grove led them into the creature's body. The session is dominated by combat encounters with parasitic creatures, dangerous anatomical passages, and desperate survival. The party encounters evidence of previous explorers and discovers a mysterious dwarf survivor still alive within the creature. Session ended with party split and navigation uncertain.
Key Events
The Tower Discovery and Realization
- Party encounters a fallen/partially destroyed research tower from the "Society of Brilliance"
- Tower is lodged within the creature's flesh; contains a book relevant to the Society of Brilliance
- Critical Realization: The "cave" is actually made of flesh. Walls and floors suddenly tilt to 45-degree angle; party realizes they're inside a living creature
- Party takes damage from the tilt and resulting falls
- GM describes the shock as discovering a "towering, gaping, sucking flesh wound" into the creature
- Stool (young mykonid) was unreliable as a guide: the shortcut was actually a mistake or trap
Anatomical Choice and Path Forward
- Party discovers two possible paths:
- The Stomach (described as more dangerous)
- The Lungs (chosen path)
- Caspian dashes ahead while the lungs are inhaling; party shaken by inhalation/exhalation movements
- Party finds graffiti written by someone named "Skris" on the walls (identity unknown; may be previous explorer)
- Party realizes navigating inside the creature will be extremely dangerous
Combat 1: Dire Roundworms in the Lung Chamber
- Enemies: Two parasitic dire roundworms with horrifying anatomy
- The Threat: One roundworm grapples Selene
- Creature's mouth functions like a suction mechanism with "a whirl of teeth like the Langoliers"
- Threat: Creature will suck out her guts with its straw-like mouth
- Escape requires DC 15 Athletics or Acrobatics check (uses action)
- Critical Danger: If successful, creature will "suck her guts out from her fucking straw"
- Revivify Limitation: If the creature eats her organs, her body would be gutted; Revivify won't work
- Combat Actions:
- Othorion: Makes successful melee attack; kills at least one worm
- Kefkas: Uses Disarming Strike; deals damage to the creature
- Selene: Can use Scroll of Raise Dead if she dies (provided by Kefkas)
- Outcome: Party successfully kills both roundworms and frees Selene before full extraction
Lung Inhalation and Exhalation Cycle
- The lung inhales, creating a strength save (DC 13) with quick-time button-mash events
- Successful Saves: Roland, Caspian
- Failed Saves: Othorion (goes prone; knocked down again when standing), Selene, Kefkas
- Quick-time events require repeated strength checks with matching button sequences
- Comedic Moment: One quick-time sequence has letters spelling "suck my dick" on purpose; Selene fails despite understanding the reference
- Lireal casts healing on Selene ("try not to get sucked up like a slurpy straw")
Combat 2: Mouth and Tongue Chamber
- Party moves into or near the creature's mouth
- The Pitons and Rope System: The gum line has pitons and rope tied throughout as anchors
- Anatomical Danger: The creature's tongue starts thrashing, trying to eject items/people
Tongue Attack Sequence
- Haldak: Gets jammed by the tongue against creature's teeth; takes 13 bludgeoning damage
- Othorion: Makes dexterity save and succeeds; avoids tongue impact
- Haldak's Response: Uses Misty Step; teleports 30 feet to grab pitons on the gum line while still holding rope
- Movement Challenge: Gum line is difficult terrain (half speed); Haldak and Othorion navigate carefully
- Irritation Damage: Being in the creature's mouth causes irritation each round
The Esophageal Launch and Rescue
- Strength Saves (DC 13) for continued tongue attack:
- Kefkas's Heroic Catch: Makes Dexterity save (DC 14) to catch Othorion before he fully enters the esophagus
Wedged at the Esophageal Sphincter
- Location: Othorion is wedged at the sphincter between mouth and stomach
- Acid Exposure: Being stuck at the sphincter causes acid splash; Othorion takes 6 acid damage
- DC 12 Athletics Check: Othorion must hold against esophageal undulation
- Success: Othorion holds despite taking damage and danger of dropping into the stomach
Discovery of the Mystery Dwarf
- Kefkas and Haldak find a dwarf in the esophageal passage/hallway
- Description: Missing an arm; acid-eaten stump with exposed bone barely alive
- Appearance: Art token with squinty, sleepy eyes; appears disheveled
- Speech: "Oh, company." (then passes out immediately)
- Implication: This dwarf has been trapped inside the creature for an unknown duration; may possess critical information about survival or escape
- GM Description: Imagined as "bone with acid-eaten arm," not a clean amputation
Secondary Rope Team Preparation
- The Plan: Party members still outside the creature decide to descend into the mouth to rescue those trapped inside
- Rope Organization:
- Kavu ties knots for safety (with some party members questioning his knot-tying ability based on past failures)
- Party waits for the creature to exhale before descending (exhalations occur every 6 seconds)
- Slowest movement speed in group is 30 feet (likely Stool or another character)
- Most party members can move 30-40 feet per round
- Healing During Preparation:
The Rope Descent and Navigation Challenge
- The Rope Train: Entire remaining party (tied together) begins descending into the creature's mouth
- Movement: Groups moves as one unit at slowest member's speed
- Entry Challenge: As Roland reaches the end of rope descent, he encounters an intersection
- The Problem: Rushing fluid moves in multiple directions; party doesn't know which way leads to safety
- Navigation Failure: Party is uncertain which direction to proceed; they are effectively lost inside a living creature with multiple flowing passages
- Potential Solutions Discussed:
- Should they use Locate Object spell to find trapped companions?
- Are they going "with the flow" or resisting?
- Which direction is actually safe?
- Session Ends: Party faces critical navigation decision with uncertain outcome

- Skris Graffiti Identity: Who is Skris? Trapped explorer? Active explorer? Other survivors inside the creature?
- Navigation Inside the Tarrasque: Multiple questions — is there a way out? What is creature's destination/purpose? How far to travel? Can they kill it from inside? Should they seek exit or cure?
- Society of Brilliance Mystery: Why was tower here? What research were they conducting? Other information in tower? Other outposts?
- Creature Parasites and Ecosystem: Are there more dire roundworms? Other creatures living inside? What is the creature's internal ecosystem? Can parasites be eliminated or avoided?

Summary
Session C09 is a massive, chaotic survival scenario inside a legendary Tarrasque creature. What was meant to be a shortcut to Neverlight Grove became a horrifying discovery that the party is inside a living, conscious creature. Parasitic creatures, digestive systems, acid damage, and mysterious previous victims create multiple layers of danger. The session is dominated by combat encounters, quick-time events with physical difficulty checks, and desperate navigation through anatomical systems.
The party is currently split: some members deep inside the creature (esophageal passage and beyond), others descending via rope to effect rescue. The discovery of a Skuld (mystery dwarf, later found dead) and the presence of "Skris" graffiti suggest that the creature has been consuming victims for a significant time, and that previous explorers have attempted to navigate or escape its interior.
The session ends with the party facing a critical navigation challenge: multiple flowing passages, uncertain direction, and the threat of becoming lost inside the creature. The scope is apocalyptic; a Tarrasque is a world-ending threat, and being inside one represents an existential danger level far beyond typical dungeon exploration.
Critical Story Developments:
- Party trapped inside a living Tarrasque creature
- Multiple casualties/separation of party members
- Discovery of Skuld (mystery dwarf, later found dead) (provides hope, raises questions)
- Rope system established for rescue but navigation uncertain
- Previous explorers/victims confirmed inside (Skris, other remains)
- Evidence suggests Society of Brilliance had knowledge of creature
- Entire shortcut to Neverlight Grove may have been creature's trap or catastrophic mistake
