The party dies in the first room. Then they wake up at the dungeon entrance. Again. And again. Trapped in a time loop inside an ancient crypt, they must piece together the correct sequence of actions across multiple "runs" to break the cycle and escape alive.
Story Arcs
Dying to Get Out
The adventurers enter an ancient crypt seeking treasure and find death — quick, unavoidable death. But death doesn't stick. They snap back to the entrance, memories intact, forced to try again. Each loop reveals new information: a pattern in the traps, a ghost who speaks only on certain runs, a door that only opens if a specific action was taken three rooms ago. The crypt is a puzzle box and death is just the reset button.
Session Outlines
These outlines are for planning reference only. Actual sessions are not created by the template.
The Groundhog Crypt
LOOP 1 (15 min): Players enter the crypt confidently. Room 1 has a riddle on the wall they'll probably ignore. Room 2 has a trapped hallway — someone dies. Room 3 has a locked door. Room 4 has an overwhelming fight. They die. SNAP — back to the entrance. Describe the disorientation. LOOP 2 (20 min): Now they know what's happening. They pay attention to the riddle (it describes a sequence). They avoid the trap. The locked door still won't open. The fight is still unwinnable. They die again but lasted longer. LOOP 3 (25 min): The ghost of the crypt's architect appears (only on odd-numbered loops). She gives cryptic advice: "The order matters more than the outcome." Players realize the riddle describes which rooms to visit in which order, and that actions in one room affect others. LOOP 4 (30 min): Players attempt the correct sequence. Visiting Room 3 first (before Room 2) changes the trap. Solving the riddle in Room 1 gives a keyword that opens the locked door. The overwhelming fight becomes fair if the keyword is spoken. LOOP 5 (30 min): Final run. Players execute the correct sequence. The crypt opens its final chamber — the time loop was a security system protecting the real treasure. The architect's ghost is freed and thanks them. Optional: she offers a dark choice — reset the loop and trap the next intruders, or destroy the crypt forever.
NPCs
Architect Senna Vaal
Ghost (Human) · Crypt Designer
The ghost of the brilliant but obsessive architect who designed the time loop crypt as her masterpiece. She appears only on odd-numbered loops, initially as a translucent figure who speaks in riddles. She is bound to the crypt and desperately wants the loop broken so she can finally rest. She cannot directly tell the players the solution (the crypt's enchantment prevents it) but she bends the rules as far as she can with cryptic hints. In life, she was a perfectionist who spent 40 years building this crypt and died inside it, becoming its first victim.
Kravik the Undying
Wight · Guardian of the Final Chamber
The crypt's primary combat guardian, a wight bound to the time loop just like everything else. In the wrong sequence, he is nearly invincible — regenerating health, summoning skeleton reinforcements, and fighting with relentless precision. In the correct sequence (keyword spoken, rooms visited in order), his power is halved and his reinforcements don't arrive. He has no personality — just cold, mechanical duty. Defeating him is the final test.
Locations
The Crypt of Repeating Halls
An underground tomb of polished black stone with silver inlay that seems to shift when you're not looking directly at it. The air tastes of old magic and copper. Four main chambers branch off a central atrium. Each room changes subtly depending on the order in which they're visited — details that only become apparent after multiple loops. The entrance seals behind the party every time.
The Riddle Atrium
The first room: a circular chamber with the riddle carved in silver letters across the domed ceiling. The riddle reads differently each loop — not because it changes, but because the players notice new lines they missed before (Perception DC increases reveal hidden text). A mosaic on the floor shows four rooms connected by arrows in a specific order.
The Shifting Trap Hall
A long corridor of pressure plates, dart launchers, and swinging blades. When visited second (the wrong order), the traps are lethal and unavoidable. When visited third (the correct order), half the traps are already triggered and the rest can be disarmed. The wall sconces light in a pattern that hints at safe tiles.
The Sealed Door
A heavy stone door with no handle, no keyhole, and no visible mechanism. Speaking the keyword from the Riddle Atrium causes it to grind open. Behind it lies a short passage to the final chamber. Carved into the door frame is a single sentence: "Only the worthy sequence earns passage."
The Guardian's Chamber
A vast burial hall with a raised sarcophagus at its center. Kravik the Undying emerges when intruders enter. The room's difficulty scales with how many rooms were visited in the correct order — torches light to show the party's "progress." The treasure vault is behind the sarcophagus, sealed until Kravik falls.
Quests
Break the Time Loop
The crypt resets every time the party dies or fails. Piece together the correct sequence of rooms from the riddle, the ghost's hints, and observations across multiple loops. The solution requires visiting rooms in a specific order — each visit changes the conditions of the next room.
Free Architect Vaal
The ghost of the crypt's architect has been trapped in the loop for centuries. Breaking the loop frees her — but she offers a choice at the end: reset the trap for future intruders (preserving her legacy) or destroy the crypt forever (granting her true rest). The party decides.
Encounters
Kravik the Undying (Wrong Sequence)
Kravik at full power: regeneration, skeleton reinforcements, and legendary actions. This fight is designed to be unwinnable, forcing a loop reset. Players should realize quickly that brute force alone won't solve this dungeon.
Kravik the Undying (Correct Sequence)
With the correct sequence completed, Kravik fights at diminished power — no regeneration, no reinforcements. Still a challenging fight for a level 3-5 party, but fair and winnable. His defeat breaks the time loop permanently.
The Trap Hallway
A gauntlet of mechanical and magical traps. Dexterity saves, Perception checks, and creative problem-solving determine who survives. In the wrong sequence, the traps reset faster than the party can move through.
