Level 9 - Serpent Shrine

Overview

A circular shrine of green stone and gold, built in the style of Eastern alchemical temples. Eight carved stone pillars ring a raised central dais where an enormous golden serpent lies coiled — alive, awake, and watching. Mercury channels pulse between the pillars like silver veins. Display cases along the outer walls hold ornamental ritual weapons. An open grimoire rests on a stone altar. The air smells of metal and incense.

Unlike previous levels, the guardian here does not wait to be provoked. The moment the party enters, the Gilded Serpent raises its head and speaks — in Parseltongue.

Room Layout

Central Dais: Raised stone platform where the Gilded Serpent coils. Surrounded by alchemical flower beds — cinnabar flowers (deep red), mercury moss (silver), and jade lotuses (pale green). The flowers still bloom after four centuries, sustained by the same enchantment that powers the serpent.

Stone Pillars (8 in a ring): Carved with coiling serpent reliefs and Eastern alchemical symbols. Connected at the base by channels of liquid mercury that pulse with silvery light. The pillars anchor the enchantment that animates the Gilded Serpent. During combat, a pillar can be toppled (Athletics DC 15 or sufficient damage — AC 15, 20 HP) to weaken the serpent: each destroyed pillar reduces the serpent's AC by 1 and HP maximum by 10.

Display Cases (8 around the outer wall): Each contains an ornamental ritual weapon on red velvet — Seylon's collection of Eastern alchemical implements. Plaques beneath each in Eastern script (Comprehend Languages or DC 14 Arcana to read). These are ceremonial, not functional — except the Serpent's Fang Dagger (see Treasure).

The Altar (south): Stone pedestal with an open grimoire — Seylon's notes on Eastern serpent-dragon alchemy and the prophecy that inspired this room.

Bookshelf (northwest): Eastern alchemical texts, scrolls attributed to Quong Po, and letters from an unnamed Eastern colleague.

Stairs (southwest): Entry from Level 8.

The Gilded Serpent

Personality

Ancient, formal, mournful. It refers to Seylon as "my creator" and "the Grieving One." It does not know Seylon is dead. It has been waiting for "the one who speaks as serpents do" for four hundred years. It is patient but not infinitely so — prolonged silence or hostility will be met with force.

Stat Block

Reskinned Red Dragon Wyrmling (CR 4). Use only if combat triggers.

• AC 17 (gilded alchemical scales)
• HP 75 (10d8+30)
• Speed 30 ft, climb 30 ft
• STR 19 (+4) DEX 10 (+0) CON 17 (+3) INT 12 (+1) WIS 11 (+0) CHA 15 (+2)
• Type: Construct
• Immunities: Poison damage, poisoned condition, charmed, frightened
• Senses: Blindsight 10 ft, darkvision 60 ft
• Languages: Understands all languages, speaks only Parseltongue

Bite: +6 to hit, reach 5 ft, 2d6+4 piercing damage.

Mercury Breath (Recharge 5-6): 15-ft cone. DC 13 Dex save. 7d6 poison damage on a failed save, half on success. The liquid mercury spray coats the ground — affected area becomes difficult terrain for 1 round.

Minions: On initiative count 20, 1d2 Flying Snakes (CR 1/8, MM p.322) drip from the serpent's coils as globs of mercury that animate into small snake forms. Max 4 active at once. All minions are destroyed when the Gilded Serpent is killed or pacified.

The Trial

The Language Barrier

The serpent speaks only Parseltongue. It understands all languages (players can answer in Common), but the questions themselves must be comprehended. Ways to understand:

• Tongue of All Things mushroom from Level 8 (Comprehend Languages, 1 hour) — if still active, this works perfectly
• Natural Parseltongue — anyone who speaks it understands automatically
• DC 15 Arcana check — gives a rough sense of the meaning (DM paraphrases imprecisely: "It seems to be asking about... why this place exists?")
• Total failure — if no one can understand after 3 attempts (serpent repeats each time, more slowly), it grows agitated and attacks

The Greeting

The serpent lifts its head, mercury eyes flickering to life:

"At last... visitors. My creator promised you would come. Tell me — do you come to continue the Great Work, or to destroy it? I will know the truth."

This is rhetorical — the serpent proceeds to ask its questions regardless of the answer. But hostile responses ("We're here to destroy everything") will put the serpent on edge.

The Questions

The serpent asks four questions, one at a time. It waits for an answer before proceeding.

Question 1 — The Purpose:

"Why did the Grieving One build this tower?"

Question 2 — The Daughter:

"What was her name — the one for whom all this was made?"

Question 3 — The Cost:

"What did the Grieving One sacrifice in his pursuit?"

Question 4 — The Judgment:

"And was he right to do so?"

This is a trick question. There is no wrong answer. The serpent accepts any sincere response — "Yes," "No," "I don't know," "It depends." It nods slowly regardless.

"My creator said you would be honest. That is enough."

This mirrors the tower's central theme: was Seylon's obsession justified? The serpent was programmed to accept honesty, not a specific moral position.

Trial Outcomes

Passed (0-1 wrong answers): The serpent bows its head. "You may ascend. Continue the Great Work... for her." The stairway to Level 10 opens. No combat. The serpent remains as a passive guardian — it may speak again if they return.

Failed (2 wrong answers): The serpent gives a final warning. "You test my patience. One more misstep and I will protect the Great Work as I was made to." One more wrong answer triggers combat.

Failed (3+ wrong answers or total communication failure): The serpent rears up. "You are not the ones who were promised. You are the destroyers." → Combat.

Combat

Triggered only if the trial fails or the party attacks first.

Tactics

• The Gilded Serpent stays near the dais, using reach and Mercury Breath to control the center of the room
• Flying Snake minions harass backline spellcasters
• The serpent prioritizes whoever answered questions incorrectly (it remembers)
• If reduced below 25 HP, it coils defensively and speaks: "Is this how the Great Work ends? In violence?" — a final chance for the party to stand down

Pillar Destruction

Each destroyed pillar weakens the serpent (AC -1, HP max -10). Destroying 3+ pillars causes the serpent to visibly flicker and dim. This gives the party a tactical alternative to pure damage.

Emergency Pacification

The altar grimoire contains a backup passage (DC 14 Investigation to find mid-combat):

"Should the guardian turn against its purpose, speak these words: 'Lyra sleeps, and so shall you.'"

Speaking this phrase (in any language) forces the serpent to make a DC 15 Wisdom save. On a failure, it goes dormant for 1 minute — enough time to reach the stairs. On a success, it is stunned until the end of its next turn.

The Prophecy

Among the grimoire's pages on Eastern alchemy, one passage stands out:

"The seer in the East spoke words I cannot ignore: 'One who speaks the serpent's tongue shall come to your tower when the stars grow cold. They will complete what grief began.' I do not know when. I do not know who. But I will prepare for them. The guardian will test their heart, and if they are worthy, they will carry my work forward."

"I have keyed the guardian to the serpent's tongue because the prophecy demands it. It will speak as they speak. It will know their intent."

A margin note in shakier handwriting:

"Theo says the prophecy is a trap. He says completion does not mean what I think it means. But what choice do I have? If there is even a chance..."

DM Notes on the Prophecy

The prophecy is deliberately ambiguous. "Complete what grief began" could mean:

• Finish Seylon's resurrection research (Seylon's hope)
• Destroy the tower and end his legacy (Theo's fear)
• Use the relics for dark purposes (what Bellatrix's Children intend)
• Something the players themselves decide

Primrose Calloway is an unknown Parseltongue — she doesn't know this about herself. If she reaches this level (manipulated by fake Harry letters from Bellatrix's Children), she would pass the language barrier effortlessly and likely answer the questions correctly given her obsessive knowledge of Hogwarts history. This is what makes her the perfect pawn: she's uniquely suited to access the tower's deepest secrets.

The party should eventually realize the terrifying implication: the prophecy's "serpent speaker" might be Primrose, and the Death Eaters know it.

Treasure

• Serpent's Fang Dagger: +1 dagger from one of the display cases. Once per long rest, on a hit, the target must make a DC 13 Con save or be poisoned for 1 minute. The blade shimmers like liquid mercury.
• Quong Po's Egg Treatise: Scroll on Chinese Fireball egg properties. Worth 75 gp to a collector or alchemist. Grants advantage on one Alchemy-related check.
• Alchemical reagents: 3 vials of liquid mercury (15 gp each), pouch of cinnabar powder (25 gp), one Chinese Fireball eggshell fragment (50 gp, glows faintly crimson-gold)
• 2x Potion of Healing (in jade vials, tucked behind the bookshelf)

Lore & Clues

Seylon's grimoire (altar):

• "What the East has known for centuries, our Western scholars ignore: the serpent does not die. It sheds its skin and is reborn. If I can master this principle, Lyra need not remain in death's embrace."
• "Quong Po's work with Fireball eggs revealed the blood of dragons carries the same mercury-essence. Fire and rebirth. The serpent and the dragon are one."
• "I have built the guardian in the Eastern fashion — a Liondragon of gold and mercury, as the Chinese masters described. It will protect this chamber until the one who was promised arrives."

Bookshelf — letter from an unnamed Eastern alchemist:

• "Honoured colleague — I share your grief but not your conviction. The Rite transforms matter, not souls. Mercury bridges states of being, but death is not a state. It is an absence. I urge you to reconsider."

This is the first direct evidence that someone outside Hogwarts warned Seylon his research was futile — mirroring Theo Turner's warnings from a completely different magical tradition.

Atmosphere

The room smells of metal and incense. Mercury channels between the pillars pulse like veins, casting silver reflections on the green stone. The flower beds bloom with impossible colors — cinnabar red, jade green, mercury silver. The golden serpent's coils catch the light like a temple statue. Everything feels ancient and sacred, more shrine than laboratory. The serpent's voice, when it speaks, resonates through the stone — low, ancient, and unbearably sad.
