The Star-Spangled Spire: A July 4th DnD One Shot for Small Groups

The Star-Spangled Spire is a patriotic July 4th DnD one shot for small groups of 2-3 players at Levels 2-3, built to run in a single 2-3 hour session with no advance preparation. Anvil N Ink Publishing released the 107-page adventure for Game Masters who want a holiday one-shot they can pick up Saturday morning and run that night — not adapted from a heavier module, not researched ahead for next year, but built specifically to be played on the Fourth of July with a small group. The premise is direct: at the top of the Star-Spangled Spire on Sovereignty Day, a tax collector named Ambrose Grenville is about to ring a bell that will end the Republic. The party has until midnight to stop him. Everything needed to run the session — encounter math, battle maps, stat blocks, pregens, contingencies — is on the page.

What Makes This a Patriotic 5e One-Shot That Earns Its Holiday

The Star-Spangled Spire takes the Fourth of July seriously without taking itself too seriously. Set in the city of New Providence on its 247th Sovereignty Day, the adventure builds a Republic founded by thirteen cities signing a covenant at the foot of the Spire. Fireworks bloom over the harbor. Citizens crowd the festival streets. Sparklers in tricorn hats, brass bands in plazas, the whole apparatus of an old democracy celebrating its survival. The book grounds the holiday in fantasy without leaning on heavy-handed analogy.

A Villain You Almost Agree With

The antagonist, Ambrose Grenville, is not a cackling cultist. He is the last Collector-General of the Crown’s Tithe — a dignified believer whose grandfather was hanged at the founding, who has spent forty years studying the question of whether the Republic was a mistake, and who has reached a conclusion he intends to act on. The Spire’s Celestial Orrery, an ancient mechanical model of the heavens, can be made to reverse course at the precise instant the Bell of Sovereignty strikes midnight. Grenville’s argument with the party is the moral spine of the adventure. He is wrong. He is also not stupid. The book gives him the dignity of a real position, which makes stopping him feel like something more than killing a monster.

Stakes That Stay Concrete

The bell hangs at the top of the Spire. It is going to ring at midnight unless someone climbs the Spire and stops it. The party has a finite number of rounds. The book never abstracts the stakes into prophecy or planar metaphysics — every act ends with the question of how much time is left and whether the next obstacle is worth a round to clear.

What’s Inside This 107-Page July 4th DnD One Shot

The Star-Spangled Spire packages the full adventure into 107 pages of self-contained, ready-to-run content:

• A four-act structure designed for a single 2-3 hour session at the table
• Encounter math sized for 2-3 player characters at Levels 2-3 — stress-tested for the worst case of two characters at level two
• An optional Path A / Path B fork in Act Two, with both routes documented at the same level of detail
• 8 detailed battle maps covering every major encounter, from the festival-street Entrance Plaza to the Celestial Balcony boss arena
• 5 full SRD 5.1-compatible creature stat blocks: Redcoat Sentinel, Scarlet Lieutenant, Alchemical Sentinel, Loyalist Bodyguard, and the haunting Cistern Horror
• A three-phase boss fight with legendary actions, allowing the villain to evolve across the encounter
• 4 pre-generated characters — fighter, rogue, warlock, cleric — with full backstories, equipment, spells, and roleplaying notes
• 6 opening hooks for any campaign, plus 6 closing hooks for groups who want to keep playing past midnight
• A “What If?” appendix that names the player decisions that derail the plot — and addresses each one
• A complete Aftermath section with per-ending epilogues for every reasonable outcome

The Central Choice — Path A or Path B

At the end of Act One, the party reaches the Bell Chamber and faces the adventure’s structural fork. They can ring the Bell themselves to flood the Spire with silver light and activate magical shortcuts that bypass several encounters — a louder, faster, more action-heavy route. Or they can descend through a grate in the floor into the Sealed Cisterns and reach the summit through Grenville’s blind spot — a quieter, darker, mystery-heavy route past the ghost of a long-dead courier still trying to deliver his last message.

Both paths converge at the Spire’s industrial heart in Act Three. The choice does not branch the rest of the adventure into separate manuscripts; what it does is change the texture and the difficulty profile. Action-heavy groups will gravitate toward Path A. Investigation-heavy groups will gravitate toward Path B. The book documents both routes with the same care, and either ends the same way: at the foot of the staircase to the Celestial Balcony, with six rounds until midnight.

Built for Busy Game Masters

The Star-Spangled Spire is built for a Game Master who got the book on Saturday morning and needs to run it Saturday night. Every encounter is balanced for a small group at second or third level. Every clue and skill check is documented in the act where it matters, not buried in an appendix. Every difficult decision the party can make is addressed in the “What If?” section — what if they ring the bell themselves, what if they pickpocket Grenville before the fight, what if they side with him, what if they break the Orrery instead.

The pregens are sheet-ready, with backstories already woven into the adventure. The opening hooks let the GM drop the Spire into any campaign or run it as a standalone. The closing hooks give a campaign-continuation path if the group wants to keep playing past midnight. The book respects the Game Master’s time.

Perfect for Your July 4th DnD Game Night

The Star-Spangled Spire is built specifically for the following play situations:

• Independence Day and Fourth of July game nights. A holiday one-shot designed to actually be run on the holiday — patriotic without preaching, celebratory without being shallow.
• Game Masters with a small group. Built from the ground up for 2-3 players, not adapted down from a four-player module. Encounter math accounts for short PC counts and missing role coverage.
• Couples and duet players. Two characters at level two can finish this adventure. Pregen viability has been verified for any two of the four pregens together.
• GMs who hate prep. A complete one-shot with all stat blocks, battle maps, and contingencies on the page. No external references, no SRD lookup, no balance math at the table.
• Players who want fireworks and brass automaton soldiers. And a moral dilemma. And a villain you almost agree with.
