Castle High drops players into a boarding school built into a castle that never touches the ground, drifting between skylands that were lifted into the sky centuries ago by mysterious crystals called skyshards. The campaign frame is part magical school story, part coming-of-age mystery, and every classroom, tower, and distant ruin along the way deserves a battlemap to set the scene.
1. The Courtyard — College Campus
From the school’s own halls to the mysterious skylands drifting beyond it, these battlemaps are our top picks for bringing Castle High alive at your table.
The Courtyard is Castle High’s social hub, where students can eat lunch, trade gossip, and show off their broom tricks between classes. Lately, however, it’s also become the site of a minor scandal, after someone defaced a statue of the school’s mysterious founder with accusations.
This College Campus map gives players a lively gathering place to hang around in, with a ball court, cafeteria, and lecture hall all within reach for staging everything from a practice match to a full lunchtime scene—plus plenty of room to overhear rumors or kill time before the plot picks back up.
The campus map captures Castle High’s grand lecture halls and busy courtyards, but for a closer look inside the classroom, this animated Quaint Village School illustration paints a warm, cozy space perfect for lessons and study sessions.
2. Saelor’s Stadium — Magical Tournament Arena (Four Elements)
Saelor’s Stadium fills with thundering crowds for every event—bands blasting in bold uniforms with hot dogs and popcorn thrown about. An off-campus skyland built for spectacle above all else, it’s the venue for Castle High’s sports, duels, and competitions.
The four elements variant of this Magical Tournament Arena map isn’t your typical bleachers-and-field stadium, but it’s a striking match for the tone of this frame, with platforms around the edges that could double as team stations if you’re leaning into the rivalries between the four towers
3. Cloud Nine Diner — Inner City Bar
The Cloud Nine Diner never closes, and it never quite feels like it belongs to any one place and time. Sky shippers gather at the counter to swap stories, the jukebox belts out fortunes along with the latest hits, and the no-nonsense waitress running the place might be hiding a secret of her own.
This Inner City Bar map gives the diner an electric atmosphere, with its neon glow and sprawl of booths making it easy to imagine your players catching their breath between adventures.
4. Clerestory — Solar Cathedral
The Clerestory is where Castle High’s students come to pray, take Splendor courses, and—a little less reverently—carve their initials into the pews. Sunlight pours through its intricate stained glass windows, which hold three words no one’s ever managed to translate.
This Solar Cathedral map lines up beautifully with that description, from the glowing stained glass to the rows of well-worn pews below. The map also includes an upper level that adds even more to work with, with a massive organ and prayer corners tucked away from the main hall.
5. Library — Great Library
The Library holds books, maps, and a computer room that might be older than the castle itself… along with at least one resident ghost, said to trade you a secret if you’re willing to share one of your own first. Codex courses also meet regularly among its collections.
This Great Library map set more than earns its spot on this list, with seven maps and variants covering the orrery, reading halls, study nooks, and even a bestiary. It’ll give any GM tons to work with, whether your players are here to study, dig up old records, or track down some ghost gossip.
6. Skyport — Beach Town (Skytown Ships)
With so many cities and islands scattered across the sky, ports of some kind are sure to exist, giving airships somewhere to dock and weary fliers somewhere to stop between the skylands.
The skytown variant of this Beach Town map is an excellent fit to slot into your campaign when your party needs somewhere to rest between skybound adventures, with lively market streets and a view of the open sky just past the boardwalk. Use it as a resupply stop along Castle High’s yearly route through the clouds, or a dorm town for off-campus living.
7. Flying Mount Stables — Hippogriff Postal Center (Sky)
Flight is a required skill at Castle High, but skyshard brooms can only cover so much ground. Somewhere on campus, the school also needs a proper place to house its winged mounts, with stalls, feed, and plenty of room to land and take off.
The sky variant of this Hippogriff Postal Center map can be repurposed from its original theme as a stable for Castle High’s own hippogriffs and other flying mounts. You could also just as easily keep its original purpose, though—with the skylands scattered so far apart, the students need some way to send letters and packages home.
8. Akroepis — Flooded Fey Ruins (Sky Temple)
Toppled columns and cracked pillars sit alongside broken aqueducts and basilicas at Akroepis, where peacocks roost in lush branches, and waterfalls never seem to run dry. Built long ago during the age of the Forgotten Gods, the ruins remain in remarkable shape despite their age—though the labyrinths hidden within them have swallowed more than a few archaeologists who came looking.
This Flooded Fey Ruins map gives this mysterious location all the gravitas it deserves, a strong pick for a skyland built to reward curiosity while punishing carelessness in equal measure.
9. Krawl — Castle Battlements (Sky)
Moss crawls across Krawl’s derelict keeps and crumbling castles, and its ruins are said to invert whenever a bell rings out of nowhere. Once home to a violent king, the stone itself seems aware of anyone who wanders in, shifting its walls to trap explorers inside alongside the remains of warriors who never made it out.
This Castle Battlements map fits the weight of all that history, its weathered stonework and long, torch-lit shadows that give the whole place the right feeling for a dungeon-crawl in a skyland where the fortress itself is an enemy
10. Tirnish — Remains of Advanced Society
Overgrown skyscrapers and tarnished chrome define Tirnish, where pigeons nest in old satellite dishes and rows of cars sit abandoned in the streets. Nobody knows the real story behind what happened here—though the radioactive elementals and smiling zombies wandering its ruins might have something to do with it.
This Remains of Advanced Society map does exactly what it needs to: it’s equal parts mysterious and unsettling, with drowned streets and collapsed infrastructure hinting at a sudden abandonment (or extinction event) rather than slow decay.
11. Open Skies — Midair Dragon Flight
Flying is part of daily life at Castle High, and the book leans right into its danger and thrill. One bit of GM guidance even suggests having a student nearly get eaten by a dragon mid-flight—just a sign of how wild the open sky can get.
This Midair Dragon Flight map set gives GMs a ton to work with for any travel scene through the clouds, with 36 modular maps to piece together in a flight path of your own. It’s a great fit for the sunny, reckless joyrides characteristic of this frame—as well as for the moments when that joyride takes a turn into danger.
