The BackHalls

This page is about the demiplane, for the campaign named after the Demiplane, see The BackHalls (Campaign)

The BackHalls (Real name unknown) were a mysterious and seemingly unending labyrinth of hallways and office spaces, where the only companions you'll find are the comfort of the damp carpet under your feet, and the buzz of the florescent lights above. Creatures from all manner of time and space found themselves in the BackHalls fighting for survival.

History

Prehistoric Article This article contains information said to be from Prehistoric Times. The validity of prehistoric content is dubious at best due to poor recordkeeping in the era, and should be considered unreliable, or at best: Legend.

It was rumored that the BackHalls were created in prehistoric times by a legendary warden known as Ymbtry (the same warden which the town Ymbtrymman is named for), who had created the demiplane as part of a lost magical ritual which he called "The Blackened Hallmark".

After its creation, very few, if any, creatures ever escaped back to Quelmar from the BackHalls. As a result, its long history is compressed into a compressed time in which it seems everything is happening everywhere at once.

It was confirmed that the BackHalls (much like other planar links) were destroyed as part of the Fracturing of the Weave, and the contents of the halls at that time were dumped out across Quelmar, including whatever power was left of its Vestiges, who added to the apocalyptic vibes of the fracture.

About

Creatures (or objects, magic, plants, really anything that can be targeted by a spell) enter the BackHalls when they are subjected to imprisonment magic, but the spell was not done in the correct way -- either on purpose or due to a lack of skill. As a result, the target of the spell is teleported and imprisoned not in a typical imprisonment bubble, but to this nullified demiplane that exists tangential to reality. Since it was inescapable, it would later become a secret among mages to cast Imprisonment incorrectly if you REALLY needed to get rid of something for good, such as a piece of blackmail, or a curse, or something else that threatens the realm.

Spawning

The BackHalls has specific rooms that are "spawn rooms" where creatures will appear to be summoned out of nowhere. Typically once a spawn room has summoned a party of creatures, it will have a cooldown period before it summons more creatures. Every time a creature spawns, they will be carrying whatever they had on their person when they were originally subjected to the imprisonment, including their clothes, weapons, and any satchels/inventory they had on their person.

When someone is killed in the BackHalls, they do not die, but rather respawn in the halls in a new spawn room. However, they will not retain any memories, items, or powers from their prior life cycle. As a result, every time someone spawns into the BackHalls, they will feel like it is the first time they've ever spawned in the BackHalls.

Life in the Halls

The souls banished to the BackHalls never needed to eat, sleep, or drink. They don't get physically sleepy, but may find themselves wearing thin on abilities and power (such as magic) as they exhaust their power, requiring them to still rest for a time to regain natural strength.

Architecture

The walls of the BackHalls were said to be covered in an offensive wallpaper of beige and yellow colors, featuring vertical columns of repeating fleur-de-lis. There were no doors in the hallways, only open passages, though whether or not there were historically any doors is an open question, considering that wooden debris could be found in various places.

Shops

Every 42nd Room in the BackHalls was home to a strange shop. Shops came in all shapes, sizes, forms, and sold any number of weird things.

The economy in the BackHalls was based off of Trinkets and not money. Trinkets took the form of literally anything small and deemed valuable to someone in the halls. That could include true valuables like jewelry, as well as lesser valuables like portraits, books, weapons, parchment, hair, and all manner of strange left-behinds.

One shop wound up being a Stuckey's

• This specific shop was run by a recneck attendant named Zeke. He gave out temporary tattoos which granted powers such as Spell Slots, Action Surges, etc.
• The Stuckey's had mounted mirrors in the corners of the room like a gas station, but unlike normal mirrors, these also seemed to show spooky demons lurking around the room

The BackDoors

It was possible to enter the space between the walls using a crafted door. Attempting to magically or mechanically attach a door to any of the natural decaying mustard-yellow walls of the BackHalls will reveal an opening. Stepping inside the opening places you exactly on the other side of the wall, in an inky black abyss impossible to navigate, but literally on the other side of the walls. It's possible to quietly use this space between the walls to navigate the halls while avoiding detection, but like all good ideas, that means encountering similarly clever creatures who lurk in the darkness, either innocently sneaking by, or purposefully ready to ambush in the dark.

BackDoor Runic Chalk

Besides opening doors in the wall, another "Backdoor" way of travel was invented at some point in time. Using a special, limited availability, chalk -- one can draw a sigil on the ground that they believe only they understand. The chalk will then connect to any other identical sigils in the halls, opening a gateway. This could be used in a single "run" to create safe points or teleporation points, but it could also be used ACROSS runs to see where your past life has been. The primary users of the Runic Chalk were wizards and other spellcasters, who often times would decipher the mysteries of the halls quick enough to "re-discover" the chalk and find themselves in a cozy room they partitioned off, already full of the records and items and friends of their past lives.

Quirks & Tidbits

Many groups preferred to travel in groups of 10, called Contuberniums, due to it giving that group a sort of invincibility or invulnerability from The Allip.

Puzzles

Several Rooms have written puzzles placed on either the floor, or the ceiling, or even on a wall. The source of the puzzles is unknown, but it's been said that anyone who can solve the mysterious, anomalous puzzles will be instantly rewarded with treasure of some kind. Sometimes it's an instant refresher, sometimes it's a weapon or item, or sometimes it's exactly the answers you were looking for.

Doors

There was almost nothing as valuable as a free-standing Door in the BackHalls. Having a large door on wheels (a specialty of the Dwarven guild that lived in the halls) would allow groups to travel and close off passages behind them, or find a safe dead-end somewhere where they could close off the only passage in, providing a 100% guaranteed sanctuary.

Soundtracks

The BackHalls was full of an eerie buzz and a haunting silence, which was sometimes broken by distance screams, crunches, or other ghastly sounds of people dying. However, to remedy this, a number of shops in the BackHalls sold "Soundtracks", which could be purchased and activated to relieve the haunting silence, filling the air with all manner of music and noise. It was almost necessarily for long-time survival, as the haunting silence and constant reminders of death tended to drive others to insanity.

Some known soundtracks include:

• Attention K-Mart Shoppers
• Synthwave

Poetry

It was common for lost souls to eventually scribble out poems and thoughts onto the walls using whatever material they had on them, sometimes including their own blood. A sample of poems scrapped from the Backhall walls include:

"1000 Rooms 4000 Walls 2000 doors 10,000 Halls Did I get them all?"	"Franny Cranks served Us our last meal. I'll never understand How to get back To room 420 And have another"	"Is it counting up till dawn? Or counting down till we're all gone? The strength to proceed, I don't got it Won't reach the dominant or tonic"
"I saw the most peculiar clock It counted ways I'd never thought It didn't just count seconds up But minutes left and hours rough And thus when I would count the time I would rely on chalking line Imposing from the floor below Just tell me clock now where to go"	"Glassbreaker Glassbreaker break me some glass Bond me for life To your eternal mass. Let me seek justice and punish the foes Who crawl in the halls alone."	"Since I don't know the way, I'm beginning to think I've been lead astray. I could spend all the rest of my days Escaping from a Maze."
