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.

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.

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.

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."
