Folding Halls of Halas

is an extra-dimensional manor with about one hundred interconnected rooms, created by the archmage Halas in the Age of Arcanum. It is accessed via the Heirloom Sphere. A blue dragon guards parts of the manor in exchange for food. Other dangerous creatures into his manor as well.

The time inside of the halls is different than on the Material Plane, one day passes in the Material Plane for each hour spent in the Halls, although the various chambers may not be consistent.

Interior
The rooms in the dungeon are connected by hallways with an extraplanar essence to it.

Tapestry Entrance
This entrance is a stone room with four pillars. Twelve feet off the ground are four different colored banners (red, green, blue, and black) hanging on the walls parallel to each other. All the banners have the symbol of Halas in gold in the center.


 * The blue banner hides a stone dragon statue with sapphires for eyes. hen the banner is moved the statue emits a blue and electrical energy.
 * The green banner hides a statue of a sickly, bloated humanoid creature. When the banner is moved a green poisonous gas fills the chamber.
 * The red banner hides a red wooden door with the symbol of Halas painted on it. When the lock is picked, a magical flame burst out and the door can be opened. This door leads to the study.
 * The black banner presumably hides a statue linked to the "Wailing Creature".

Diamond Entrance
The entrance is a diamond-shaped chamber with on the ceiling there is a relief sculpture of a curving tower encircling a humanoid figure without a face. There are two archways: one silver and one gold. The gold arch smells earth and greenery and leads to the Garden.

The Study
The study is a seventy foot tall chamber full of books and a few cabinets. The cabinets are protected, making it animated when touched. One wall has a forty foot tall, fifty foot wide stained glass window up one level of ladders. Above one of the desks is a twelve foot tall, six foot wide picture of a Halas sitting in a chair. In the desk is a jar of glass beads, a large vial of ink, and a small porcelain doll with oddly realistic hair.

The stained glass window has a layout of the planes, the Ethereal Plane, Astral Plane, and four Elemental Plane are all pictured. There is no Divine Gate pictured in the window, indicating this design may be over 800 years old. It has a small, red circle in the Astral Plane that is not tethered to anything. Touching the red circle, someone can be transported to the Dragon Guard Exit.

Dragon Guard Exit
This chamber is an arrow-shaped chamber with dark hallways. The chamber is filled with gold, gems, bone fragments, a pedestal and in the middle a circular stone raised platform. The platform functions as the entrance to the chamber from the study. There is a pedestal in shadow with an orb set onto it.

At the end of both hallways is a green-blue crystal set in alcove that absorbs cold energy. Across the floor are grooves that feeds the energy from the crystals to the pedestal.

The Garden
The Garden is a lush tropical jungle with a waterfall pouring down a massive mountainside cliff cascading into a small murky pool. There are multiple creatures living In the garden: soft little motes of dancing Scribe Mites that are attracted towards magic for food, frog-men, and a giant frog-like creature. In this room there are multiple pathways to other rooms: In the pool to The Nest, in a tree to the Crystal Mines, On top of the cliff to the Tower Machine, and behind the waterfall, there is a slight opening where a red-painted doorway stands that leads to the study.

Tower Machine
Standing on a stone ledge is an immense curving clockwork tower in the middle of an endless expanse of nothingness. A flash of purple lightning illuminates the area.

The Mighty Nein and Twiggy arrive in the Tapestry Entrance and realized Yasha was not with them. There were two mummified corpses Caduceus uncovered that they were killed by "the wailing creature" that came from behind the black banner. They pulled the blue and green banner aside avoiding the green gas in the Leomund's Tiny Hut. They pulled aside the red banner revealing the door. They successfully picked the lock and avoided the flame. They tried the door handle again and it opened. Caleb sent Frumpkin into the hallway and the party followed Frumpkin and they arrived in the Study.

Arriving in The Study, the party inspected the picture above one of the desks and the stained glass window and noticed the red circle. Fjord touched it and the window loudly shattered, sucking him into a black void and vanished. The window reformed and closed behind him. While Beau and Jester ran up to the window to follow Fjord and noticed a fingerprint on the red dot. Nott and Twiggy checked the Study for information. They got attacked by a cabinet. Nott finish it off with one of her “Explosive” arrows. After the win they continued the search, and found;
 * A jar of glass beads, a large vial of ink, a small porcelain doll with oddly realistic hair,
 * A large red leather-bound book with sapphires embedded in the cover,
 * A book titled: Public Debate Records: Forum of Ziedel,
 * A book with a burn mark on the front where a title should be.

Before anyone could investigate further, Beau touched the red circle and disappeared with Jester. Twiggy and Caduceus followed them, leaving Caleb and Nott alone in the library. Nott and Caleb continue to look for books. They got two more books before they joined the others. Arriving at the exit Fjord found himself before a young blue dragon. He negotiates with the dragon but was not interested. When Beau and Jester came in, Beau summoned a fire elemental smashed her red elemental gem to attack the dragon. That’s when Caduceus and Twiggy fell from the ceiling.

Fjord and Beau found the two green-blue crystal down the hallways. Beau noticed the groove running on the floor. When Jester cast Hellish Rebuke, the cold energy shot to one of the crystals. Energy from the crystal ran through the groove in the floor towards the center room pedestal. Fjord cast Armor of Agathys on himself to smash his head against the so it could absorb the cold energy in the same way. Energy running through two grooves in the floor led to another orb in the pedestal. Beau ran to pedestal orb, reached out, and vanished. The fight continued and when Caleb and Nott finally dropped into the chaos, they saw angry dragon on fire, the fire elemental, and a four foot tall Halas (Twiggy's in Disguise Self spell). One after the other, Caduceus, Fjord, Caleb, Nott and Jester ran to the sphere, and vanished leaving Twiggy alone. Twiggy, popped out of hiding and shot the dragon right in the heart killing the dragon. Twiggy ran to the sphere, touched it, and vanished.

Entering The Folding Halls of Halas again the Mighty Nein find themselves in the diamond entrance. Beau smells earth and greenery from the gold arch and they decide to go through the gold arch towards the garden.

Upon entering the garden the party Beau recognizes the Scribe Mites, and found a slight opening behind the waterfall. They begin to hear frogs croaking. Using her Ring of Water Walking Nott dashes across the pool toward the waterfall, and is swallowed by the a giant frog-like creature rising from the depths of the pool. Caleb began the attack by casting Fireball, hitting the frog creature and several frog-man. His use of magic also draws the scribe mites to lightning attack him. In the fight Caduceus also got swallowed and Caleb to cast his new spell, Widogast's Web of Fire,. Jester finishes the frog creature scaring the frog-man away. The party discovers all the doorways in this room. While they search, Caleb sends Frumpkin through to the Study and discovers that the books it once held were gone.

The party rest on the top of the cliff, and uses the mirror to contact Allura Vysoren. She warns them that if there's a Golem Workshop within the Folding Halls, there are also probably roaming golems. They hear heavy approaching footsteps as a metal golem (resembling the figure on the ceiling in the first room), and quickly dive through the archway. They find themselves standing in the Tower Machine.
