Heirloom Sphere

The Heirloom Sphere, also known as the Archmage Bane and the "Happy Fun Ball of Tricks", is a magical item that conjures or stores objects and can teleport users to an extraplanar manor known as "The Folding Halls of Halas". It is currently being kept by Yussa Errenis in his mage tower in Nicodranas.

Description
The Heirloom Sphere seems to be a puzzle-like sphere mixing clockwork and magic; it appears to be brass and gold and polished. The structure is Rubik's Cube-esque, in that some parts have to be rotated to a certain position to allow other parts to rotate, and where there are seams between the rotating parts, a blue-green glow emanates. It has complicated versions of conjuration glyphs inscribed on it, along with impossibly small engraving across the metal. The item blocks spells attempting to Identify it or to scry on it.

Uses
The ball is a device of both clockwork and magic, mainly for conjuration. The found functions can conjure gold, jade, a temporary storage hole, and teleport everyone around the ball to Halas's manor. The amount of gold coins conjured within a short timespan is half of the previous one. It is unknown if this amount resets at dawn.

Beau theorized the sphere wasn't creating the gold, only conjuring it from the dragon's hoard.

The Folding Halls of Halas

 * &rarr; Main article: The Folding Halls of Halas.

The Folding Halls of Halas is an extra-dimensional manor with about one hundred interconnected rooms. A blue dragon guards parts of the manor in exchange for food. Other dangerous creatures reside there as well, including a froghemoth, bullywugs, and golems.

History
Halas supposedly placed several "pockets" around the world in order to tempt potential victims to the dragon's lair inside his manor.

Pre-Stream
Twiggy stole the Sphere from Sir Cadigan, who had imprisoned her. Based on Twiggy's description of the location, both Jester and the Cobalt Soul believe she got it from the Exalted Collection Auction House in Port Damali. She brought it with her as she stowed away on several ships, eventually hiding on the Squall-Eater when it docked at Darktow. She figured out how to use it to make coins appear.

Twiggy, Nott, and Caleb all investigated the, resulting in multiple conjurations. When the Ball produced a temporary portable hole, Beau, Nott, and Twiggy extracted Halas' winter equipment from inside. Twiggy eventually found the final setting, which teleported herself, Beauregard, Caduceus, Fjord, Frumpkin, Jester, Nott, and Caleb to Halas' manor.

Caleb Widogast examined the artifact the morning after the Mighty Nein had used it. All the rings and buttons they had used the previous day were in different places, making their conjurations from the previous day impossible to replicate.

The Mighty Nein gave the Happy Fun Ball of Tricks to Yussa Errenis. In exchange, Yussa allowed Caleb Widogast to memorize a teleportation sigil that will allow him to teleport back to Tidepeak once he learns the spell Teleportation Circle. The Mighty Nein may come back at any time and explore the Happy Fun Ball further if they like.

When Yussa Errenis disappeared while exploring the The Folding Halls of Halas, Caleb was able to manipulate the Sphere to transport the party into the Diamond Entrance of the Halls on a rescue mission.

the Mighty Nein wander the Heirloom Sphere into rooms of ever-growing danger in their search for Yussa and hoping to find a possible boon in their struggle against Obann.

The Mighty Nein find a dangerous item whose destruction could change the tide in their fight against the Angel of Irons.
