Stasis bubble

Stasis bubbles are magical phenomena found in the ruins of Aeor.

Description
Stasis bubbles are spheres of translucent blue force, ranging in size from fifteen to twenty feet across. Within the stasis bubble, time appears to be at a stand-still, as many bubbles contain citizens of Aeor frozen at the moment of the bubble's creation. The bubbles are completley invulnerable, and apparently unable to be dispelled.

History
The origin of stasis bubbles in unknown, though they were likely invented by the mages of Aeor, potentially through experimentation with dunamancy via the Primal Artifact.

The stasis bubbles found in Aeor's ruins appear to have been created at the moment of Aeor's destruction by the gods during the early years of The Calamity, as they often contain figures huddled in the streets or braced for impact as the city plumeted towards Eiselcross, wile others contain mages casting spells and warriors preparing for battle.

Explorers and treasure hunters that have found stasis bubbles have been unable to break or dispell them by any means, and it is unknown what would happen to those within the bubbles if they were to disappear. Some believe that people within might age rapidly, turn to dust, or go mad.

Campaign 2: The Mighty Nein
In their expedition to Eiselcross, the Mighty Nein encountered a few stasis bubbles. The first they found in the Aeorian ruin designated "A2", inside which were three Aeorian citizens. The second stasis bubble they found in the Praesidis Ward of Aeor's main crash site. The bubble was in the center of an amphitheater filled with mumified corpses and contained a mage named Brashaar.

Behind the scenes
Explorer's Guide to Wildemount leaves it up to DMs to decide how stasis bubbles can be broken, if at all. The book offers three suggestions for doing so:
 * An encoded ritual hidden within Aeor's ruins, which requires powdered a unicorn horn and a drided flumph tentacle for each bubble.
 * Destroying the crystal in Allowak's Sanctuary destroys all of the bubbles.
 * Attacking a bubble with an exalted Arm of the Betrayers destroys the bubble.
