The Keystone

Overview
The Keystone is an empowered gemstone recovered from the Switch. It has immense power over the fabric of space time and the space between worlds, and, if attuned to, can be used to teleport creatures and objects over vast physical distances, and even other planes of existence.

Because of the Switch's eagerness to recover the Keystone, it was theorized by Hwom Ching that the object could be an invaluable asset in the secret war against the Mad Mage. This hypothesis was proven true by the clone of Sarvoldis Ilifiel, who discovered the Keystone's connection to the Switch's Demiplane.

The Keystone itself is a polyhedral object measuring about nine inches in diameter, encapsulated in a golden-framed amulet. It is likely that the artifact was affixed to the amulet by High Priest Sarvoldis, and not the Switch.

Abilities
Using the magical energy stored within the Keystone, Daskrin has been able to teleport himself short distances, similarly to the Dimension Door spell. With proper focus, he has even been able to teleport groups of people across vast distances, including across leagues of ocean. He also discovered the Keystone's ability to shift the user between planes, accidentally launching himself across realms and into the Elemental Planes.
