Begin preparing the spell; the chanting and focus will take five hours. Upon the final minute, choose yourself and up to nine other creatures around you, touching each on the forehead. An unwilling creature can make a Constitution saving throw, and if it succeeds, it isn't affected by this spell. As the spell casting ends, a blue fire falls from heaven and engulfs each creature chosen by the caster. All creatures and their belongings are engulfed in blue flames and disintegrated. No trace of any is left, but for memories by others.

20,000 days pass. The creatures are lost to time and become merely stories. 50 years go by, and a generation disappears. The stories become legends.

The spell now ends, with blue flames bursting forth on a random coastal beach. Each creature is reborn, some 50 years later, and awakens from their nothingness slumber. However, the spell has also morphed each into something younger, something different, something new. It takes a short amount of time for each to come to realize what changes have happened.

Each player creature changes dramatically. They are turned into a new race of creature, randomly. Next, each creature comes to realize that they are a new type of class from before and are at level 5. New memories seem to have been created that allow for these changes to take place. The classes may be random or chosen, based on a creature's deep desire from long ago. Targets' game statistics and hit points are adjusted to fit the new race, class, and level of these new forms. Characters retain memories of the time before, but can no longer cast certain spells or have proficiencies if their new forms do not allow for them. 

Pets and other creatures are also turned into new creatures, at random. Their affections stay the same, so if they were a pet or if they were an enemy, they will stay as such, respectively.

Non-magical gear stays the same, though pieces worn morph to fit the new creatures.

Magical gear changes entirely. Each magical item changes into another magical item at complete random. If it is a worn magical item, it also changes in order to fit the initial wearer's new form.

The GM will help each player adjust the new characters and equipment. This spell is permanent and cannot be undone. The characters now can grow and develop the new forms, though.

Time has forgotten these creatures, but now they have new opportunities to discover, with new stories to create.
