Vesona

Vesona is an artificial plane created by an oldwalker, where dreams and reality blur together.

More details
Vesona was created by an unknown planeswalker hundreds of years ago to act as a place to be alone with their thoughts. However, they rapidly found this to be a boring and tedious experience, so they began to populate the world with people, each with their own lives, internal narratives, and personalities. These people, much like the plane itself, were not real; they were illusions substantiated by the planeswalker's power and an artifact they held called The Looking Glass. With every passing day, these illusions became more and more believable, more and more real, until the fiction was almost indistinguishable from reality.

Eventually, the planeswalker left, and never returned, dying on another plane across the multiverse. But Vesona stayed, perpetually kept real by The Looking Glass. And then the Mending happened, and the artifact broke cleanly in half, all of its power dissipating. And yet the plane stayed. The nature of illusions meant that since the plane was full of people, and all of the people there believed that the Looking Glass was still present and still able to keep the plane together, the illusion was able to hold. As long as the few people who knew about the destruction of the artifact kept it secret.

But the doubt that crept in from the people in the know started to eat at the plane. Along the edges of the plane, reality started to crack and blur. In those areas, idle fantasies and dreams began to take hold, and threatened the stability of the plane further. The government created an organization of Dreamcharters that they tasked with patrolling the edges of the city and pushing reality further and further, desperately trying to cling to stability.
