Barrier of Worlds

Rubbing the so-called powder of life between your hands, you scatter it among an area with a radius of up to 50 feet. This area has to be on your own home world in Braythe. If another Barrier of Worlds spell already exists in this place, your spell automatically fails. Once the spell is finished, a translucent, shimmering dome as high as the area is wide comes into existence. Any being originally from a different world-island of Braythe is prohibited from entering this barred zone. They cannot charm, frighten, or possess creatures within it, as long as the targets are also from your home world. Targets already under such an effect are released from it upon entering this zone. Beings that do not originate from a world-island of Braythe are not affected by the spell. This includes the Voidborn and the Beastborn. A person or creature that dispels the Barrier of Worlds, and who was born on a different world-island of Braythe, has to succeed on a Wisdom Saving Throw against a DC of 15. On a failure, they are banished to a random (but relatively safe) location in their home world.
