A fantasy novel being written by me.
Traveling through time and space is possible, even normal. Different star systems now regularly visit each other, but there are regulations, restrictions. There are some star systems that are dangerous to approach, while others are simply forbidden to enter their space. This Galaxy is very old, large, and home to many forms of life. But, while many life forms are inherently peaceful, there are more and more being affected by one thing that cannot be helped. Space is running out of space.
