A Rip of Realms

The world-building feels so expansive and detailed—I'm curious whether the author mapped out all the realms from the start or let them evolve naturally.

The romance scenes felt really charged, but I sometimes wished for more focus on the adventure. How did others feel about the balance between romance and plot?

The powers felt unique but also believable within the world. I'm wondering what process was used to craft these abilities and their rules.
