Spellbooks Version: Portals

"Of course, if there is a Multiverse surrounding us, then there has to be a way to jump from one universe to another. Portals, my friend, are the solution. They come in a spectrum that ranges from willingly summoned to accidentally stumbled into. Portals are more than magic; they can also be just a wound in your own reality, which leads to another universe bleeding into your own. This book contains a collection of information about this, but I urge you to handle this wisdom with care. You won't know what you will fall into otherwise."
