Essence of theAkashic Grimoire

The book can at a great cost of any kind of supernatural energy send you to different worlds and if drawing from your own reserves at a low level of enhancement would leave you near empty of whatever energy you used. Once you have been to a world the energy cost to travel to it is half as much. The method of travel defaults to a portal that lasts long enough for you and any others you want to travel with you to step through it though you may decide to use something different like teleportation. If you wish to transport yourself while in a vehicle, even something as large as a spaceship you may take the entire vehicle with you including any passengers onboard. You can choose the specific world you go to, even going to alternate timelines, "fanfic" versions of that world, or let the book fling you to a random world. The book will transport you to a relatively safe and out of the way location so you don't have to worry about getting jumped when you come out the other side. Once you have been to a world you can decide where you will appear when you visit said world again.

The book is pre-loaded with enough 'generic' supernatural energy specifically to send you to another world once and get back home before requiring you to provide more energy from there on. Built in safeties prevent you from using this store of generic supernatural energy for any other purpose. Should you use it all and strand yourself on a world that lacks any sort of supernatural energy and have not undergone any enhancement to let you generate your own supernatural energy the book will still generate a small trickle of the same generic supernatural energy. Enough that you could after waiting a two weeks to a month travel to a previous world or a new world respectively.
