So the Kamen Rider website put out a full image of the "Forbidden Book"
#KamenRiderSaber
#Spoilers

Here is my rough translation.

Page 1:
The power to represent the world. Do not abuse the power, or use force. It is used to protect the human world and the development of the world and its boundaries. Development of the human world, that is for humans.

To protect the boundaries of the world. And, to prepare for the threat of those who seek to disturbe the world's boundaries. The power of one, even the minimum of power exceeds our expectations.

Its power goes beyond understanding. Here are some of the powers and possibilities. 

When 13 stories are connected with a sword, it leads to a gap between worlds."

Top of Page 2,
One part of the power, two parts of the power, three parts of the power, when the power is raised, you can reach beyond the realm of humans. It can be used as a starting point, but its destination cannot be understood by humans.

I saw the possibility of power, but I couldn't use it. The story is connected, but I haven't returned yet. Where the stories connected, you should not travel. There is nothing to see. Not even shadows.

There is nothing to feel. It is a world outside of existence. A world with no where to go. a world without night. I believe that this will lead to a world where people can not go, Beyond human knowledge. Therefore, from this point onward I will remain."

Bottom of page 2:
The Ancestors were trying to draw more power out of the Wonder Ride Books. Even if you can only use the power of one Wonder Ride Book from The Wonder World, the possibilities are still endless.

Through the Seiken, is the possibility of releasing further power. We will further strengthen the power of the Wonder Ride Book, together with the Seiken we aim for what we should be and the form of power.

The Wonder Ride Book changes the shape of the sword. That power, it is beyond infinite. Constantly changing shape and ability in response to the reader. Just like a story.

By putting Wonder Ride Book power in the Seiken, more power speaks. The power speaks out through the Seiken.

It is possible to unleash the whole power in one Seiken. However, I can't see the way ahead. Humans can only wield 2 or 3 powers in a single Seiken. Power Multiplication. Synergy.

Becoming the King of Power. Requires someone who can endure and draw out that power. And the sword that can handle the power. I still can't reach the answer in the darkness."
