The book of Truth was foretold in the Bible – see below:
Daniel Ch 10 (NAB Bible)
1 In the third year of Cyrus king of Persia, a revelation was made to Daniel known as Belteshazzar, a true revelation of a great conflict. He grasped the meaning of the revelation; what it meant was disclosed to him in a vision.
2 At that time, I, Daniel, was doing a three-week penance;
3 I ate no agreeable food, touched no meat or wine, and did not anoint myself, until these three weeks were over.
4 On the twenty-fourth day of the first month, as I stood on the bank of that great river, the Tigris,
5 I raised my eyes to look about me, and this is what I saw: A man dressed in linen, with a belt of pure gold round his waist:
6 his body was like beryl, his face looked like lightning, his eyes were like fiery torches, his arms and his face had the gleam of burnished bronze, the sound of his voice was like the roar of a multitude.
7 I, Daniel, alone saw the apparition; the men who were with me did not see the vision, but so great a trembling overtook them that they fled to hide.
8 I was left alone, gazing on this great vision; I was powerless, my appearance was changed and contorted; my strength deserted me.
9 I heard a voice speaking, and at the sound of the voice I fell fainting, face downwards on the ground.
10 I felt a hand touching me, setting my knees and my hands trembling.
11 He said, ‘Daniel, you are a man specially chosen; understand the words that I am about to say; stand up; I have been sent to you now.’ He said this, and I stood up trembling.
12 He then said, ‘Daniel, do not be afraid: from that first day when, the better to understand, you resolved to mortify yourself before God, your words have been heard; and your words are the reason why I have come.
13 The Prince of the kingdom of Persia has been resisting me for twenty-one days, but Michael, one of the Chief Princes, came to my assistance. I have left him confronting the kings of Persia
14 and have come to tell you what will happen to your people in the final days. For here is a new vision about those days.’
15 When he had said these things to me, I prostrated myself on the ground, without saying a word;
16 then someone looking like a man touched my lips. I opened my mouth to speak, and I said to the person standing in front of me, ‘My lord, anguish overcomes me at this vision, and my strength deserts me.
17 How can your servant speak to my lord now that I have no strength left and my breath fails me?’
18 Once again, the person like a man touched me; he gave me strength.
19 ‘Do not be afraid,’ he said, ‘you are a man specially chosen; peace be with you; play the man, be strong!’ And as he spoke to me I felt strong again and said, ‘Let my lord speak, you have given me strength.’
20 He then said, ‘Do you know why I have come to you?
21 It is to tell you what is written in the Book of Truth. I must go back to fight the Prince of Persia; when I have overcome him, the Prince of Javan will come next. In all this, there is no one to lend me support except Michael your Prince, (Ch 11) 1 on whom I rely to give me support and to reinforce me.

And the conclusion of the story in Daniel Chapter 12 (below)
1 ‘At that time Michael will arise — the great Prince, defender of your people. That will be a time of great distress, unparalleled since nations first came into existence. When that time comes, your own people will be spared — all those whose names are found written in the Book.
2 ‘Of those who are sleeping in the Land of Dust, many will awaken, some to everlasting life, some to shame and everlasting disgrace.
3 Those who are wise will shine as brightly as the expanse of the heavens, and those who have instructed many in uprightness, as bright as stars for all eternity.
4 ‘But you, Daniel, must keep these words secret and keep the book sealed until the time of the End. Many will roam about, this way and that, and wickedness will continue to increase.’
5 I, Daniel, then looked and saw two other people standing, one on the near bank of the river, the other on the far.
6 One of them said to the man dressed in linen who was standing further up the stream, ‘How long until these wonders take place?’
7 I heard the man speak who was dressed in linen, standing further up the stream: he raised his right hand and his left to heaven and swore by him who lives for ever, ‘A time and two times, and half a time; and all these things will come true, once the crushing of the holy people’s power is over.’
8 I listened but did not understand. I then said, ‘My lord, what is to be the outcome?’
9 ‘Go, Daniel,’ he said. ‘These words are to remain secret and sealed until the time of the End.
10 Many will be cleansed, made white and purged; the wicked will persist in doing wrong; the wicked will never understand; those who are wise will understand.
11 From the moment that the perpetual sacrifice is abolished and the appalling abomination set up: a thousand two hundred and ninety days.
12 Blessed is he who perseveres and attains a thousand three hundred and thirty-five days.
13 But you, go away and rest; and you will rise for your reward at the end of time.’
