Since you know about the walkthrough, you should be able to CTRL+F for "royal library" to find this, but here is the current entry:
One of the two “advanced libraries” in the game. There are a few ways to gain access to it, but they are all tied to the Emperor (and thus, being a noble is prerequisite):
- Join his harem (see above);
- Have a relationship score of 5 or higher with the Emperor;
- Complete the quest “The Weak Link”;
This means that the library is only available from chapter 3 at the earliest.
As for the first temple, perhaps things got more complex over time, so I didn't account for certain possibilities. Are you using the schedule? If you never leave your house through the door, this scene won't trigger, but otherwise you should have a visit from a friend of your uncle after the first day. He tells you to go talk to him at the mage guild, and he will then guide you to the first temple (this visit gives you the quest "First Dig" in the questlog).
If this was the case, I can always modify the schedule to trigger the scene as well.
