Adding a Codex: go for realism or gameplay?

One feature that has been asked for many times in the past was a place where you'll be able to track the amount of children sired, as well as find information of all deities, fiefdoms, buildings, Karder's stats etc. So in version 0.13 we'll add Codex containing all the information specified above (let me know if you'd want anything not specified!)

But I'm wondering where to put this Codex. From a more "realistic" approach, putting it in the palace would be the coolest. You go to the palace and you click a link, like going to the Dungeons or the palace yard. However, we could also make it always available from the left menu, so if you're in a middle of a quest and wish to remember who Chiroz is or if you're in the world map and would like to learn how buildings exactly work, it would be easier to have that info exactly where you are. 

 So what do you think? Realism to Quality of Life? Have the codex accessible only from the palace or from everywhere?

1. The codex should be available only from the Palace
2. The codex should be available from anywhere
3. Both are good
