If you destroy this journal you will have to get all of the pages back that it holds. They are not saved; however, if you have collected all pages, the journal can be put into one's bookcase to save a bank space. If the player has multiple Dominion Journals, they will not stack in the bank. The chance of receiving a journal page may be influenced by the amount of Dominion Factor accumulated. So, while you can normally expect more pages with more DF, it is possible for higher DF (e.g. 150k+) to result in no pages, or low DF (e.g. 30k) to result in several pages.
