Short q to those more knowledgable on Pathfinder than me: is there a  chronicle/log/diary/magical e-book writer that is<br/><br/>a) cheap enough to be bought with starting wealth (up to 50gp)<br/>b) lightweight (I do not have STR 16 ^^)<br/>c) weather resistant (paper tends to dislike water)<br/>d) offering quite some space to write (like dozens/hundreds of pages)<br/><br/>?
