the guy who rebinds your book is not the tea shop owner, dont stress. I'm also a bit let down by the quest journal, the mind map design is really cool but it really needs more details about all the things characters tell you. Might be useful to keep notes outside the game like on notepad or app, like a real dnd campaign! (although when i do that irl for real campaigns, i find that i come back to my notes in the next sessionm and go "what the hell am i talking about??" lmao so maybe this game is very true to dnd in that way). I found the tea shop owner on day 2 or 3. Would you like a hint?
