"- please make it more obvious to the user exactly what they should be doing to advance the campaign. At the moment, it's a little more like wandering around until you trigger something. The "Chapter" books are nice, but they mostly tell a story rather than give you a specific objective."
I very much second this. Particularly as most players will be using the campaign as their introduction to the game, it really should do a lot more handholding. At the very least, there should be a log somewhere which stores the instructions you receive from people.
Anyway, I too am stuck near the Capitar Fortifications area, and I'm not sure if it's a bug or not.
SPOILERS FOLLOW (highlight text to read):
I found the survivor of the Kandrir assault (I think - but it's still giving me the false path message if I try to go West). And now it's telling me to go back to Kandrir to find the Tome of Dend'rir. Well, if I go back to what I think is Kandrir (the place where I got the survivor quest), nothing happens. If I push past the false path messages, I get to the Obsidian Wall, but I can't do anything about it. Am I wrong about what Kandrir is?
