I am playing through Daggerfall for the first time, just wanting to get through the main quest. So far it have been quite straightforward, I know you need to be of certain level or of high enough reputation for some quest to be available and often you get a letter when a new part of the main quest is "unlocked". However I got stuck for a while since I got no new letter or clue about how to proceed in the main quest. So I looked it up and saw that one quest I need is given in the Direnni Tower: http://www.uesp.net/wiki/Daggerfall:Freeing_Medora

I am just wondering how you are supposed to know this? I know one npc mentioned a Direnni and her being in a tower on the Isle of Balfiera once after a quest. But this was not copied to the logbook as usual important information so how are you supposed to keep track of information like this given at one time in a conversation and know it is actually so important that you need to write it down or take a screenshot to be able to proceed? Or are you given this information somewhere else?
