I found this gem on Reddit earlier today that is an amazing graphic on Imgur showing the monster sets that can be obtained by the various undaunted pledge givers’ chests. Note the chests are not all in the same order at all locations as the graphic so check the chest label before using.
There was a lot of interest in the ESOTU pledge calendar so I published it to site. The link to the calendar now appears on the site menu and includes Normal and Veteran Pledges and the Alliance Vendor dates. Enjoy!
Sometimes it can be handy knowing when a particular dungeon will be the pledge. For example, If you are farming for a particular monster set item (eg. Engine Guardian, Mephala’s, etc.), you would have the best chance of finding groups running the dungeon of interest when it is the pledge of the day.
