This quest starts by examining any of the banners that hang in a ring surrounding the room with the green dragon Palace Adjutant Drakknair. This is the dragon room above, then along and up a lift from the room with the Advisor in which you completed the previous quest.
DO NOT CLEAR THE ROOM BEFORE YOU CLICK THE BANNER AND BOOK.
To learn more about these banners inspect a large tome (named Banners, Banners, Banners) on level 6 ( -133, 132, 13 ) /waypoint -132.64, 131.99, 12.57 on the floor on the west side of the room. Kill as few mobs as possible as you will need updates from some of them. If the dragon Palace Adjutant Drakknair is up, it will be difficult but not impossible to get close to the tome to examine it without aggroing.
Collect six gems from the same room. Gems I, II, III, IV and VI can all be found in chests dropped by the animated barricades. Gem V is dropped by Palace Adjutant Drakknair. All the gems are LORE and NO-TRADE and each person in the group must loot all six to update their quest.
Note : To spawn the Dragon you need to clear the entire room. After killing the dragon and his Dreadknight guards, the room respawns after 25 minutes.
After collecting the gems you need to place them in the banners in a specific order. If you are on the elevator coming up facing all the banners then the order starting on left going clockwise is (1-2-3-6-5-4) I-II-III-VI-V-IV .
NOTE: Make absolutely sure you do it in right order or you lose that gem and need to get it again. If you are completing the quest as a group, only one person should attempt each update at a time, so that any mistakes will only need one gem as a replacement. As you place the gems they will vanish and you will get an update.
Click on three large books (on the floor) ( -136, 131, -15 ) /waypoint -136, 131, -15in the same room and receive a key. Inspect the key in your inventory.
After receiving the key go down the elevator and in the NE corner room you will find a chest ( -185, 111, -31 ) /waypoint -185, 111, -31. You will need to kill as little as possible to get to the chest, due to the next step. Click on it and you receive an item (egg) you need to examine.
You then have to kill a Bloodscale Counselor which are located in the rooms in this area. Keep killing them till you get your update. (High Priests seem to be placeholders). After you obtain this update from the counselors, inspect the egg in your inventory again.
Head to the Oratory of Naar Y'ora, ( 0, 111, 0 ) /waypoint 0, 111, 0 the room in the tower below where the Great Aviary is. Should see three elevators that go up to where the Enmity is located. You will see a room with three elevators in the middle of the room is a circle. This circle contains a Skylord. Standing in this circle will update the quest. However, you need to kill the Skylord for the next step, so be careful while updating. Best bet is to kill him where he stands and after you get the update for the circle.
The title of this quest is likely an homage to the 1947 war movie Twelve O'Clock High about crews of the United States Army's Eighth Air Force who flew daylight bombing missions against Nazi Germany and occupied France during the early days of American involvement in World War II.
