Desecrate this Fire!

I don't want to do locs because 1. I didn't write them down and 2. they're easy to find once you know where to go and what zones have them and what zones don't. If it's not on one side of the village, it's on the other.

Okay, I think I have done all of the locations of alliance and horde bonfires for honoring and desecrating, respectively.

Here's the list - starting with Eastern Kingdoms:

Silvermoon City - H (for Allies)
Eversong Woods - Falconwing Square (North on the road from Tranquillen) - H

Now for Kalimdor:

So, that's my list, if I've missed any, please reply because that means I can go get more flowers. ^_^

(edit: thanks Daviexi - honored it yesterday and forgot it was there. Alas, no new flowers, yet. hehe
thanks Animated - I forgot to include Dustwallow Marsh when I was looking at the Kalimdor map & Chillwind camp flight point in WPL. Added the north road reference for Eversong Wood.
Fixed Dhazy - thanks. ^_^ I couldn't remember what that area was called (ran through in a hurry!) and only saw Fairbreeze Village lit up on my map.
Removed the "none that I saw" zones like Moonglade, Felwood, Un'goro etc. because it has been confirmed in other lists that there are, indeed, no bonfires there. :D )

Following is a list of all bonfire locations I was able to find in Alphabetic order after Zones, with coordinates and general areas for the few who don’t use coordinates.

I have found that bonfires are missing in Contested Territory Zones if the Alliance Flight Point and the Horde Flight Point are both at the same general location (close to each other) unless it is a goblin owned town.

I have also found that bonfires are missing for a faction in Contested Territory Zones if the current faction has no flight point in that zone.

I know not if there are any bonfires in Battleground Zones.

Honouring a bonfire from your own faction awards you 5 [Burning Blossom] and an amount of currency depending on your level. As level 70 I got 5 Gold Coins and 95 Silver Coins for each.

Desecrating a bonfire from your opposing faction awards you 10 [Burning Blossom] and an amount of currency depending on your level. As level 70 I got 11 Gold Coins and 99 Silver Coins for each.

You can not honour a bonfire in one of your own faction’s capitols.

You can not desecrate a bonfire in one of your opposing faction’s capitols, but you can get a [Flame of *Capitol Name*] which starts the quest [Stealing *City Name’s* Flame] which sends you back to one of your own faction’s Festival Talespinners for a reward of 25 [Burning Blossom] and a little something extra. You need to be level 50 or higher to start these quests.

Please comment any errors you find so that I may correct them.

To minimize your chance at getting ganked if you are not already flagged when desecrating a fire, you can start summoning your mount before clicking "Complete Quest". Then click it and you are ready to high-tail it out of there!
