This thread is for gathering what we know about WoC and guessing what will happen.
Firstly the main wiki link:
So there are a few hints:Winds of Change is the third chapter of Guild Wars Beyond. Taking place in Cantha, Winds of Change will explain some events that happen after the end of Factions and, like previous chapters, will foreshadow events leading to the situation during Guild Wars 2. Completion of the Factions campaign will be the only requirement to begin Winds of Change.
The story of Hearts of the North has a connection to Winds of Change, most likely through Miku and her background story.
"Involves the plight of the tengu, the origins of the Ministry of Purity, and the isolation of the entire continent."
The amount of story content will be comparable to a small expansion.
WoC will be related to her story. Here is what we know about her.
Where the Embedded Arrowhead is
Keiran Thackeray: "Why are you so intent on finding Danthor?"
Miku: "I had finally found a home in Kryta. He...took that away"
Miku: "He branded my loved ones traitors. They were all I had left."http://wiki.guildwars.com/wiki/Majes...nce_of_Blades)At Danthor
Miku: "Danthor! Turn and face me!"
Danthor the Adament: "I don't have time for this. I must see his plan is set into motion."
Danthor the Adament: "You there. Handle this.."
-Danthor killed Miku's "family" in Kryta by branding her "family" Shining Blade supporters. This might somehow "support" the goal of a certain someone.At Danthor's Location
Miku: "There you are, Danthor! Accept your fate and die in peace, or die struggling in Futility!"
Danthor the Adamant: "Such tenacity. You still pursue me? It makes no difference, you know."
Danthor the Adamant: "His plans are already coming to fruition. What happens here will change nothing."
Miku: "Anything can change; all that's required is the will to do so. Let me show you mine!"
After Danthor dies
Miku: "At last...now the fallen can rest easier."
Keiran Thackeray: "It looks like some of the White Mantles escaped further into the Maguuma Jungle. What will you do now?"
Miku: "I need to continue. This time, for myself. The question is, Keiran, what will you do?"
Keiran Thackeray: "It's dangerous to keep on alone. I will accompany you."
Miku: "That's kind of you. I wonder, though. Maybe your kindness reveals that you rely on others too much."
Keiran Thackeray: "What do you mean?"
Miku: "Oh, I don't know. Is protecting me an excuse to keep on like this?"
Keiran Thackeray: "Let's keep on going; we don't want to lose them."
If we can find a list of all the people killed by the White Mantle we might have a better clue.
-Miku either have family back in Cantha, or she is an orphan. My guess is the latter.
-Donthor is serving someone, who wanted something done in Majesty's Rest. All we know of this "someone" is that he is male.
2) Plight of the Tengu
There is no info on this right now. But sounds like some kind of promise the Tengus made to somebody.
3) Ministry of Purity
Once again, no info on this whatsoever. Sounds like a ministry to "cleanse". Cleanse what is the question.
However, the timeline gives a hint of what this ministry will do.
Emperor Kisu ruled from 1058 AE to 1127AE (69 years). So he probably started the war before his son Usoku finished it.1127 AE: Emperor Usoku defeats the Kurzicks and the Luxons, unifies Cantha and begins purging non-humans and political enemies.
http://wiki.guildwars.com/wiki/Emperor_Kisu1058 AE: Kintah dies and is succeeded by his son Kisu, who becomes the 31st Canthan Emperor.
4) Isolation of the entire continentKisu's reign has lasted 69 years and he is one of only 3 emperors for which we know the length of tenure.
No surprise here, as that is destined to happen on 1219 AE with the awakening of Zhaitan. However since the current timeline is 1080 AE, my guess is there will be hints of the upcoming disaster. Or someone does something in 1080 AE that leads to the awakening Zhaitan.
So with everything together, here is my guess.
1) That "certain someone" is Emperor Kisu. He needed something from Kryta to defeat the Kurzicks and Luxons. He bribed Danthor and other White Mantle members to do the dirty work for him. Kisu might have secretly supported the White Mantle since the beginning.
2) Whatever it is, it won't be good for Krytan people. Miku's "family" found out and tried to stop it. They got killed instead.
3) Kisu will start the war against the Kurzicks and the Luxons as soon as he gets his "thing".
4) Tengus will "plight" to help Kurzicks and Luxons in their war against Cantha.
