So I think it’s time we had a dedicated thread to this plot.
The first mention of a threat to a leader, if I recall correctly, was in episode one during the Cornered instance.
After defeating Aerin we find a note scrap on his body that reads:
…leader will die. The rest will fall in line. We will not fail."
Early guesses pointed at the Master of Peace (the person Aerin was specifically targeting at the time) but information since suggests it’s not that simple. Upon revealing that the vines in Prosperity are the work of Mordremoth, Kasmeer seems to suggest it might be Trahearne.
Kasmeer: Aerin said a Tyrian leader would die. This makes me think someone—or something—was pulling his strings. That scares me the most about him.
Player: Trouble is, we have no idea who he meant.
Kasmeer: It could be anyone, though the biggest threat to Mordremoth is probably Trahearne. I hate the thought that Queen Jennah could be in danger too.
I believe she only mentions Jennah because Kasmeer is a human noble that loves her Queen (she expressed concern for Jennah last year after Scarlet attacked). Killing Trahearne makes a lot of sense because he is the only one on Tyria with a proven track record for taking down an Elder Dragon.
Adding fuel to the “Queen Jennah is the target” theory we have the Priory artifact from The Concordia Incident.
Magister Lindsay: Thank goodness you found us. I was afraid we’d be trapped here. How did you know to look for us?
Player: We heard there was trouble at Concordia and came immediately.
Magister Lindsay: How bad are things over there? Have the items in the fort been compromised?
Player: I’m afraid so. The Vigil have reatreated to Goldenlight Hallow lab.
Magister Lindsay: What are we going to do now? Our caravans were carrying magical artifacts out here for safekeeping. The Krytan royal locket is among them.
Player: The Krytan royal locket?
Magister Lindsay: It’s a magical locket. It’s said to always have the image of the current heir to the throne of Kryta displayed inside it. It’s quite beautiful.
Player: It sounds powerful.
Magister Lindsay: Very powerful. And coveted. We move it from fort to fort on an irregular schedule. I probably shouldn’t even be telling you about it, but…you’re you.
Player: My lips are sealed.
Take note the Concordia’s leader claims the vines first appeared when the Priory caravan arrived.
Tactician Art: Well, a few small vines popped up after the Priory caravan arrived, but we didn’t pay those any mind. Er, until they grew.
Personally I think that’s simply to demonstrate that Mordremoth is drawn to powerful magical artifacts (I believe there was a Priory Personal Story plot that deals with the same thing when Zhaitan’s minions go after Priory HQ for their artifacts – Mordremoth hit Fort Salma because of the krait obelisk shards). At the end of the instance Lindsay mentions the artifacts are drained of their magic but the locket is only weakened. Also note that while there are multiple artifacts, the Krytan Royal locket is the only one specifically described. Like Mai Trinn was the only named crowd member in Dragon Bash (suggesting she was the culprit from the get go) this suggests that the locket will be an important detail in the future. Some people suggest the locket could be used to track down Jennah’s heir if Mordremoth kills her (she is the leader Aerin refers to) but I personally think it is related to the true heir to Ascalon and the Foefire curse (tweak it so find the Ascalon heir instead of the Krytan heir).
