Mordremoth is trying to retrieve and assemble the bloodstones.
The drawing in Scarlet’s room/design in the vision looks so familiar to the design on the floor of the Bloodstone Fen/door of the bloodstone caves. That means (if you believe bloodstones are at work here), you can infer that the Master of Peace had a bloodstone in his possession and Aerin (under Mordy influence) was trying to seize it. The MoP, of course, said that what he had was an item of great power. AND he was headed in, what appears to be, the direction of Bloodstone Fen deep within the Maguuma Jungle.
The crystals in the vision, I, and a few others, believe to be a depiction of bloodstones themselves. And you could see rising towers, which looked an awful lot like the Mursaat Towers (with, and this is a stretch, the Ether Seal glowing gold in the middle of the vision). The Mursaat (I’ve forgotten a lot, so correct me if I’m wrong) originally used the bloodstones to keep Abaddon sealed away out of fear that they would be wiped out. If they have the idea that Mordremoth will also be a danger to themselves, they’d want the bloodstones for themselves (as they did back in GW1).
Of course, you need the blood of the true ruler of Kryta to unlock the magic within the bloodstones. And Queen Jennah has that blood running through her. Added to that, we’ve been told of a powerful artefact that can reveal the true ruler’s face. I can see this going three ways. Either the queen will get cheap guild wars 2 gold and the player will use this artefact to find her. Or the queen will die, and the enemies will use the artefact to locate the next ruler to unlock the power. Or, the queen will die while unlocking the bloodstone power (just as it was implied that King Doric died after his blood was sealed to the bloodstones).
Basically the queen’s in trouble. Countess Anise will have a lot of saving to do. Which brings me to the next theory, which a few have also thought of. Anise is Livia from GW1. After getting the Sceptre of Orr, she would have had enough time to learn Mesmer magic (not impossible, in GW1 I was a necro/mesmer), and would have had enough time to fit herself into the Queen’s land. But that’s a completely different story which might be tackled after the story moves towards the Door of Komalie and Soul Batteries and stuff, probably in LS Season 3 (or late Season 2).
