Guild Wars 2

I just finished the Living story and I wanted to confirm that I understood what I saw. It looks like The Pact warriors from Vigil, Priory, and Whispers got corrupted while flying over and sabotaged the ship. I don’t know why, but I also thought an option that somehow Sylvari already in the jungle got on the ships, like going up to the ships along with the vines. Since the Sylvari personal story has Malyk, which came from this area. I thought that as possibility has well.

Can someone help me confirm? Thank you kindly.

It’s pretty well established both by common consensus and by dev comments in interviews that the sylvari we see fighting on the ships are Pact sylvari helpless against Mordremoth’s influence. If you look at their armor, it’s the stuff we see in our part of Tyria, not some new jungle gear.
