Guild Wars 2

Will there be lores in the future for the legendary weapons like new mysteries dungeons connected to them or even events or will be there a puzzle with clues, secret messages representing a piece of lore of some legendary weapons like the risen high wizard will he have a lore of how he even got the eternity in his way or his true identity

i doubt it.

Message Body length must at least be 15.

One can hope. Seeing as most ascended stuff has flavor text (laurel stuff, at least), it would be nice to see the legendaries get a bit of flavor text. Supposedly, there are clues around the world that hint at what you need to make a legendary (or there was supposed to be a long time ago? idk)
Anyway, as Bruno said, doubtful, but it would be cool
