Guild Wars 2

So I recently came back to the game after 2 years and pretty much missed all PvP Seasons so far. I haven’t fully grasped on how to unlock it but I have heard its quite timegated. There is still one PvP Season coming, right? Is there going to be another Legendary backpiece next year or is Ascension going to be available then?

Thanks for answers.

So I have about 700 bolts of Gossamer laying around for no purpose and I was wondering what would be the best way to turn it into gold?
