Guild Wars 2

ok so ive been threw the puzzle, but it keeps seeming like there’s stuff going up and I can’t figure out how to go up. I watched some youtubes of this puzzle and most all of them mention the same thing. So, I’m trying to figure out if anyone has figured this out yet? Is there a way to go up?

I was wondering if there is a way to redo, as in get points back and reapply them in my slot skills? First time playing game and I did not pick good

I got one and now trying to figure out who to take it to, cause it says: This tablet contains a partial history of people and events in anicent Demetra. Take it to the Durmand Priory Explorer to gain renown in the area. So I’m here at the Durmand Priory Waypoint and none of the Priory Explorers let me talk with them. What do I do and is there a certain Explorer I’m suppose to go to and if so where? Thank you for your help, I have googled and nothing.
