one of the many things I'm excited about re gw3 is the nature of it being a prequel and all the free extra depth that comes from that.
you're a vaelwarden, a protector of the people and spirits of orr. all the good your vaelwarden does, all the happy things that happen to them are going to be underpinned by these bittersweet, tragic feelings of "but in the end it was all for nothing". and maybe some people dont like that, but I think getting to see orr have it's fleeting time on tyria is like. awesome. maybe the vaelwarden will love orr and put their entire soul into caring for it all. and one day it'll all come crashing down and sink to the bottom of the ocean.
I could go on about how that the temporary nature of all that good ultimately not meaning much is very. life. that's life. and it still matters even if it all vanished. it matters because it vanished. but then its also what happens in gw2 that gives it so much meaning to me.
sure, everything your vaelwarden achieves is temporary, maybe nothing much in the grand scheme of things. but like 1300+ years into the future after everything you worked for was destroyed, someone who has never known you and your story will come along and be so dedicated to reviving the land that you loved and making it something new and cared for once again. some guy, part of a race you could have never conceived of, will rally the collective effort of the world for the sake of removing the rot and filth from this ruin that was so long forgotten. that legacy will encourage a whole new generation of adventurous spirits to flock to this place because they see hope and potential in what it could become with some care. they carry on your work in a new way.
the will of determined people echoing throughout the centuries. an unseen line between then and now.
thats just so awesome to me.
