Escaping Guild Hall
Do you mean you climbed onto the top of the cavern Guilded Hollow is in? Or did you get between the cliffs at the edge of the normally explorable part of the map and the real edge?
If it’s the first one there’s a lot to see, including some huge jungle trees, some desert terrain and lots of good places for guilds to build jumping puzzles.
In the second case I’ve not managed to do it myself but I imagine it’s much the same as every other map – some trippy scenery where the ground is perfectly flat and then just stops and you can see underneath it, the weird effect where you hit the edge of the skybox and your character jerks along instead of walking and maybe some weird points where you can get stuck, but nothing you can really do.
“Life’s a journey, not a destination.”
I got to the Jungle part and explored awhile but abandoned it to go to WvW. Took along time to build a super-cloud staircase. I want to try the sse corner sometime, there appears to be an unopened area there.
