I know that the UW (under world) was one of my favorite place in the Guild Wars, you get to fight a god Dhuum. now i have seen portals to the Under World but im wondering if arena net has hade a pan for UW. but my idea is this
Fulley explorable map
-Vistas
-way points
-points of intrust
-Major citys
now i remember that in the game the Underworld is as huge as the Mists it has a lot of difforent places and such why not allow for a hole new world inside the relm of the dead?
