Orr
Guild Wars 3's setting: the human kingdom of Orr, standing, centuries before the Cataclysm that drowned it.
Orr is the kingdom Guild Wars 3 is set in. Players of the earlier games know it as ruins — in Guild Wars it sinks beneath the sea during the Cataclysm, and in Guild Wars 2 it rises again as the risen land of Zhaitan. Guild Wars 3 goes back to it whole.
That choice is what makes the setting legible to newcomers and loaded for veterans at the same time: the audience already knows how this place ends.
