According to several indicators ingame this map is located in Maguuma which is completelywrong. It’s actally somewhere on the area of the historical Ice Caves of Sorrow in the Southern Shiverpeaks or “today’s” Steamspur Mountains (which is correct according to the API’s floordata).
Same goes for the Bloodtide Coast, Sparkfly Fen and Mount Maelstrom. While Sparkfly Fen was treated as Tarnished Coast (not Maguuma) in GW1, it seems it’s something like “Steamspur Foothills” today along with Bloodtide Coast (which could be also Kryta). Mount Maelstrom is definately Shiverpeaks/Steamspur Mountains.
Anyway, we’re agreed that Maguuma is on the other side of the map, right?
