According to Hunter Quentin, Gogmurch was somewhere inside the underground tunnels of the House Soak in the city of Bogmoor.
As Ned ascends from the mechanical lift, he oversees the Sudden Plate city below him. It was rather nostalgic with the lights sparkling in the distance as though he was back at the cities of Earth. Instead of the sound of vehicles, there was the soothing sound of the waterfalls beside the lift. Carriage wheels rolling against the cobblestone road of the city, and the crowded intersection of each building. Instead of people drinking beers with other co-workers, there were hunters looking for a party, merchants selling their products along with hunters selling their loot.
