La carte Kharasha Foothills prend place sur Mongseng, qui était le premier jet d'un Plan qui fut ensuite étoffé puis renommé Tarkir.

Source (World at War - "The card was Kharasha Foothills and the plane was called Mongseng. [...] In the end, the decision was made not to call it Mongseng (something similar had happened during Theros design with the Planechase card Lethe Lake from the plane of Arkhos) but other than a name change, the basic concept of the plane stayed constant.")
