Sino-Nordic Pact

All Nordic countries are Scandinavian territory. They form the Kingdom of Scandinavia.

Western Russia (West of Kazakhstan, roughly), Ukraine, Belarus, Lithuania, Latvia and Estonia are Sinaese. They form New Sinae, which is governed by the Sinaese Federation(?).

Plothooks for New China: Tension between the Chinese and the local Russian population. Undead hordes. Buddhist missions. Missions to China as a big thing. Plenty of wilderness is also common there, combined with the zombies it makes for very bleak missions. Chinatown, fireworks and some cultural flavour will help. The Arc of Life is also a thing (see below). Also monsters from China are emigrating as well (Chinese Dragons, etc) and maybe other Asian nations attack from the East/South eventually?

Plothooks
Gods shenanigans. Also conflict with China. Sailing. Sea monsters. Unique creatures/societies from Mythology and doors to other worlds (like in Thor https://en.wikipedia.org/wiki/Norse_cosmology#Nine_Worlds). Lots of trolls/frost giants (Jötunn). A portal to China (Álfheimr (https://en.wikipedia.org/wiki/%C3%81lfheimr)) due to that being one of the Nine worlds could be how the Chinese originally got there? Certainly the Norse have always been aware of the Elves and China, some explorers have been there. Also the road to the Underdark! Norse mythology has Dark Elves!!! Witch trials(?).
