@Dai Gurren Man There isn't really a designated "Asia" continent, though we have two blatant expies of Japan both located in the north-west (The orange one above the big purple blob is based off Shogunate Japan and the green island above that is based off Imperial Japan). This isn't really a proper Asia location though since those two are in proximity to Europeanesque nations like Ventium (Imperial Russia), Vincul (Essentially Not!European Union), the PRK (Soviet Union) and Yllendthyr (Elf British Empire).
Overall, I'd say Europe and Asia have been fused together into one continent and America and Africa have be fused into another continent (The "Old World" in the west and the "New World" in the east)
By the way, the dark/navy blue at the bottom of the western continent (Next to my small island there and below the brown, red and blue) is actually empty I think, since the previous claiming player there left.
