Some of that fluff is a bit yikes. The Ottoman empire rooting out minorities via religious fanatics is not.... great. The Arabian nights themes used are also just a bit odd, and don't really fit the steampunk vibes, while the decadent dissolute sultan and the evil vizier scheming with organised crime is also just a bit cliche. The obsession with purity of blood and East Asian can only be ruled by despots is also... not great, while the mystical dream BS also offends my steampunk sensibility. Its all perfectly cromulent fluff, but the constant refrain of dark forces and mystical nonsense is not my idea of Victorian Sci-fi, and just a bit grimdark.
The other bit that doesn't make much sense is the idea that there is no war. The Japanese blow up Singapore and everybody just leaves vowing revenge? The first time the US and the Pan-Asian faction make contact is when the combined might of East Asia invades the Caribbean? Also the idea that you are sending a battleship on a stealth mission for a shadowy patron rather than the government doesn't make vast amounts of sense. How do governments keep covering up all these naval armadas going missing? I think the game should be push for total absurdity based on this, with your mission being to bring back the last Dodo for Queen Victoria's birthday etc.
