Seems to be that the following nations are extant:
- India (or rather, Anglo-Indian kingdom)
- France (outre-Mer)
- California (USA, albeit a theocratic bunch of cities resembling the bible Belt)
- Egypt ????
- Spain (now a small city-state)
- Dominion of Braganza (Portugal???)
- Bavaria (Germany???)
- Batavian Republic (Dutch)
- South Africa
- Syrian Empire
- New Afrika
- Gran Colombia
What's the premise?
It's 100 years since the events of The Peshawar Lancers. The world has recovered, and things are reaching pre-Fall levels. Steamships and airships are still all the range.
