The current calender counts from the year that the Scarlet Empress, the ruler of the Realm, saved the world from the Balorian Crusade, a massive invasion of the Fey in the wake of a massive die off caused by the Great Contagion. 9 out of every 10 creatures died to the Great Contagion.
It is Realm Year 758. The undisputed Super Power of Creation is the Realm. Ruled by the Scarlet Empress' iron fist, it extorts tribute from nearly every state formation in the world. The only ones to escape the Realm's overlordship are the insufficiently re-explored Western Islands, and the River Province and the Eastern Direction behind it. As it's official state religion is the Immaculate Order, you doubt you'll be able to get Liberalism off the ground in either it or it's satrapies. They will not take kindly to a spirit like you starting massive social and economic changes.
Of the independent realms, you have identified three places with potential for you to start your revolution.
The Kingdom of Terek is the largest state formation in Creation to have banned slavery. It's royalty bases it's legitimacy on it's ability to keep it's subjects safe from the many dangers of creation, rather than any inherent right. And it has a Deliberative to advise the king. The Deliberative isn't as powerful as Parliament was prior to the English Civil War, but it could become so if things fell out the right way. If you want to start a social movement, this kingdom is the most fertile ground.
The City State of Great Forks is a theocracy ruled by actual gods. It is a slave state, keeping them in line with brutality and drugs. It is famously debauched. It is also the greatest center of learning in the River Province. If you want to kick off the Scientific Revolution, this is the place to form the social connections with the great scholars of the age to do so.
Nexus is the largest city in Creation, rivaled only by the Imperial City. It is a place of commerce and violence. It is the headquarters of the Guild, the premier merchant league in Creation. It is run by an unelected oligarchy, who maintain they set no laws even though they totally do. It has the largest middle class anywhere in creation, and labor is cheap. Introduce the Bessemer Process and the Factory System, and starting the Industrial Revolution would be relatively easy.
