Steam Ghost

This is a world built on anomalies and steam. The vast majority of people are gathered in huge cities made of steel, gears and steam. After 1,500 years of the battle royale era, mankind finally found a place to live in 1579 AD, at the moment when the first steam engine was born. Since the lost era, when history was once again continuously recorded, mankind, which had been running away, could finally stop and rest, gear up, and move towards a new era - the age of steam. —————— Newbie, please give me advice.
