A man dies around 500 a.d. and goes to heaven, becomes an angel.
Returns in 1200 a.d. for an undisclosed period of time.
Returns in 1700 a.d. where story takes place.
Thoughts
Rayed know returns not fully appreciated
Time vampire, kind of in, kind of mins, kind of can’t fully control – human perspective does not always see the right path from the start
Roman or Greek Angel might be a bit common, big world reinforced bias not always ideal
Future less than ideals kind of in by design as a known (potentially makes crafting story more difficult)
Slavery, Civil War, WW1, WW2, Vietnam, and all the genocides from 1900 to 2024
Former rulers and emperors imperialism not fully sold as genocide, monstrosities that they were. Roman, Greek, and Egyptian empires. Nice statues and philosophy not all appreciation for Colosseum, slave trades and lives in the hands of the audience.
They gained more land and built aqueducts maybe an oversimplified view. Trading water for crucifixions not ideal value added.
Imperialism wind, Imperialism inned min-ed
A story that could be good, could be would, could be should
