When on watching GT, it seemed like it happened soon after.How long after the Baby arc?
Only for the first arc, the black star dragon balls and the transition to the Baby Arc. Everything else? There's a short gap between baby and 17 arc and shadow dragons happens literally right after 17 arc ends chronologically too.That's what I thought too, though it feels like the entirety of GT takes place within a very short amount of time. I'd have to assume there were longer gaps in time than it appeared.
