Context: I usually play with ironman off and the community flavor pack mod, but I decided to do an ironman playthrough. I sorted achievements by rarity on the Xbox App and the Daurama Daura one was the rarest, so I decided to try that. Still haven't done what I need to gain the achievement but I'm on my way. Regardless, I went from a realm size of 2 to 74 in the spam of around 50 years, mothered 12 children, founded an empire and several kingdoms and became the most powerful nation (military strength) on the map at the moment.

Ironman, normal difficulty, all settings set to default except Diplomatic Range - Restricted, Exclave Independence - Total, Regional Heresies - Strict.

Just wanted to share cuz I was somewhat proud of it, even though it truthfully wasn't very challenging, and that's not a humble brag.
