Sergeant Knight at Arms
Harlaus was surrounded and was the most likely king to hold feast during multiple invasions because Swadia position while It would be much rarer that a Kingdom on the border was invaded by many kingdoms during a feast.People "remember" those things because they were forced reddit memes from the unfunniest people on the internet. Jeremus was the only companion worth a damn so people turned him into a demigod in their minds. All kings held feasts too often but harlaus is the funny haha butter king so people made jokes about him over all the others, even though nothing in the code suggests he throws more feasts.
Most of people's collective memories from warband are enhanced by the memes people have built around it over the years, none of which are really based on the game itself, but rather redditor speculation from people who were mostly just guessing. Warband was just as boring and soulless as bannerlord, but since it was a janky game made by a tiny team and most people bought it on sale and went straight to mods, the playerbase collectively ignored how bad it was.
I challenge you to play an entire campaign of unmodded warband. If you don't blow your brains out by the end, you'll realise how poor the immersion is, and how little personality the NPCs and quests have.
