Kind of like what you'd see in a fantasy or RPG story. People who go around, adventuring and fighting and generally just solving problems for money.
Obviously it's not like in a video game or something, I highly doubt people went around fighting monsters and saving the world, but were there actually people who made a living by going around and solving various problems rather than, say, sticking to a specific trade?
Hi, not discouraging others from answering here, but to get you started, check out these threads
/u/Rittermeister in In games and books there are always "adventurers" who do odd jobs and explore for a living. Did something like this ever actually exist in medieval times?. As an aside, I see that I pasted a block of links to threads about mercenaries in there; no doubt those links should be pruned aggressively by now, so just a heads up that some threads may not pass current subreddit standards.
/u/AncientHistory in Was "adventurer" (in the Dungeons and Dragons sense) ever an actual profession in medieval Europe?
/u/restricteddata in Did 'brave adventurers' actually exist during the middle ages, or is it just a videogame trope?
As a follow up question, the answer I have read seem to be focusing on medieval western europe. Were things differents in the byzantine empire?
