Randomly thought about this idea. What about a bounty board/notice board with radiant quests that can be completed for a minor sum of electrum? Maybe have the bounties accessible after a certain progression threshold, and perhaps limit the bounties to "x" amount of bounties per "y" days/weeks, so it can't be abused too much in a short span of time. When the bounties run out, it can say something like: "There are no more bounties for now, you should check back in about a week to see if any more are posted.".
Optional radiant content like bounties can indirectly serve as an artificial increase to the length of the game for those that utilize them, since partaking in bounties or renewable miscellaneous activities can fill the gap between major quests, just adding to the overall number of things that the Champion can do throughout the game.
For roleplaying/balance purposes, the board itself it could tie in to the acquisition of Wayfort, or maybe part of it's eventual construction (or maybe a future location/structure that hasn't been implemened yet), or in Hawkethorne somewhere, or maybe have River give out the quests with brief dialogue. Whatever the case, in my eyes, it'd make sense that the Champion could receive a modest reward for your "continued efforts of ensuring the safety of the roads".
Though this idea will probably be more appropriate when there are more "money sinks" in the game. Just spitballing some random thoughts on it.
As an aside, I'd love to see more content for Atugia.
