I like the idea that was mentioned earlier about contracts regarding ‘specialized’ encounters.. for example. maybe for one of the ‘townsfolk have been disappearing’ events, you’re hired to track down a ‘killer on the run’. You could go several ways with that type of encounter:
1) The killer could be a special/named unit, but otherwise just be your typical engagement.
2) You could base a secondary event off of this event, where once you have found the killer you have the potential to resolve the contract by convincing the killer to join your company (similar-ish to the deserter event during the noble war).
You could do this for a variety of things.. poachers, thieves, killers, a particularly nasty direwolf, etc. Would add some great variety and a bit of ‘life’ to the contracts.
