My suggestion is that for each era we have a new topic category named Contracts. here people can create their own targets for people to assassinate or create a job that needs doing such as escorting a wealthy assassin arms dealer. Once the contract has been completed it gets labelled complete and then no one else may take it (as the target is quite dead)
the template for contracts would require:
Name: eg bob bobbington
job type: eg assassination
affliction: eg Templars
description: eg dark hair, blue eyes, wears silver locket
job details: eg Bob bobbington has been funding Templar operations by taxing the people unjustly.
I would happily run this topic section if needed. I think this could really be beneficial
