Charr farmers can be many things. They may be Charr who weren’t good enough at combat in the Fahrar to be soldiers, therefore placed as farmers, elderly, retired soldiers, or Charr soldiers who are injured and are working as farmers while they recover, however, injured Charr soldiers can also be placed as Primuses or Quaestors while they heal, so its not an exclusive role.
All Charr (except free agents), are in warbands. Otherwise, they are gladiums. This means there are warbands who specialize in everything. There are warbands of merchants, miners, quaestors, farmers, smelters, prison wardens, engineers, armourers, whatever role that would potentially aid the legions, there is a warband for it.
Gladiums normally do nothing, because being in a warband is just how Charr society functions. If you have no warband, then you are a nobody. The issue is with this, finding a second warband if your Fahrar-made warband kicks them out, or they die is very hard, because you have to fit in with a group of people who have been together since cubhood, which is very difficult in itself, and its difficult finding a warband who will accept new recruits. Its particularly hard if the warband has died, and they’re the sole survivor, because it raises the question if they abandoned their old warband to let them die, which is basically the biggest no-no in Charr society. Its more honourable to die trying to save your warband than leaving them to die in order to save yourself.
That leads me to another question: do gladium even receive assignments from the legions? With the exception of Rox, who seems to be an unusual case, every one I can think of we only see loitering, trying to join a new warband, or pursuing personal objectives.
Gladium are out-of-the-loop of regular legion activity. Some of the gladiums are punished for whatever they did to become gladiums, such as Vere The Coward, who’s punishment is to tell the story of how he abandoned his warband to anybody he meets, however, Gladium who attempt to apply to join another warband may be sympathised with, so officers such as Legionnaires, Centurions or Tribunes may make arrangements to help a Gladium find a new warband.
Rox’s situation isn’t unique, but is rather rare. She’s described as a “solo agent”, which means she still acts under the legions as a soldier, but she doesn’t have a warband. The reason she has this status is because she applied to The Stone Warband, and she was asked to complete a series of tasks to prove she is worthy to join the warband, however, part of these tasks was to do them alone, hence why she is a free agent.
Rox isn’t a free agent in the present day however. Her final task was to kill Scarlet Briar, however, she chose to save Braham who needed help at the time, and the Player Character beat her to the kill, meaning she was refused from the Stone Warband and chose not to re-apply, ignoring any further summons from Rytlock Brimstone she received in the mail. She currently sits as a Gladium, shes had no further interaction with the legions since then.
Although Rox is the only free agent Charr to date, I imagine it can be given to certain other Charr also, for example, I imagine certain Charr who do specific assassination jobs might be free agents, because a team can sometimes get in the may more of such a job than if they were alone, however, most Charr agree that a warband is the optimal situation, which is why free agents are very rare.
Lots of lovely damage.
