Chrailis - Military and Police

Military and Police Organizations of Chrailis
This is about the societal structure of the city. It can’t be stressed enough, Si’Nassapherion is such a powerful entity that she directly influences just about every aspect of this city.
There are no city walls designed for protection—no army has ever even considered attacking Chrailis. As such—there is not a standing army as we would think of one. There is no expansionism, colonialism, etc. What Si’Nassapherion wants to own and control, she owns and controls. The only real threat would be the possibility of a rival dragon trying to encroach on her territory. The nearest Dragon City lies over 800 miles away and has almost zero interaction. Additionally, Si’Nassapherion is on peaceful terms with all neighboring dragons—possibly related to several of them.
There are no large monsters terrorizing the countryside. She would consider a Terrasque a minor inconvenience to be handled before morning bell finished sounding.
She even has enough influence on the weather that there is no threat of major tornadoes or earthquakes affecting the city.
The rumors are that she is somewhat omniscient and most scholars agree. Having said that—she is an indifferent ruler to the smaller things. If a section of the city burns down, she doesn’t seem to care. If a major mine collapses, she is not there helping out. If a decent size group of monsters raids some nearby villages, she normally doesn’t respond. However, if the threat is the razing of a hamlet or village, she responds in force and often takes out the raiding party before the raid even begins. A lot of it comes down to the size and severity of the threat. Dozens killed - doesn't care. Hundred’s potentially killed or major landmarks destroyed—she cares quite effectively.
So the inhabitants of the city and countryside are left to fend for themselves from smaller events like fires, mudslides, small lizardfolk or kobold raids, and plagues. To this end, a city guard and standing militia exist. The exact hierarchy is chaotic and fluid—largely flat in nature in that while individual leaders may have a chain of command, they are left to their own devices for the territory they have been given charge.
The major groups are:
The Ivory Shields protect the inner two rings of the city. They answer directly to Marshall Skinner who in turns answers to the Council. Their name comes from the alabaster colored stonework the inner city is crafted from. The next three rings—with the buildings largely made of stone, are protected by the Stone March. There are roughly 4 groups, each led by their own Marshall. Two of them report directly to the Council, one to the Arcane Guild, and one to the 4th Tier Bank. From the 6th ring out to the final 18th wall, no less than 92 groups protect the city. Besides the walls, the buildings are largely a mix of wood, brick, clay, and stone. As such, these sections of the city are flammable and as such many of the 92 groups also work as firemen—with their pay and structure arranged in that manner. Collectively these guardians and civil servants are known as the City Guard.
Each group of the City Guard represents various interests and reports to various leaders. No group is autonomous unto itself, however. Some groups work primarily as peacekeepers, while others rent out as bodyguards, some work as firemen (as mentioned above), some are in charge of various municipal functions like sewage control and vermin removal. Some groups are racial and tend to guard their own section of the city. (There is an area known as the Centaur Halls that has roaming armed Centaurs walking their streets keeping the peace.)
Some sections outside the city have elaborate mines, and sometimes the mines are inhabited by large extended families of dwarves or gnomes. These groups may also have their own form of local constabulary.
All these groups, while independent of each other, work harmoniously with each other on the surface. Some are more corrupt than others.
This all alludes to the need for a justice system and a legal system. The Council will appoint judges—some stationary in the inner rings, some wandering in the outer rings from court to court. The city has a rather uniform set of laws—and for ease—just consider them similar to our common law with harsher penalties. The final group is the Rangers. Of all the groups, they are the largest. Think of them as grown Boy Scouts with Swords. Each small grouping is known as a Regiment and their size and total number vary at any given time as a function of need. Hierarchy within each Regiment also varies. As a general rule, each regiment consists of Rookies and Veterans. When one Veteran is experienced and is in charge of something like quarter mastering, training, setting up the campsite—they are referred to as Corporals. A Sergeant is usually over multiple Veterans and Rookies—often coordinating efforts of the Corporals. Then at the top of each Regiment is a Captain. For smaller regiments—like tracking parties looking for Lizard Folk raiders, there might just be a Captain, 1 sergeant, and a handful of veterans and rookies. Very few Regiments ever number over 30.

Promotion is often by seniority and by common consensus. As the Rangers are somewhat volunteer (no draft or conscription—just good pay and good adventure), a bad Captain usually loses his followers or ends up having an unfortunate accident. Any Ranger is free to leave his commission at any time. Any Ranger is also free to petition another Regiment to allow him to join. The only downside is that leaving a commission abruptly can cause loss of trust, privilege and honor should they try and return at a later day. Then again, some may never be allowed to return if it was due to blatant cowardice. Ranking doesn’t transfer from Regiment to Regiment. A Sergeant in one regiment might not be obeyed by the veterans in another command and this would largely depend on need and respect.
In the Rangers, a varying number of Sheriffs exist over the various Captains. Each Sherriff is elected by the Captains annually or as the need presents itself. Sheriffs all report to the one of 4 Lieutenant Marshalls.
Each Lieutenant Marshall (usually just called Lieutenant) is elected by the Sheriffs every 4 years, staggered so that a new one is elected every year. And all 4 Lieutenant Marshalls elect and Grand Marshall every 5 years, who answers to the needs of the Council. All such votes are group social events often involving copious amounts of alcohol.
While many rangers may live in the portions of the city, they all operate out of the cities. Some regiments have made names for themselves with storied histories. The Darkrunners, numbering almost 50, are well renowned for rescuing those in collapsed mines. The ScaleBanes are notorious for hunting down renegade groups of Lizard Folk and Plantmen. The Wily Warders are commonly called upon for armed escorts and quick rescue of lost groups in the wilds.
As a final note—I am not aware of anywhere in history with a society set up like this—largely due to that I can’t find anywhere in history which has such a powerful protective force with little to no viable threat from the outside. If you can think of any good examples, I would love to further look into them for inspiration and I prefer to borrow from historical examples when possible.
