First off let me explain that warriors aren't chiseled in stone. There are varying views, location and environment, number of other setites, and nitch. There are a few common archetypes warriors fall under Temple Guard, Hunter, Assassin, Body Guard, General, and Gladiator. I'll expand on each one of these individually. Each requires it's own attention. Also some of these concepts transition through role-play into other archetypes. This is very common because all characters evolve just like people do from their experiences.
        Also note that warrior concepts come in two flavors and are not restricted to the warrior bloodline. The bloodline is a setite dedicated to the arts of war and has been gifted as such by the blood of Set. These warriors differ from a normal Setite in that they get an inherent combat discipline of potence. Where as standard Follower of Set has to find a teacher for potence but still has Obfuscate at his disposal.
        Not all warriors are Fanatical martyrs. Some of them are face men or secretive hunters. Every warrior should have a unique personality. But then so should every character.

Societies and cults
        There are warriors in each cult and with in the cults their duties and purposes differ. A warrior who holds a regional society title is responsible only for his region and the protection of the regional temple and priest. A warrior in a minor or major cult may only be responsible for the defense of its high priest or training of new initiates in martial prowess. Needless to say no one warrior position is the same. In some instances a regional priest may dictate a regional warriors positions duties and in others the warrior is more likely to be in charge of the region. This is pretty much a very flexible organization.

Individual respect and prestation
        Warriors can be prideful or modest. A warrior of the bloodline may show disrespect to non-bloodlines but that is character preference. Some non-bloodline warriors have attained much acceptance and respect where those of the bloodline have done little but sit and guard a temple. Either way each warrior should know that they are doing their part to serve set. Regardless of how they do it each knows that their role increases the chance of Set's return.

Other tips
        Don't make it obvious that you're a warrior. The general populous doesn't know how many warriors there are and no lore but setite lore covers warrior bloodline. Announcing that you're a warrior marks you as a target and a threat. "The priest is harmless but the warrior could kill someone" would be a misconception that could be fatal for a character. Do your best to be either an enigma or find a way to create lots of misdirection. It's none of the Aeons business what you do for the clan.

Archetypes

Temple guards
        These could be new initiates that haven't earned their place out side the temple. This isn't to say that all temple guards are young pushovers. Someone has to be in charge of them. This is a good role for a neonate or young ancilla warrior. Temple guards usually aspire to one day become one of the elite guards at the national or global temples.
        Elite Guards, these are more likely to be fanatical in how they fight and serve set. These are not novice warriors but proven hardcore veterans. They only serve in grand temples at some regional levels but usually not lower than national. These are the guards everyone should be afraid of. Their martial and military discipline is as legendary as Set himself.
        Suggested research material for temple guards, Look into the Catholic Vatican in Italy. They have their own religious temple guards who are trained in martial prowess.

Body Guard
        This is a warrior that is either a mercenary or the personal guard to a priest. I'll elaborate on each one.
A personal guard to a priest is in charge of the safety of on particular individual, usually a priest. They take on the full responsibly of keeping this person safe from all harm. Priest personal guard is more likely to die in order let the priest escape than they are to betray the priest. Mitigating circumstances do happen to prevent that. Like the warrior feeling that the priest has been lead astray from the teachings of set. But all in all this warrior goes wherever the priest goes to ensure their safety.
        A mercenary is an accomplished warrior who sells his ability to whom ever needs a guard. This seems off kilter from the whole war against the Aeons thing but it isn't. By helping an Aeon he is making that Aeon more comfortable with a follower of Set and that Aeon may eventually seek Set's enlightenment from the warrior. This is one of the many ways for a Setite to gain favor from Aeons as well as betray them. Also these warriors have magnetic or chameleon like personalities to fit in, in any social setting.

Gladiator
        Now this looks out of place and that it may not fit the paradigm but it does. There are ancient snakes still around from the roman era. These snakes ran private gladiatorial fights to seduce the Aeons or kill them in the arena pits. During this time there were many gladiatorial Warriors whose prowess was noted for how good a show they put on. Think WCW and you got it. Except Gladiator snakes weren't likely pitted against each other but against Aeons like brujah, Ventrue, and Gangrel.
        One common beginning is that these warriors started out as slave ghouls that fought in the Circus Maximus until they earned the embrace. Or they could be a product of the modern boxing rings or pit fights. Anyplace and time were people battled for the entertainment of others.
Modern day we see movies about street fights and pit fighting. Who's to say that modern day kindred to enjoy the same past time?

Hunter
        I'm not referring to the mortal hunters but to the idea of a big game hunter. This is a warrior who has taken it upon himself to hunt down and slay the Aeons to sacrifice them to Set. These warriors tend to operate in small coteries to make surgical strikes so well orchestrated that there is a minimum chance of failure. These hunters keep trophies and are less likely to brag about a kill. They hunt for Set not personal pride. These warriors are likely to learn out of clan animalism instead of presence. It is a more useful power when hunting down kindred, gathering information, and setting up the kill zone.

Assassin
        This is a more specialized hunter type. This Setite is more likely to operate alone or in very small cells and strike important court officials or high profile clan enemies. This doesn't meant that he has to kill the target but has the ability to make sure events fall into place and the target gets destroyed. There is one common tactic that destroys a target's character. That when he is finally slain it looks like a mercy killing as apposed to murder. A good example would be setting a chain of events that gets a well-known kindred bloodhunted and then swooping in and killing the target

General
        These are elder warriors that have survived many a war campaign. These are the ones that are National warrior heads or likely regional warrior heads. They lead during times of war and great battles organizing dozens if not hundreds of Setite warriors. These are the venerable ones capable of maintaining both logistics and knowing the best distribution of their assets. That's not to say they aren't formidable combatants themselves. They only attained this rank through proving themselves over and over again.
