The Hanatenno are a collection of mysterious, skilled mercenaries who - usually - work for the betterment of Sanctuary. The name of their agents, the Tenno, inspire fear and awe in many.

The Hanatenno operate as a group of precision-strike agents who carry out missions of tracking, reconnaissance, stealth, subterfuge, and assassination. They are powerful, technology-inclined, and deadly in their execution.

Internally, there exists no leader. All of the group is selected on equal footing of one another, and all major decisions are decided with everyone's input into the issue. Usually in the field, the Tenno will designate a "shot caller" if they are in a group. This is usually someone who has knowledge of the battlefield and can deliver information to the rest of the team.

As far as allegiance goes, it's something of a mix of private and government-allied. The group works like a privately-owned business; they work under the banner of Sanctuary, and thus tend to respect the Authorities and their orders. However, they are also a private militant group, and thus can deny any orders given by Sanctuary officials.

The overall rules of the group boil down to two major tenets:

• Never compromise the group, no matter your current status within the group. 
• Never shed the blood of your comrades without due reason.

Both of these are considered to be the cardinal laws of the Hanatenno order, and are expected to be followed to the letter. Beyond that, all things are handled on a case-by-case basis.

The punishment for breaking the cardinals of the Hanatenno is known to be rather dire, with probation, imprisonment, decommissioning, or execution usually being the things to be pitched as retribution. The last usually isn't given unless one has grievously broken one of the tenets, but any of the first three could be.

The individual agents, the Tenno, make up the body of the group. They are a collection of warriors whom are chosen based not only on their skill, but their ability to perform as well.

Teamwork is necessary only when one is in a group. In fact, it's not rare at all that many Tenno work alone on various operations, as some are simply more capable doing so. In general, there will never be more than four Tenno fielded at once, as their numbers need to remain small for most missions.

The Tenno are, by necessity of their job, very adept fighters. They are expected to be at least competent in most broad areas of fighting, with a specialization or two being highly coveted and recommended. Excellence is preferred, but relative competence is the baseline.

Hand-to-hand combat is never an issue, as they are capable of performing well in close-range encounters. In conjunction with this, their skills in acrobatics and balance should be passable, if not great. This is to ensure that no Tenno is caught off guard when they are forced into a close-quarters engagement with anything.

In terms of things like weaponry, the use of melee-based weapons is required to be excellent. If not that, then they must be very adept at the use of ranged weapons such as firearms. If they excel in either, the other is allowed to be less adept, but they must still maintain a relatively good level of skill.

When a Tenno goes into the field, they are expected to uphold the honor and reputation of their organization. As such, the proper execution of a mission is necessary.

Cerebrally, Tenno are required to follow the orders given to them, think on their feet, make good decisions, and be capable of assessing situations. While some may be better than others at these, all are required to be able to do it.

Physically, they should be capable of executing these orders. They should have a clear knowledge of their technology and its capabilities, and operate them excellently.

While there is a technology used by every Tenno, it is allowed and encouraged that anyone joining the ranks have their own equipment to use when they go on missions.

The equipment used by the Tenno was created for the express purpose of giving them the power to combat magical and other threats in the name of Sanctuary.

The tools they use are extremely advanced personal units that attach to their backs, typically called an Exospine. This Exospine is embedded in the skin, allowing for it to sync directly with the body. The spine is, as the name suggest, a flat, mechanical spine that curves with the body. While also being very chiropractic, it gives a Tenno a range of power to deal with the threats they may find.

• Anti-Magic Personal Barrier: A magic negation barrier surrounds the user, distorting magic like an EMP and making it impossible to be tracked or influenced through mystical means.
• Shielding Barrier: A finite barrier of damage that allows for all forms of damage to be absorbed. The barrier can only take so much punishment, and will be destroyed if too much damage is taken at once.
• Physical Performance Increase: The physical capabilities of the Tenno are increased.

• Cloak: Once activated, the Tenno can become invisible and be rendered undetectable by visual-based technologies. Alongside this, their physical speed is increased threefold, allowing them to traverse areas extremely quickly.
