Jedi

Jedi represent the good side of the Force in the Star Wars continuum.

They are dedicated to helping others and are the opposing number to the Sith.

Making a Jedi engage in a relationship (without evidence that they would break the rules) before the creation of the New Jedi Order by Luke Skywalker is a charge, unless your story is set before the Great Sith War. A character that is a Jedi must follow all rules that bind Jedi -- taking all bonuses and penalties of being one. A Jedi cannot use malicious/purely hurtful/Sith-associated powers (such as Force Lightning or other torturous techniques). Abusing force powers is also a strict no-no. Especially if trivialized.

It is nearly always a charge if a canonically stable Jedi turns and becomes a Sith -- only excusable in goodfic due to good execution.

In short, a Jedi is trained to act like a Jedi except in a few outstanding circumstances, and an unjustified break in Jedi behavior causes the character to be not only annoying but unrealistic and Mary-Sueish... especially if he/she gets away with it without something bad happening.

No-Fanfic Era
The earliest history of the Jedi is the sort of information that only more serious or involved Star Wars fans bother to research, as it involves buying fan materials and supplementary extended universe books. This limits the era's exposure to only a portion of the fanbase, and within that relatively small part of the fan community the population within that writes fanfic is smaller still. Meanwhile, more casual fans who would eagerly (or perhaps skilllessly) write fanfic of this era are unaware of its existence, let alone the details of it. This all adds up to a dearth of fanfiction regarding this era, for better or worse.

Origins
According to Wookiepedia, the Jedi began as a Gathering of the Galaxy's best Philosophers, Priests, Scientists, and Warriors on the planet Tython.
