Qui-Gon Jinn played by Jim.

Qui-Gon is a Jedi knight.

Jim is a rather gung-ho roleplayer, interested in action, cool fight scenes, and lucrative spoils over careful consideration or puzzle solving. He frequently acts before he thinks, which includes fixating on his own strange explanations for setting details that the GM hasn't explained yet.

Obi-Wan Kenobi played by Ben.

Obi-Wan is a Jedi padawan, apprenticed to Qui-Gon.

Ben is a thoughtful roleplayer who tries to think through the best course of action within his character concept and the setting. He enjoys coming up with clever ways to justify the success of his plans within the premises of the setting.

Jar Jar Binks played by Sally.

Jar Jar is an alien native of the planet Naboo.

Sally is Ben's younger sister. Ben took her along to the game one evening when his parents couldn't get a babysitter for the night. The GM quickly generated an alien character for her to play so she wouldn't get bored. She enjoys the make-believe aspect of the game, but has some trouble separating it from reality.

R2-D2 played by Pete.

R2-D2 is a droid mechanic, initially in service on Queen Amidala's royal yacht.

Pete is an old friend of Jim's. Jim invited him along to join in this new game. Pete designed a character to maximise all the skills he thought would come in most useful in a space game, at the cost of being a short, squat robot with no arms.

Shmi played by Annie.

Shmi is Anakin's mother, and a slave of the junkyard owner Watto.

Annie is an acquaintance of Ben's, who attends his drama classes. She was interested to come along and see what this "roleplaying games" thing was all about, after Ben described it to her as a sort of improvisational acting thing. She is dedicated to playing her character as a real, complex person with motivations inspired by a well-considered backstory.

Anakin played by Annie.

Anakin is a young slave boy who worked in Watto's junkyard on Tatooine. He was an unimportant throwaway character that the GM inserted merely for colour in one scene. Annie took over playing him after the Jedi took Anakin with them, leaving his mother behind on Tatooine.

Boss Nass.

Boss Nass is the leader of the Gungan species on Naboo. He rules from Otoh Gunga, an underwater city. His main concern is recovering the mystical Lost Orb of Phanastacoria, a powerful Gungan artefact capable of protecting his people from any attack.

Sio Bibble.

Sio Bibble is the Governor of Naboo during the reign of Queen Amidala. She trusts him implicitly, but Qui-Gon suspects Bibble is up to some sort of nefarious plotting behind the throne to take absolute power into his own greedy hands. Who is right remains to be seen.

Queen Amidala.

Queen Amidala is the absolute ruler of the human population of Naboo. She is 14 years old, and was elected to the office of Queen due to her great wisdom and popularity. How exactly she gained these at her age is a mystery.

Captain Panaka.

Captain Panaka is Queen Amidala's bodyguard and leader of the Royal Security Forces of Naboo. As such, his job is to keep the Queen out of trouble, which seems to be a very difficult thing to do with Jedi knights around.

Padmé.

Padmé is supposedly one of Queen Amidala's handmaidens, instructed to accompany the Jedi on their adventures. She is really (but unbeknownst to the Jedi) Queen Amidala, incognito.

Watto.

Watto is a junkyard owner and pod racing driver on Tatooine. He owns Shmi and Anakin as slaves, and gets Anakin to repair his pod between races. He is a Toydarian - a flying blue alien.

Ric Olié.

Captain Ric Olié is Queen Amidala's personal pilot. The GM often uses him as a character mouthpiece for the exposition of scene-setting description that is not apparent to the players - although their characters would find it perfectly obvious since they can see it themselves.

Chancellor Valorum.

Chancellor Valorum is the leader of the Galactic Senate. Although a worthy man when elected, he has been corrupted by power and is losing his grip on reality. This manifests as eccentric behaviour.

Senator Palpatine.

Senator Palpatine is the senator for Naboo in the Galactic Senate. He is a kindly man, genuinely concerned for the welfare of the Naboo people, and for the peace of the Galaxy as a whole.

Mace Windu.

Mace Windu is a Jedi Master and one of the members of the Jedi Council.

Yoda.

Yoda is a Jedi Master and one of the members of the Jedi Council.

Darth Maul.

Darth Maul is a mysterious operative in the employ of Senator Palpatine. He works alone.

Nute Gunray.

Nute Gunray is the leader of the Trade Federation. He is a cool, calm, and collected strategic genius. Unfortunately he talks in a bad pseudo-eastern-Asian accent, which the GM uses to indicate that he comes from a different cultural background.

Dofine.

Dofine is Nute Gunray's second in command in the Trade Federation. He tends to panic when things are not obviously going their way, but Nute Gunray's cool command usually takes care of everything.

C-3PO.

C-3PO is a translator droid built by Anakin out of spare parts from Watto's junkyard. The GM added C-3PO as a mitigator to R2-D2's lack of speech capability, but quickly reversed his decision when it became clear just what R2 wanted to say about the campaign so far.

Captain Tarpals.

Captain Tarpals is a Gungan military commander.

Sebulba.

Sebulba is a pod racing driver on Tatooine. He enjoys soup and sabotaging other racers' pods.

Dan and Olaf Annodue.

Dan and Olaf Annodue is a two-headed sports announcer, who calls the pod race on Tatooine.

TC-14.

TC-14 is a protocol droid who acts as a servant to the Trade Federation leaders on their orbital headquarters ship orbiting Naboo. He is assigned to serve the Jedi drinks before their meeting with Nute Gunray.

Gragra.

Gragra is a frogmonger in the Tatooine marketplace. She complains when Jar Jar tries to eat one of her frogs without paying.

Sand People.

The Sand People are a race of desert dwellers on Tatooine. They wear heavy cloaks and face protection against the harsh desert suns. Qui-Gon gives them weapons to shoot at pod racing drivers during the pod race.

Greedo.

Greedo was a young Rodarian boy on Tatooine. He used to bully Anakin and his friends sometimes. After the pod race, Anakin finally took revenge in a fist fight that got out of control, resulting in Greedo's premature death.

Jira.

Jira is an old woman who sells stuff in the market on Tatooine. She is the last person on Tatooine who Anakin speaks to before leaving home, and warns him never to return, or else the Hutts will catch him for murdering Greedo.

Dib Foundway.

Dib Foundway is a spice farmer from Kessel, who spent his last credit to come to Tatooine seeking a new start. But then he gets caught up in Jabba the Hutt's criminal machinations—the backpack contains a new variety of spice he grew himself—and eventually winds up murdered in Mos Eisley by the father of Hojon Intigua, the cantina owner in Episode IV. It's in one of the comic books.
