- "On Felucia, the Seps dug their metal heels into the muck of that alien hellhole and dared the Republic to come in after them. So we did, only to be met with month after month of flesh-eating diseases, shrieking nocturnal predators, and other sights that haunt me to this day..."
- ―Anonymous 501st Clone Trooper
Felucia had a diversity of bizarre plants, fungi, and animals which were almost rubber-like and translucent, as well as enormous Pitchers. When the sun shone, the environment glittered like multicolored glass. Most of Felucia was entirely covered by a humid, fetid landscape of huge fungal forests, and its wildlife included native gelagrubs, immigrated acklays, and a prodigious sarlacc. Felucia had strong ties to the Living Force, and as such the world's flora and fauna, including Felucians, could be influenced by a presence of a stong Force-user, both light and dark. Most plants and animals of Felucia have adapted special defences to protect them from each other, which made them particularly hostile to the off-worlders.
Felucia was colonized by the Gossam in 40,000 BBY[source?], early in their interstellar history. Felucia was a hard planet to colonize because of its dense forests and creatures. When the Gossams tried to colonize it, many aggresive plants and animals tried to defend the planet, but the Gossams finally gained a few footholds on it. Felucia was one of their earliest colonies, though it was one of the least populated since its vast fungus jungles proved too wild to support large Gossam colonies. As such, the planet became little more that an exotic retreat world for the wealthy Gossam along with their lowly servants and laborers. The planet was entirely controlled by the Commerce Guild, and resistance to the Guild was found in scattered townships in the wilderness. These townships were home to escaped workers, criminals, and enemies of the Guild.
When the Gossam colonized Felucia, the native Felucian species went underground or lived in small villages in the thickest forests. Many, if not all, of the Felucians were Force sensitive, and had a communal relationship with the planets ecosystem.
During the Clone Wars, Felucia became the headquarters of the Commerce Guild which supported the Confederacy of Independent Systems. Felucia would become a valuable member world and was as a result named by Supreme Chancellor Palpatine as part of a "Triad of Evil," alongside Mygeeto and Saleucami.
The planet was attacked during the Outer Rim Sieges. After the first attack, 19 BBY, Barriss Offee and Zonder were imprisoned on the planet. Aayla Secura took the Intrepid to Felucia to capture Shu Mai and rescue Barriss and Zonder; meanwhile, the Separatists began their attack on Coruscant.
With the help of Padawan Ekria, Aayla rescued Barriss and Zonder from the Nigkoe Detention Facility, resulting in a full-fledged ground battle. The Republic forces then assaulted Shu Mai's personal compound, not realizing Mai had already evacuated and was on Utapau.
The Jedi infiltrated the compound, found Mai long gone, but managed to shut down the droid army remotely, letting Commander Bly's clone troops into the compound, at the same time the Invisible Hand was crashing onto Coruscant.
Unfortunately, the compound was booby-trapped, and released toxins, killing many clones. The Jedi barely escaped before the entire compound exploded, but many clones did not. The trap also triggered a "poisoned well" policy to keep the planet from being of worth to the Republic, unleashing a highly poisonous biological agent into the water supply of Felucia's natural planet-wide aquatic distribution system, capable of infecting the entire planet in four days.
Shu Mai had left behind forces ordered to fortify the planet's major water treatment facilities. They knew the only way to prevent the deaths of millions was to take over the facilities and contain the toxin. The Jedi Council sent Stass Allie with clone reinforcements to Felucia.
Stass dropped off the clone reinforcements and Padawan Drake Lo'gaan on Felucia and then headed to Saleucami. The Republic forces split into three forces, each headed toward a different facility: Barriss, Lieutenant Inc, and Lieutenant Barr to Har Gau; Ekria, Zonder, Drake, and Lieutenant Galle to Jiaozi; and Aayla and Commander Bly to Niango.
Barriss's forces defeated a Commerce Guild patrol, at the cost of Lieutenant Inc's life. Barriss ordered Lieutenant Barr's troops to abandon her and go get Lieutenant Galle for help.
Meanwhile, Lieutenant Galle used a staged retreat to distract the Commerce Guild forces from the facility at Jiaozi, which the Padawans were able to infiltrate. The Padawans completed their mission at Jiaozi by shutting down the outgoing pipes before the arrival of the toxin, but were unable to access the controls of the Niango and Har Gau.
Ekria was puzzled when she detected a Confederacy-encrypted holo from Coruscant being received by Bly, not understanding that it was Darth Sidious relaying Order 66. Ekria was able to tap into the clone-cam feeds of Bly's troops and behold Aayla, who was spooked by the complete silence of the wildlife as she and Bly headed towards Niango. As Aayla was distracted by a native bird taking to the air, she was gunned down from behind by Bly and the other clones.
Simultaneously, Barriss was fighting alone, surrounded by droids. To her relief, she saw Lieutenant Galle's men seemingly rush to her rescue, but instead they shot her down.
The Padawans were horrified by Aayla's murder, but able to decrypt the message and hear Order 66. They then heard a new message on Republic channels from Coruscant: "Calling all Jedi. This is Supreme Chancellor Palpatine. The war is over. I repeat, the war is over. All Jedi are ordered to return to the Jedi Temple immediately. You will receive further instructions when you arrive."
The Padawans then checked Galle's clone-cam, and saw that Galle's troops were about to burst into the Jiaozi facility to kill the Padawans. The Padawans barely escaped, and would later head to Coruscant.
Since their defeat, separatist remnants, including Gossam settlers found shelter in small enclaves in the fungal wilderness, joining forces with fugitive laborers, outlawa and amugglers they formerly persecuted.
After the Clone Wars, the damage to the eco-system combined with the pain and suffering felt on the planet caused many of the force sensitive Felucians to teeter dangerously close to the dark side of the Force. This made Felucia an even more dangerous place. The Empire would occupy Felucia sometime before the Galactic Civil War. The Imperial forces maintained presence in Kway Teow primarily to gather Gossam slaves for export and to research biological agents takes from diverse and abundant plant life.
During the Great Jedi Purge, Darth Vader sent his "secret" apprentice Starkiller to Felucia to deal with Force-sensitives there. Master Shaak Ti had exiled herself to this planet, where she was training the grief-stricken Padawan, Maris Brood, and Felucians for a confrontation with the Dark Lord. The Empire began operations on the planet to eliminate the native Force sensitives and established a prison facility, from which agents of Bail Prestor Organa rescued Admiral Gilder Varth.
During the Galactic Civil War Jabba Desilijic Tiure had sent a Sith holocron that he spent half his wealth on to Felucia to be protected by the Empire, where it was stolen by the Zann Consortium. It was during this time that Tyber Zann here led a contingent of his underworld mercenaries against the Imperial forces. However, Zann would get captured by Imperial forces as part of a trap set up by Jabba, although he would later escape.
