A holocron attributed to Asli Krimsan is a device created by Jedi Master Asli Krimsan sometime before the Battle of Yavin, possibly millennia prior. Krimsan originally placed the device within the Jedi library situated on Exis Station located in the Teedio system. After the Jedi abandoned the library, the holocron was eventually moved to the Jedi Temple on Coruscant where additional teachings from other Jedi Masters were recorded on it over time.
Later, the Dark Lord of the Sith Darth Vader came to possess Krimsan's holocron and kept it within a secure vault inside his personal quarters at Bast Castle on Vjun. Following his death, the holocron remained there until it was discovered in 22 ABY by Jedi Knight Tionne during one of her many research expeditions. On this particular mission, she was accompanied by Jedi Master Ikrit and Jedi trainees Anakin Solo, Tahiri Veila, and Uldir Lochett. At the castle, the Jedi team encountered the "Mage" Orloc, who attempted to steal Krimsan's holocron from them. The Jedi defeated him and returned the holocron to the Jedi Praxeum on Yavin 4. Lochett later stole the artifact when he fled the academy to seek instruction under Orloc, but it was recovered when Orloc was revealed as a charlatan aboard Exis Station.
The holocron of Asli Krimsan was designed in a cubic shape and was compact enough to be held in a single hand. It had the capacity to store vast quantities of information within its crystal matrix. The device's exterior was pearly white, and it was capable of projecting color holograms. While the holocron typically projected smaller images, it had the capability to produce an image large enough to fill a room thirty meters tall and wide. It was primarily intended for use by Jedi Masters, though any Force-sensitive individual could activate it and interact with the holographic gatekeeper. The gatekeeper was a simulation of the Jedi Master Asli Krimsan, appearing as a small humanoid woman with black hair and smoky topaz eyes, dressed in a red gown.
The main purpose of Asli Krimsan's holocron was to serve as an educational resource for Jedi children. It was designed specifically for use by Jedi Masters who taught very young Force-sensitive individuals. It contained both Krimsan's personal insights and recordings of lessons from other Jedi Masters. Additionally, Krimsan's holocron included information on historical battles between the Jedi and the Sith, Darth Andeddu, and advanced Jedi Force techniques such as Malacia.
Krimsan possessed over two centuries of teaching experience at the Jedi Temple on Coruscant when she recorded her holocron. Upon activation, the device would immediately begin a lesson by Krimsan on Jedi meditation techniques. If interrupted with a question, the gatekeeper would provide other lessons or insights as requested. For example, when the holocron was in the possession of the New Jedi Order, the gatekeeper was asked for her opinion on the Potentium, a belief held by many Force-users that the dark side did not exist. She strongly rejected this belief, stating that the Potentium approach was not in line with the Jedi way. Other recordings were also stored on Krimsan's holocron. Two notable examples were a lecture by Jedi High Council member Yarael Poof on the proper use of the Jedi mind trick, and a story by Jedi Master Dooku about how he developed a better understanding of telekinesis as a child.
The Jedi Master Asli Krimsan, a teacher of young Jedi for over two hundred years, crafted the holocron. She compiled her teachings and stored them in the device to benefit future generations of Jedi teachers and students. Krimsan placed her holocron in the Jedi library on Exis Station, which housed Jedi records salvaged from the destruction of the Great Jedi Library on Ossus in 3996 BBY. Due to hazardous radiation and solar flares, the station was abandoned thousands of years before the Battle of Yavin, leading to the transfer of Jedi artifacts, including Krimsan's holocron, to Coruscant or their distribution among the Jedi of that era.
In the century or so leading up to the Great Jedi Purge, Krimsan's holocron was part of the collection within the Jedi Archives on Coruscant. During this period, additional lessons from Jedi Masters such as Dooku and Yarael Poof were added to the holocron. The Jedi Jax Pavan once studied the holocron in the Archives and encountered Anakin Skywalker during his studies. The holocron later appeared in a dream he had about their meeting.
During the Galactic Empire's rule, the Dark Lord of the Sith Darth Vader obtained Asli Krimsan's holocron. Despite the device not being mentioned in any of Vader's records, he kept it in Bast Castle on Vjun. It was stored in a secret vault within his personal chambers, adjacent to his sleeping tube. In 22 ABY, the "Mage" Orloc discovered that Asli Krimsan's holocron was located in the castle. Vader had also stored Obi-Wan Kenobi's lightsaber in Bast Castle, and rumors of that artifact drew a Jedi team to Vjun shortly after Orloc arrived to claim the two Jedi relics.
The Jedi team, led by Tionne, included Jedi Master Ikrit, Jedi trainees Anakin Solo and Tahiri Veila, the droid R2-D2, and Solo's friend Uldir Lochett. While they did not anticipate significant resistance as they searched the castle, they encountered a laser trap and a holographic death trap during their exploration. Behind the holographic trap, Anakin Solo discovered a secret door leading to a secret chamber containing Obi-Wan Kenobi's lightsaber.
Meanwhile, Orloc was also searching the fortress. He had found plans to Bast Castle in a maintenance bay and used his knowledge of its secret doors and passages to his advantage against the Jedi, stealing Kenobi's lightsaber and causing Tionne and Ikrit to fall through a trapdoor. Solo, Veila, and Lochett chased the Mage, but split up when he evaded them. Lochett was the first to confront Orloc. They spoke while Orloc threatened him with the lightsaber. The Mage boasted of his powers to Lochett and revealed to him the presence of Krimsan's holocron in the castle.
After the Jedi team reunited and forced Orloc to retreat, they searched Darth Vader's personal quarters for the holocron. Solo discovered the secret vault that held the holocron behind Vader's sleeping tube. The vault opened to his touch and voice command, and he was able to remove Krimsan's holocron. At Lochett's request, Tionne activated the holocron to see if it was operational. While the Jedi were examining the artifact, Orloc returned and stole it from Tionne's hands. He attempted to escape through another set of doors and opened more trapdoors in the floor in an attempt to slow down the Jedi. However, R2-D2 closed the doors via a control panel before Orloc could leave the room, and the Mage lost his balance and fell through one of the trapdoors. Before he fell, the Mage dropped Krimsan's holocron, which was caught by Lochett. The Jedi team then returned to the Jedi Praxeum on Yavin 4, having successfully retrieved both Krimsan's holocron and Obi-Wan Kenobi's lightsaber.
Upon Tionne and her team's return to the Jedi Praxeum with Krimsan's holocron, Luke Skywalker welcomed them back, but he soon had to depart on another mission. While awaiting Skywalker's return, Tionne decided to reward Anakin Solo, Tahiri Veila, and Uldir Lochett for their assistance in retrieving the holocron by allowing them to observe as she began to explore its secrets.
Activating the device, Tionne requested the gatekeeper to speak about herself. The gatekeeper informed the Jedi about Asli Krimsan and the purpose for which the holocron had been created. In doing so, she mentioned the Jedi library on Exis Station, which Tionne then inquired about, and the device projected a hologram of the ancient library's former appearance. Lochett mentioned that the Mage Orloc was from Exis Station. Tionne was surprised and put down the holocron to question Lochett, deciding not to access Krimsan's holocron again until Skywalker returned, since the gatekeeper had mentioned that it was intended for the use of Jedi Masters. Instead, she placed both the holocron and Obi-Wan Kenobi's lightsaber in Skywalker's quarters.
Lochett, who aspired to become a Jedi but lacked Force-sensitivity, believed Krimsan's holocron could aid him in his quest. During the night, he snuck into Skywalker's empty quarters and attempted to access the holocron. Unable to do so, he decided to steal both Jedi artifacts and travel to Exis Station to see if the mysterious Orloc could teach him how to use the Force. To reach Exis Station, Lochett stole the Sunrider, a ship belonging to Jedi Master Ikrit. In the morning, his friends discovered that he and the Sunrider were missing. While they immediately suspected he had gone to Exis Station, the Jedi spent the rest of the day searching the grounds of the Praxeum for him. When Lochett did not turn up, Tionne, Ikrit, Solo, Veila, and R2-D2 traveled to Exis Station on Tionne's vessel, the Lore Seeker, to retrieve him.
Upon Uldir Lochett's arrival on Exis Station, he was captured by Ranats working for Orloc. They threw a sack over his head, injected him with a drug to render him unconscious, and carried him further into the station. The Ranats brought him to Orloc, who questioned him. Lochett then offered Orloc Krimsan's holocron and Obi-Wan Kenobi's lightsaber in exchange for teaching him magic. The Mage suspected a trap by the Jedi, but accepted Lochett as his student. When Orloc was given Krimsan's holocron in return, he unsuccessfully attempted to activate it. To disguise his failure, he claimed to Lochett that his own powers were far greater than the teachings of the Jedi. He told Lochett to concentrate on light, and the lights on the station dimmed. Encouraged by his apparent success, Lochett eagerly sought further instruction.
Soon, Lochett's friends arrived on the station to rescue him and retrieve the stolen Jedi artifacts. Anakin Solo and Tahiri Veila observed Lochett training with Orloc from an air duct grating high above the Mage and his pupil. However, their combined weight caused the pair to fall from the ceiling into the midst of Orloc and his Ranat and droid servants. Tionne and Ikrit jumped down from the ceiling to follow the children and telekinetically confiscated Krimsan's holocron and Kenobi's lightsaber. Furious, Orloc set his minions on the Jedi team, and the Jedi fled with the artifacts through a series of corridors into Orloc's control room. Orloc's forces engaged them there, and the Mage used his technological devices to unleash driving wind, steam jets, holographic enemies, and other hazards on the Jedi. During the fight, the Jedi lost possession of Krimsan's holocron.
Lochett joined the fight on the side of the Jedi and retrieved Krimsan's holocron from the floor. He tossed it to Veila, and it activated at her touch. The holocron projected an image of Asli Krimsan that filled the entire room. This helped Anakin Solo see past Orloc's holograms to reach the Mage. Solo then destroyed the devices on Orloc's costume that controlled most of his mechanical wonders. Using his last trick, Orloc produced a puff of smoke to distract the Jedi and escape. Krimsan's holocron was returned to the Jedi Praxeum, where it was later studied in depth by Tionne. Master Skywalker also studied the holocron for information on how Jedi could appear as spirits after death.
The first appearance of Asli Krimsan's holocron was in Junior Jedi Knights: Vader's Fortress, authored by Rebecca Moesta. Tommy Lee Edwards provided the first illustration of the holocron in Jedi vs. Sith: The Essential Guide to the Force. Its design appears to be consistent with a Jedi holocron model created for Attack of the Clones: The Visual Dictionary and resembles the Tedryn Holocron. Another illustration of the Visual Dictionary model is featured in The New Essential Guide to Weapons and Technology.
While the Star Wars: Junior Jedi Knights books suggest that Asli Krimsan and her holocron were contemporary to the abandoned Jedi library on Exis Station and thousands of years old, Jedi vs. Sith: The Essential Guide to the Force implies a more recent origin for Krimsan and identifies her solely as the holocron's maintainer. Specifically, the gatekeeper of the holocron comments on the Potentium (theorized in 132 BBY), and Dooku mentions that Asli Krimsan herself has asked him to speak. This discrepancy may represent a retcon of the holocron's established history.
