Adegan crystals were a subset oflightsaber crystal commonly used byJedi as a main component of alightsaber. These rareForce-reactive stones were primarily found in theAdega system, though a fair amount of these crystals could also be found on the planetHalm. Other locations where Adegan crystals could be found includedMygeeto[2] and parts of theCularin asteroid belt.
The Force shared a special connection with Adegan crystals, and it was through their use that Jedi created a bond amongst themselves, the Force, and their weapon. This trait caused the Adegan crystals in a lightsaber to give off a weak Force signature that could be sensed by any Jedi.
Themephite andpontite variants of Adegan crystals, which produced the best lightsaber blades, were similar in structure toIlum crystals.[3] This caused some to use their names synonymously, though crystals fromIlum were much more common.[3] Ilum presented entire caves full of high-quality crystals, while Adegan crystals were rare even in their own system.[3] This made Ilum crystals the most common lightsaber crystals amongst the Jedi until theGreat Jedi Purge. MostPadawans underwent the ritual on construction of their first lightsaber at Ilum.
The vast majority of lightsaber crystals from Ilum were green or blue with rare instances of purple, and though they were not as connected to the Force like the Adegan crystals were, all of them had the special properties that made them ideal for a Jedi's weapon. When induced by resonant frequencies, the crystals emitted powerful bursts of light, and further components of a lightsaber harnessed this power into a rod-like beam.Obi-Wan Kenobi used an Adegan crystal inhis first lightsaber.
During theCold War, theSith Empire discovered a way to utilize Adegan crystals mined from Ilum to create a stealth armada.
After the execution ofOrder 66, theGalactic Empire banned possession of all crystals capable of use in a lightsaber.
Types of Adegan crystal[]
A cache of rare pontite crystals
Kathracite was the most common form of Adegan crystal, followed byrelacite anddanite. These crystals didn't focus energy as well as their rarer cousins, and thus were usually reserved for use in training sabers.
Mephite was a typical Adegan crystal used by the Jedi.
Pontite was the rarest and most powerful type of Adegan crystal. Nearly impossible to find, it resonated with a powerful aura that cooled both skin and temperament.[4]
Behind the scenes[]
The term "Adegan crystal" was created by writerTom Veitch in theDark Empireendnotes, as an alternative name for all naturally-formed lightsaber crystals, after the system in which they were most commonly found.[5] In revised endnotes, the broader term "Ilum crystal" was introduced as a generic name for all crystals, thus making the terms Adegan, Ilum and lightsaber crystal synonymous.[6] However, with the later introduction of a crystal-rich planet called Ilum intocontinuity,[7] an in-universe explanation was provided for the terms being used interchangably, namely that crystal variants from the Adegan system were so similar in structure to those from the planet Ilum, that theJedi took them to be the same at first.[3]
