Upon his surprise discovery of a kyber crystal in Lothal's secret Jedi Temple, Ezra Bridger built his own lightsaber. Using gear and materials gifted him by his friends, Ezra's lightsaber has a more utilitarian appearance than a typical Jedi weapon. It also has a hidden feature: Ezra built in a firing mechanism, allowing his lightsaber to shoot stun blasts.
Growing up on his own during the age of the Empire, Ezra Bridger relied on his street smarts -- and subconscious Force abilities -- to survive. He became a con artist and small-time thief, doing what he needed to get by on his home planet Lothal. But this reality also hardened Ezra, who by the time he was 14 years old, had little trust for anyone. That would change with his introduction to the Ghost crew, a small band of rebels fighting back against the Empire. Ezra came to believe in their cause, and saw that he could help change the galaxy for the better. And with the help of Kanan Jarrus, he began to learn the ways of the Jedi.
The standard ranged weapon of both military personnel and civilians in the galaxy, the blaster pistol fires cohesive bursts of light-based energy called bolts. Appearing in a variety of shapes and sizes and sometimes augmented for other functions, including acension guns that fire grappling hooks, blaster pistols deliver a wide range of damage capability. Many blaster pistols have stun settings that incapacitate a target, rather than inflicting physical damage. While blasters do deliver a searing concussive blast, they can be foiled by magnetic seals and deflector shields.
At the heart of every Jedi lightsaber is a kyber crystal found on several planets, most notably the icebound caves of Ilum. This crystal is attuned to the Force, and connected to a Jedi Knight on a deeply personal level. In this way, a lightsaber is an extension of a Jedi's Force awareness. Because Jedi let the Force guide their selection of the crystal, the vibration that the crystal creates in the lightsaber blade helps Jedi center themselves and find balance in the Force. In this way, a Jedi can center his or her attention beyond the distractions of combat. A lightsaber crystal is colorless until first attuned and connected to a Jedi -- at which times it glows either blue or green, or in some rare instances, another shade. From that point on, it retains that hue.
An ancient building hidden within the planet surface, the Lothal Jedi Temple was discovered by Padawan Ezra Bridger through a connection with the Force. Inside the Temple, he and his Master, Kanan Jarrus, gained new insights into themselves -- thanks to guidance from Yoda, communing from a distant world. There, Yoda gave Ezra a kyber crystal, allowing the boy to construct his first lightsaber.
A survivor of Order 66, Kanan Jarrus hid his Jedi identity from all but those closest to him. Carrying a lightsaber openly would be too dangerous in the age of the Empire, so he kept his Jedi weapon in disparate pieces on his belt. Kanan would assemble his lightsaber, which had a blue plasma blade, only when necessary.
