Bane Lightsaber
Some slides in the original post were videos; still frames are shown here.
Darth Bane is legendary for his role in instituting the Rule of Two amongst the Sith, where there is only a Master and an Apprentice. Beyond that, his lightsaber skills were also just as legendary, wielding a curved hilt in Form V Djem So that focuses on lightsaber duelling.
This exhibit showcases a Darth Bane lightsaber manufactured by @official_saberforge @saber_forge and customised and installed by @black_sun_sabers . The hilt is heavily weathered representing the battle damage and scarring by the numerous lightsaber battles that Darth Bane was involved in. It also features a marble crystal chamber from @nobi_wan4life , powered by a Proffie board for light and sound.
