Darth Plagueis's lightsaber

A red-bladed lightsaber was constructed by the Sith Lord Darth Plagueis.

History
When he was a Sith Apprentice, the Muun Darth Plagueis constructed a red-bladed lightsaber, the design possibly based on his master's - the Bith Dark Lord of the Sith Darth Tenebrous. Plagueis wielded his lightsaber when he sparred or honed his lightsaber combat skills.

It is unknown when it was made or on what occasions Plagueis used it in, but it was definitly used in the Muun's Sith training. After Plagueis murdered Tenebrous on Bal'demnic in 67 BBY, his lightsaber continued to be in his possession, even at the time he trained Darth Sidious as his apprentice. Palpatine did not use Plagueis's lightsaber as a base design for his own. After Plagueis was killed in his sleep by Sidious, the lightsaber was presumably destroyed.
