It' Canon!!! In the new SW Rebels episodes, Yoda is sending Ezra, Ahsoka and Kenan to Malachor to get answers how to beat Vader and the Inquisitors or how not to beat them Cant wait the next episode
Yea this is very exciting news! Although Malachor was brought up in Clone Wars. Also, Kylo Ren's lightsaber is suppose to be a design dates back to the event called "Great Scourge of Malachor".
