In a certain episode with Darth Maul and Savage Oppress, Darth Sidious comes and kills Savage and also overpowers Maul himself. The Clone Wars then switches to other subjects, and they don't show Maul again until Ahsoka finds him in Mandalore.
What happened to Maul during this time? Is there any canon story around this time? (I'm assuming this is not in any movie or series.)
