As we all know by now, all of the comics previously produced by Dark Horse are no longer considered "canon". However, it appears that one of the last comics they are producing, Star Wars: Darth Maul - Son of Dathomir, will actually be considered fully canon going forward. This series is based on what would have been further Clone Wars episodes detailing what happened to Darth Maul.

There is a Spoiler Review where you can get some further information on this comic, along with a few pages showing the interiors. So, have a look knowing that what's contained in this comic won't be suddenly brushed away when Marvel takes over the comic production
