1. It is revealed that Legacy is mostly flashback/vision sequences (Jay dreaming of his Storm Fighter, Kai and Zane recreating their memory), with the only exceptions being the mini episode with Cole and his driller and the master class episode. Therefore, Legacy is canon, and the monastery murals are canon.

2. Season 8 already confirms that Misako found Wu, therefore, it is impossible that Cyrus Borg could have located Wu, as the show canonically states that Misako found him (Watch "Dread on Arrival" for reference).

3. Lord Garmadon states that only an Oni can defeat another Oni, which means there would be no point going back in time to retrieve weapons that are made of the Dragon's power. Besides, there are only two episodes left, and that clearly is not enough time for a time travel sub plot.

4. Since the Legacy sets are all reimaginings of past events, The Overlord very well may be a set exclusive. I have very high doubts that they would bring the Overlord back when they have an even greater threat that has existed long before the Overlord's time (that being the Oni Omega).
