Pre-release theories:
- Confirmed.
- Jossed. Douxie is confirmed to be the main protagonist of Wizards, but Steve will still have a major role.
- Wizards is supposed to be the big finale for Tales of Arcadia. Why would they devote that to mocking the pacing of a television show that is too mature for the intended demographic?
- All Hail King Julien: Exiled is a parody of Game of Thrones, and nobody complained.
- The Tales of Arcadia are all set in, well, Arcadia. There's a lot of overlay between the shows' cast (Steve, Eli, and others in 3Below for example). If this franchise really was conceived as a parody of Game of Thrones' pacing (which, again, doesn't sound like a worthwhile finale), wouldn't it be blatantly adding tons of characters?
Maybe the Amulet of Daylight itself was created as an attempt to recreate Excalibur's magic potential, that power slowly corrupting Arthur into something so overwhelmingly dangerous that it requires an Avengers-style team-up to stop. Or maybe the Amulet was made as a prototype that would eventually lead to Merlin forging Excalibur and it was too powerful and Merlin was forced to seal Arthur away when the power made him too much of a threat.
- Confirmed... In a way, rather than Arthur being corrupted by Excalibur, he's killed and resurrected by the Arcane Order into their next champion and is the final enemy to be directly fought.
Post-release theories:
While the franchise establishes that Wizards Live Longer, Gallahad was no wizard, so there was no explanation for why he was alive in the 21st century in the first episode.
While in the show they joke about their quest for the Grail when Gallahad and Lancelot are busy drinking, it is just as likely that the Holy Grail does exist and at some point after the Battle of Killahead Bridge he came upon the Holy Grail. Either that or Merlin has the Holy Grail in storage and allowed Gallahad to drink from it as part of one of his long-term plans, Gallahad being needed to carry out tasks or even look after Castle Camelot and its Magitek. This also could explain how Merlin, Douxie and Morgana lived for as long as they did without aging, Merlin allowing both of his apprentices to drink from it, the Arcane Order themselves being immortal because they are so steeped in magic they no longer count as human (if they ever were).
