[[WMG: Psaro didn't know Alena was one of {{The Chosen One}}s.]]
He was never after her at all -- it was the King he was after all along. The King's gift [[DreamingOfThingsToCome of sometimes seeing visions in his dreams]] threatened his plans, so he moved to take care of him. It was just a coincidence that Alena happened to be outside Zamoksva at the time, and a lucky break for her that the monsters moved against the castle during the Endor tournament... probably on the advice of Psaro's most powerful soldiers, like Aamon. If they hadn't moved right then, Psaro would have been there, and the final fight would have gone... poorly for her.
* Alternatively, Alena would've killed him right there at the Tournament.

[[WMG: Psaro's KarmaHoudini status was allowed because it would break the Cycle of Evil Rulers.]]
Just like Estark was destined to come BackFromTheDead, Necrosaro would become a SealedEvilInACan even after you kill him, to be a threat to the world centuries in the future. Whether he deserved it or not, saving him and resurrecting his MoralityChain would nip this in the bud.

[[WMG: VideoGame/DragonQuestIV is a prequel to VideoGame/DragonQuestIII]]
After the defeat of Estark/Esturk and (P)(Necro)Saro, Nadiria/Evil World was populated by normal people and over time morphed into Alefgard. That's why it's still the "dark world" in III.

[[WMG: Chapter 6 is an alternate version of Chapter 5.]]
And thus, Psaro can stay dead after all the stuff he did. Preventing him from gaining any {{Karma Houdini}} status as long as the player never does Chapter 6 or gets far enough in it to bring Psaro back.

[[WMG:There is very little difference between humans and monsters.]]
The only difference is humans are monsters who've embraced a certain level of civilization. This why the supposedly human opponents at the tournament look like monsters. They are monsters, but have chosen to live like humans. This is also Healy's reason for wanting to join Ragnar. He wants to become a human by spending enough time around humans. Sounds crazy, but it works, as Healy is now human by Taloon's chapter.

[[WMG: Celia / Eliza was FakingTheDead]]
TheHero was told all their life they had to defeat Psaro BecauseDestinySaysSo. However, were the Hero to simply go out and find out how the Dragon God killed their father, their resolve might have been less. Celia / Eliza may have even tipped off Psaro's forces to the village location to [[DoomedHometown give the Hero a motive.]] Once it was all over, she comes out of hiding in a magic flash and says she came back to life.

[[WMG: Zenith resurrected Celia / Eliza with a Yggdrasil Flower]]
Yes, it normally only grows every 1000 years, but he had one in suspension. The Hero refusing to become a god in Zenithia shook the Dragon deeply. He started to question himself, especially his killing the Hero's father. This was the first step to making amends.
* This doubt would lead to him accepting a DeathOfPersonality in ''V''.
