* {{Anvilicious}} - GAMBLING AND DISHONEST MONEYLENDING ARE VERY VERY BAD, we get it already, please put down the hammer Miz Rodda ma'am....
** We get undertones of a GreenAesop in the third series as well, with all the talk of respecting the land. ''[[AllThereInTheManual Secrets Of Deltora]]'' ups it even higher. However, in today's consumer society, it may be said that SomeAnvilsNeedToBeDropped.
* BigNameFan - There are currently three main people that seem to run the forums and write the best stories in the Fan Fiction world:
*** [[http://www.fanfiction.net/u/1288540/homesweethomicide13 homesweethomicide13]] is known for Barda/Doom slash.
*** [[http://www.fanfiction.net/u/1779519/ASongInMyHead ASongInMyHead]] is known for writing stories that fill in the blanks.
*** [[http://www.fanfiction.net/u/1743641/PlatinumGal PlatinumGal]] is known for some cute oneshots.
*** [[http://www.fanfiction.net/u/1127353/LadyLapisLazuli LadyLapisLazuli]] and [[http://www.fanfiction.net/u/689413/PurpleLight PurpleLight]] occasionally step in, as well.
* ClarkesThirdLaw - A fair amount of what the Shadow Lord does sounds more like our technology than magic. From the lights in the Gray Guard growth building, to the "sparking rods", to the reference to the power being cut, it's easy to conclude that he's using electricity, which the heroes have no way to distinguish from magic. Whether the generation of Gray Guards is magic, science, or a bit of each is hard to say.
* CrackPairing - Some of the fanfic pairings are terrifying: [[MayDecemberRomance Lief]]/[[HoYay Barda]], [[HoYay Lief/Dain]], [[LesYay Sharn]]/[[MayDecemberRomance Zeean]], [[InterspeciesRomance Jasmine/Filli]] and most surprising, yet most popular: [[HoYay Barda/Doom]].
* EarWorm - The anime song about Thaegan and her children.
* EnsembleDarkhorse: ''Doom.'' 1000 times Doom. He has got to be one of, if not the, most popular character in the fandom, for all that he doesn't get as much focus as Lief, Barda and Jasmine, at least not after the first series. He's even more popular than the main trio, and that's saying something.
** Sharn. She's not focused on much, but fans love her for her quick wit and her strength. And for the fact that she pushed Prandine from that palace tower window on the night the Shadow Lord invaded.
** Anna is also very popular, despite only appearing in the first part of ''The Forests of Silence'' and being dead for the majority of the series, majorly because of her willingness (along with Jarred) to give up her home and identity for the royal family and go live in a dangerous forest which probably haunted the dreams of everyone in Del while heavily pregnant and manage to ''survive'' there for seven whole years with a small child to look after.
* EsotericHappyEnding: Yay, the series ended, the belt was completed, the prisoners got freed from the Shadowlands, they've found dragons of all 7 tribes and woken them up, the land isn't dying anymore, everyone's getting married and having babies! They have new festivals and there are fireworks and trade is happening and everything turned out great! Except, hey, remember that guy, the Shadow Lord? The guy who we've been told for the entire series is ''obsessed'' with taking over Deltora, and who we've repeatedly been informed has an anger and a jealousy that makes waiting 1000 years the same as acting now? The one who has endless plots and plans and whose main character trait other than being evil seems to be an absolute refusal to give up on his goals? That guy? Yeah, he's still around. Moreover he still has 2 of his Ak-Baba to breed and refine further, his grade 3 Ols are perfected, his conversion project is perfected, and ''he knows what went wrong last time''. The series doesn't have a happy end where it tied up all of the knots and ensured a happily ever after - the only thing that all 15 books managed is to hit the reset button. Deltora was effectively restored to the way it was in Adin's time - now all the Shadow Lord has to do is sit back and wait again, until the Kings start to get careless. And once they do... well, like I said. The Shadow Lord knows what it did wrong, last time. It will make things even more impossible for round 2.
** Unless Deltora can pull a MugglesDoItBetter and develop, for example, gunpowder. They already have one-way glass...
** Though it that may not be the case in the anime. Where it pretty much states outright that the Shadow Lord's gone for good.
* FunnyAneurysmMoment: Doom insulting Jasmine's mother during the Rithmere Games. It's light and funny when you first read it, but it gets worse when you realise that [[spoiler: Doom was insulting his own wife.]]
* GermansLoveDavidHasselhoff: The translated novels were so popular in Japan that it received a manga, anime, and even DS game adaptation.
* HarsherInHindsight: After the gang is captured by the people of Plume in series 2, Jasmine sarcastically asks Glock if his talisman [[spoiler:part of which is actually the Pirran pipe]] will protect him from The Fear. [[spoiler: The Fear ends up crushing him to death (on the bright side, he deals the killing blow to the Fear single-handedly, and the Plumes and Jasmine come to honor him as a hero for his sacrifice).]]
** In ''Maze of the Beast'', Barda speaks to Doom about Doom's past, to which Doom gets subtly annoyed. At first it seems as if he's just being his usual JerkAss self, but when you think about it you realise that he's uncomfortable and stung by Barda's questions as [[spoiler: he doesn't have a past, at least not one which he can remember.]]
* MagnificentBastard: The Shadow Lord is an absolute master of both the XanatosGambit and the XanatosSpeedChess. His plans are simply brilliant and he is one hell of a {{Determinator}}, no matter how many times he's defeated, he'll always be ready with a new strategy
--> ''"I have many plans, plans within plans."''
* TheMole: Deltora under Shadow Lord rule in the first series is full of spies, but [[spoiler: Dain]] takes the cake, especially for being able to fool Doom.
** [[spoiler: Faith]] is this in the second series.
** [[spoiler: Paff]] in the third series.
** [[Trader Baron]] in the ''Three Doors'' trilogy.
* OfficialCouple: Lief/Jasmine, [[spoiler: Lindal/Barda]], [[spoiler: Marilen/Ranesh]].
** In ''The Three Doors'', there's Sonia/Rye, Dirk/Faene and Sholto/Annocki.
* TheOphelia: Jasmine [[AlternateCharacterInterpretation probably]] qualifies.
* PortmanteauCoupleName: Jarda, for Jarred/Barda.
* TheScrappy - Prin. Good god, 1000 times Prin.
** In-universe, the opal out of all the gems. Lief hates touching it, since it usually means impending NightmareFuel.
*** ReplacementScrappy: In-universe; Paff replacing Ranesh as Josef's assistant in the library. [[spoiler: Her apparent ineptitude helps her real goals go largely unnoticed until almost too late]].
* ShipTease: In ''Deltora Quest'', Lief/Jasmine is continuously teased before finally being confirmed at the end of ''Deltora Shadowlands''.
** In ''Star of Deltora'', there is Britta/Jantsy and Britta/[[spoiler: Sky]]. It's not clear at the moment which pairing will become an OfficialCouple.
* TheWoobie - Oh hey, Jasmine! Let's talk about your life. You grew up in a forest. When you were seven years old, your parents were taken away, presumably to be killed, and your home got burned down. You had to fend for yourself. When you were sixteen, two strangers invade the lifestyle that you made for yourself, and your dead mother's spirit made you leave your home to go on a quest with them. You had lots of trouble because you could barely read or write, and most people thought that you were mad. Then it turned out that the guy you kind of liked was [[spoiler:a servant of the Shadowlord, and not even human!]] Eventually you discovered that [[spoiler:your father is not really dead but all that he has been through has made him a completely different person]]. And then it turns out that the other guy you kind of liked was [[spoiler:the heir to the throne and became King]]. Later, you found out that you had a sister, Faith, in the Shadowlands. Another guy you kind of like [[spoiler: dies on the way to the Shadowlands]]. Oh, and Faith? It turned out that [[spoiler:she was not real, but a plot of the Shadowlord's to get the King into his realm. And the Shadow Lord says explicitly that you were never important in his eyes, just a pawn that could be used against Lief]].
** Jarred's life is just as bad, if not more bad. His father died when he was four years old, and he was basically alone in the world, save having Endon as a friend. He was mistrusted by Prandine and possibly King Alton (as the King threatened to send Jarred away if he ever broke the Rule). When his close friend Prince Endon becomes King, he realises that Endon and Deltora are in danger because of the Rule, and tries to warn Endon but is accused of attempted murder of the new king and is forced to flee for his life. He finds a home in the forge and marries Anna, the love of his life, who ends up dying horribly in the Shadowlands quite likely with Jarred watching. Anna's death (possibly) ends up completely breaking him, and he's never the same afterward. Then before he has a chance to properly grieve her he loses all his memories during a fight in the Shadow Arena, and returns to Deltora a completely different person.
** Endon. He spent most of his life believing that it was important to obey the Rule and grew up learning to be dutiful and obedient. Then he realised that by doing what he had been taught to do his entire life, he had accidentally led his kingdom straight into the Shadow Lord's hands. The realisation almost breaks him. Then there's how he lost both his parents when he was just fifteen or sixteen years of age and also lost his best friend at the same time.
** Britta all the way. She longed to be a trader since she was seven years old, but after her father's betrayal and disappearance that dream was denied to her. She, her mother and her sister were forced to go into hiding to avoid the people's scorn, and her mother became so paranoid toward anything to do with trading and the sailing life that she forbade Britta and Margareth to go to the harbor and see Captain Gripp, an old friend of theirs (and Britta's closest and only one until meeting Jantsy), effectively isolating Britta and making her feel bitter and longing for her old life and her old dream of trading. Britta most likely had no friends until Jantsy, and no one to share her love of trading with who would actually understand and support it. Her mother did everything to bar her from it, which only alienated and embittered her, and when Britta finally had a chance to achieve her dream she had to do it in secret lest her mother find out and be angry with her (and try to stop her). Then when she finally tells her mother of her good fortune, her mother screams at her and tells her to get out, saying words that can never be taken back, and quite possibly by doing so has disowned her. Then there's the prejudice the people seem to have toward Britta and her family (even though they are only Dare's innocent family), which makes it more difficult for Britta to participate in the competition lest she be rejected. And there's also Zoolah's hate toward her...
