[[WMG:The [[LightNovel/TheFamiliarOfZero mages and familiars of Halkeginia]] were [[TheChosenMany chosen]] to save the world of [[VideoGame/DragonNest Lagendia]].]]
If you think about it, these [=ZnT=] characters have similarities with these [=DN=] characters:

* Saito - Sword Master
* [[PowerOfTheVoid Louise]] - [[GravityMaster Chaos]] [[TimeMaster Mage]] / [[TeleportersAndTransporters Majesty]]
* Tiffania - Archer (YMMV on this, but OurElvesAreDifferent in Lagendia...)
* Julio - The Cleric Class -> Priest Class (The outfit matches!)
* Kirche - [[PlayingWithFire Pyromancer]] / [[KillItWithFire Saleana]]
* Tabitha - [[AnIcePerson Ice Witch]] / [[KillItWithIce Elestra]]

[[Tropers/{{Judasmartel}} This troper]] thought about it when he named his [=PC=] after Louise, and after studying the game, it came to his mind that the PC's name does fit her after all, what with the Chaos Mage having greater control over the PowerOfTheVoid than the other Sorceress sub-classes. [[spoiler:And it gets better when it was revealed in the [=LN=]s that Louise CAN Teleport, something the [=DN=] Sorceress can do.]] Then it snowballed from there.

[[WMG:The tink's family]]
Crazy theory: In the future, Argenta & Velskud settle their differences and end up married, and the tinkerer/academic is their adopted daughter.
* So far... jossed, but it could still happen [[spoiler:if she finds a way to give herself a normal human lifespan.]]

[[WMG:The Black Knight is eventually going to be a boss.]]
Considering the player character keeps getting stronger, it's only a matter of time. And when you defeat him the first time he'll transform into his dragon form and fight you a second time.
* Both jossed and confirmed. While you ''do'' fight him as a boss, you never fight him in the Black Dragon form, as he loses the ability to do that later in the story, and he pulls a HeelFaceTurn as well.
