History Manhwa / CavalierOfTheAbyss

** [[spoiler:Xix, whose entire village was razed and childhood friend killed at Nex's orders, has a death wish against Nex and is completely thunderstruck when he discovers that he is Nex and Serin's son. This after Nex defeats, tortures, and nearly kills him. He was actually resurrected by Siana.]]
** [[spoiler:Siana, childhood friend of Xix and a necromancer, been born as the child between a woman(implied to be Serin in Chapter 66) and an unknown Night Clan member that Caladbolg/Jae Hoon is convince is Nex/Jae Hyuk. Xix thought she died when his village was destroyed, but her body was taken by Caladbolg and he had his forces work to save her. She reappears later in the present aligned with Caladbolg, who she calls "uncle" and he calls her his niece. Her current body is not really hers.]]

* TheLawOfConservationOfDetail: Used a great deal in this series.
** The fact that a undead can't survive without their heart [[spoiler: Xix is captured and later watches his own heart destroyed early in the series, leading to what should have been Skoll being let lose and his death. Instead he turns up fine seemingly with his heart intact. It isn't until dozens of chapters later that we found out it is because he had two hearts since becoming a Undead. ]]

** Most major characters from the prequel have made appearances here, more or less along the same lines, but [[spoiler: Seon]] has flipped allegiances to Caladbolg following another one of Nex's (apparently many) massacres.

Cavalier of the Abyss is the sequel series to ''Manhwa/ImmortalRegis'' by creator Ga On-Bi. The story brings in a new protagonist, the rash revenge-driven undead named Xix against the brutal Immortal Regis of Chaos, Nex, who was once known as [[FallenHero Jae Hyuk]]. Meanwhile [[DeadlyDecadentCourt various factions of the Regis' court]] and outside forces seem to be attempting to moves around the same time as Xix attempts assassination of Nex.

** [[spoiler:Siana, childhood friend of Xix and a skilled necromancer, been born as the child between a woman(implied to be Serin in Chapter 66) and an unknown Night Clan member. Xix thought she died when his village was destroyed, but she reappears later aligned with Caladbolg, who she calls "uncle" and he confirms she is his niece. Her current body is not really hers.]]

* ItsTheOnlyWayToBeSure: Whenever [[KnightTemplar Nex]] finds Night Clan Corruption in a town, he has the inhabitants slaughtered; no exceptions. Somewhat justified as TheCorrution spreads like a wildfire if it's not stamped out in a hurry.

** Nex is somewhere between a [[SlidingScaleOfAntiHeroes Type IV and Type V]], as he's a cold, bitter, ruthless, jaded tyrant but he's also trying to prevent [[BigBad Caladbolg]] and followers from bringing ruin to ''both'' worlds.

** Serin is locked in a box, heavily sedated, and subjected to an eternal nightmare, punishment for a major betrayal that has yet to come to light. Nex, however, cannot bring himself to killing her. Which of Nex's children she did or did not give birth to while running away from him are a major plot point.

** [[spoiler:Xix, whose entire village was razed and childhood friend killed at Nex's orders, has a death wish against Nex and is completely thunderstruck when he discovers that he is Nex and Serin's son. This after Nex defeats, tortures, and nearly kills him.]]
** [[spoiler:Siana, childhood friend of Xix and a skilled necromancer, been born as the child between a woman and an unknown Night Clan member. Xix thought she died when his village was destroyed, but she reappears later aligned with Caladbolg, who she calls "uncle" and he confirms she is his niece. Her current body is not really hers.]]

* EtTuBrute: Serin apparently betrayed Nex in the past; the scar on his back came from when she literally back-stabbed him. [[spoiler: Just to twist the knife further, she was also pregnant with his child at the time.]]

* [[spoiler: LukeIAmYourFather: Xix and Nex are related by blood, and it is confirmed that Xix is actually the long lost child of Jae Hyuk and Serin. Neither Xix or Nex are particularly happy about this.]]

* BerserkButton: Nex displays varying degrees of tolerance for the usual antics that go along with politics and court intrigue (i.e. plots, deceit, back-room deals, etc). Openly rebel against him however, and all bets are off; He '''will''' kill you, and anyone else who tries to stop him. [[spoiler: Thus-far, the only person to press this button and survive is Xix, and only because the palace was attacked right as Nex was about to decapitate him. That Xix may actually be his long lost son may explain Xix's continued existence.]]

** [[spoiler:Xix, whose entire village was razed and childhood friend killed at Nex's orders, has a death wish against Nex and is completely thunderstruck when he discovers that he is likely to be Nex and Serin's son. This after Nex defeats, tortures, and nearly kills him.]]
** [[spoiler:Siana, childhood friend of Xix and a skilled necromancer. Also very likely to be one of Nex's children, even more so than Xix. Xix thought she died when his village was destroyed, but she reappears later aligned with Caladbolg, who she calls "uncle" and he confirms she is his niece. Her current body is not really hers.]]

* [[spoiler: LukeIAmYourFather: Xix and Nex are somehow related by blood, and it is heavily implied that Xix is actually the long lost child of Jae Hyuk and Serin. Neither Xix or Nex are particularly happy about this.]]

* EvilFormerFriend: Thanks to the backstory this comes a lot with Nex.

* BerserkButton: Nex displays varying degrees of tolerance for the usual antics that go along with politics and court intrigue (i.e. plots, deceit, back-room deals, etc). Openly rebel against him however, and all bets are off; He '''will''' kill you, and anyone else who tries to stop him. [[spoiler: Thus-far, the only person to press this button and survive is Xix, and only because the palace was attacked right as Nex was about to decapitate him.]]

* TrollingCreator: A ''lot'' of chain yanking, considering the series did essentially 360 from where it had stood at the end of Immortal Regis. The author likes to drop hints and clues in every which direction, but never giving a clear answer; this is partially why the manhwa is so confusing for the first 20 or so chapters.

* [[spoiler: LukeIAmYourFather: Xix and Nex are somehow related by blood, and it is heavily implied that Xix is actually the long lost child of Jae Hyuk and Serin. Neither Xix or Nex are particularly happy about this.]]

* WeUsedToBeFriends: Seon and Nex. [[spoiler:One joined the Night Clan because the other wiped out his entire race.]]

** Nex is a cold, jaded tyrant with a sadistic side who ''mascaras'' villages on a regular bases, doesn't even blink when Xix threatens to kill his son's fiance, and has Serin, previously his one true love, tied up in an ''eternal nightmare''.

** Most major characters from the prequel have made appearances here, more or less along the same lines, but Seon has flipped allegiances to Caladbolg following another one of Nex's (apparently many) massacres.
** Iffrita is notable as well: although she never appeared in the previous work, an extended flashback from two years after ''Immortal Regis'' shows how she wasn't always an utter manipulative bitch.

Cavalier of the Abyss is the sequel series to ''Manhwa/ImmortalRegis'', the new protagonist a rash revenge-driven undead named Xix. The new Regis of Chaos is a bitter Jae Hyuk, now called Nex. What happened in the past to make Chaos and Nex this way, who created Xix, and what is the enroaching darkness?

And then Caladbolg is unsealed...

* DeliberatelyCuteChild: Caladbolg.

* [[spoiler: LukeIAmYourFather: It's recently been reveled that Xix and Nex are somehow related by blood, and it is heavily implied that Xix is actually the long lost child of Jae Hyuk and Serin. Neither Xix or Nex are particularly happy about this.]]

** Ouroboros, also known as Just, is the son of Nex and Serin, and is a ManipulativeBastard who takes sadistic pleasure in tormenting Ninurta.

*** FallenHero

** Nex is a jaded megalomaniac of a world ruler who burns villages for fun, doesn't even blink when Xix threatens to kill his son's fiance, and has Serin, previously his one true love, tied up in an ''eternal nightmare''.

** [[WellDoneSonGuy Ninurta Noah]], the prince and purportedly the son of Nex and Iffrita, although Nex is said to have accepted him without actually checking if this is true; it's implied he's actually the son of the queen and Mikhail Noah, as he bears little resemblance to his father. [[spoiler:Nex is not fond of him, and when he is captured by a dragon-bourn Siana, Nex orders his men to fire at him and declares him a traitor. Currently a guest of Caladbolg on Earth.]]

[[spoiler:* KissingCousins: When incest actually did become canon, with Iffrita and Mikhail Noah.]]

* VillainousFriendship The series has quite a few great example, but in particular... [[spoiler:the friendship between Caladbolg, Siana and Ninurta is notable.]]

** Caladbolg, supposed God of Chaos [[spoiler:who [[PuppeteerParasite possesses and continues to identify]] as Jae-Hoon, Nex's little brother. Due to this, a large plot point is how there's no clear distinction between both personalities. Later it is shown he has grown up healthy and comparatively sane against all odds, and has adopted Siana, who he confirms is his niece. That he comes off as [[AffablyEvil far more compassionate]] than Nex is funny, since he is the BigBad.]]

** [[spoiler:Siana, childhood friend of Xix and a skilled necromancer. Also very likely to be one of Nex's children, even more so than Xix. Xix thought she died when his village was destroyed, but she reappears later aligned with Caladbolg, who she calls "uncle". It's implied her current body is not really hers.]]

* DeliberatelyCuteChild: Miya uses this to come extent, but... [[spoiler: Caladbolg takes the cake on this one.]]
