* CompleteMonster: The HighPriest Drwc. He convinces Rhiannon to become Arawn's sacrifice by threatening to ''chop off a little girl's fingers''. There's also that whole "I want to summon a demon king to destroy the world so I can rule what's left" thing.
* GeniusBonus: Barring the obvious [[KingArthur Arthur, Morgan]], and [[Creator/GaiusJuliusCaesar Gaius]], a lot of names and characters [[{{Mabinogion}} harken back to Welsh Mythology]] like Arawn, Rhiannon, Epona, Annwn, Pwyll, etc. ''Especially'' clever is the [[OnlyTheChosenMayWield Sword in the Stone]] being named 'Durnwyn' rather than the [[PublicDomainArtifact generic Excalibur]]. Taliesin is named after a poet who supposedly lived during the time of KingArthur and wrote a bunch of poems about him.
** Myrddin is more of an {{Expy}} of [[spoiler:Greek Titan Prometheus]] and has nothing in common with his Welsh namesake. The villains feel like a Gnostic Demiurge committee, being tasked by an aloof deity to create the world but failing at making it `perfect`... and are not happy about it.
* FanPreferredCouple: There are a lot of Arthur x Octavia shippers possibly because their [[DistaffCounterpart Distaff Counterparts]] to each other (eg. Both are skill swordsmen, kind to children, lost a family member when they were younger, a leader who cares for their troops and grew to hate and later respecting each other.).
* HoYay: Arawn, to both his mentor Pwyll and his apprentice Arthur. To a lesser extent, Decimus towards Gaius via SubordinateExcuse. One one hand, deep camaraderie and eternal loyalty; on the other... somewhere between [[spoiler:Arawn and Pwyll's nigh-instant HeterosexualLifePartners status]] and [[spoiler:Arawn hallucinating Pwyll before he resolves into Arthur and spurs Arawn to ''stop dying'']]...
** FoeYay: Octavia and [[spoiler:Lidia]].
** LesYay: Though merely [[HeterosexualLifePartners really good friends]] in the game, that friendship necklace Octavia gave Morgan in the anime might make one think otherwise. And the holding hands, and Octavia's revealing FoeYay...
* {{Narm}}: The English version of the original game's theme plays at certain points in the story - usually those where you would ''not'' want to be distracted by its questionable quality.
** The English dub of the anime is pretty good, but the Gael characters have Irish accents that range from subtle, nuanced, and believable to MAGICALLY DELICIOUS.
* NoExportForYou: Not the anime series thankfully, but the game probably won't be released in the US.
* WhatTheHellCastingAgency: Creator/GregAyres as Rathy, [[spoiler:except [[SamusIsAGirl Rathy is a girl]]]].
