* CrowningMusicOfAwesome: A soundtrack as detailed as the original game, with music mostly taken from NoxArcana (used with permission) and Creator/CirqueDuSoleil.
* DesignatedHero: The game runs on BlackAndWhiteMorality, but many of the "Good" factions are AxCrazy and so devoted to the destruction of evil that they don't care who they kill in the process (or in the case of the Mercurians, actively encourage the death of good people so they can be reborn as Angels to defend the world).
** Which is rather possibly intentional, even the leaders branded as good are incredibly anti-heroic and such, emphazising the CrapsackWorld Erebus actually is.
* EpilepticTrees: Many, many examples regarding lore that hasn't been fully explored.
* EvilIsSexy: Faeryl Viconia and Flauros.
* GameBreaker: Without a doubt, Chalid Astrakein is one of these. The Religious Hero of the Empryrean, he possesses a spell, Piller of Fire, that turns enemy deathstacks into an absolute joke. Basically, every time he casts it (and he can cast it every turn) the largest stack within two tiles of him gets absolutely ''devastated''. It doesn't matter how many units are in there, they will all take tremendous damage, leaving them with only 20% of their health, and thus, 20% of their attack power. It can't outright ''kill'' them, but since losing health weakens their fighting power, the stack is easy pickings for your army.
* ThatOneBoss: Any enemy civ's HeroUnit would count, but the most notable ones among the barbarians are Orthus, a warlord who appears early in the game to terrorize and eliminate any unprepared players who happen to be nearby, and Acheron, a really nasty dragon who is supposed to be optional but may spawn right outside your borders. The most [[GoddamnedBats irritating]] HeroUnit is Loki, who can't be killed unless he is surrounded or in a city. This wouldn't be so bad except for the facts that he can enter enemy borders at will and flip cities without culture, such as all new cities unless you have a certain trait.
