Boss-Arena Idiocy: Given that Horrendous is a Mage Killer who hates wizards with a passion, one would expect his realm to be free of mana crystals.The only completely good person here is the airship captain aka Jandor, and also maybe Jack. Aldwyn and his conjurers at least aren't hateful, but they are complacent and passive and would prefer to watch the other two sides tear each other apart than get involved. If Jack is either a warrior or a wizard he'll be forced to slaughter the other side too, because they would rather let the world end than work with you.

Horvath and his wizards decided non-magic-users were sub-human, and as a warrior their shops won't serve you and you get arrested on trumped up charges as soon as you enter their city. Horrendous and his warriors decided that Magic is Evil and arrest wizards on sight as a wizard you discover these people are taken to a secret underground prison and tortured to death. Without necromancers to hate the warriors and wizards turned on each other.

Black-and-Grey Morality: Hecubah and her necromancers are totally evil and want to kill or enslave ( or kill AND enslave) everyone else in the world, but it's not like the rest of the world is much better.

The Atoner: That airship captain you keep running into is Jandor, looking to stop Hecubah' reign of terror after he saved her as a child.

Apathetic Citizens: Destroy their stuff, steal from their homes, and town citizens do nothing.

This can make the Ix Graveyard especially annoying as it's mostly occupied by huge amounts of urchins, who've probably stopped giving XP at this point but can still overwhelm you with weak projectile attacks.

Anti-Grinding: Weaker enemies stop giving XP if you're too far above them in power.

Hecubah, having somehow been 'purified' of her Necromancer traits, no longer has any memory of who she is, and it's strongly implied Jack is going to make her his girlfriend now.

Amnesiac Lover: Heavily implied in the wizards' ending.
