A dark fantasy scenario for VideoGame/{{Civilization}} IV, which was included in the ''Beyond the Sword'' expansion pack.

The world is in an [[ExactlyWhatItSaysOnTheTin ice age]], and has been since Mulcarn, god of winter, took over the world after the BalanceBetweenGoodAndEvil was upset when the fire goddess Bhall [[FallenAngel fell from heaven]]. An immortal archmage, Kylorin, has created a civilization, known as the Amurites in a valley sheltered from Mulcarn's blizzards. As Kylorin, the player must fight Mulcarn's Illian followers and their Doviello allies to reclaim the three pieces of the Godslayer, a weapon which has the power to slay Mulcarn.

This is a prequel to VideoGame/FallFromHeaven.

This mod provides examples of:
* AfterTheEnd: Before Mulcarn entered the material world, there were many thriving civilizations. All of them except the Illians were destroyed.
* AllThereInTheManual: Much of the backstory for the characters and world can only be discovered by reading the in-game Civilopedia.
* AnticlimaxBoss: [[TheDragon Drifa, the White Dragon]] is supposed to be impossible to kill. He isn't.
** Impossible to kill, no. Hard to kill, heck yes. [[spoiler: Mulcarn]], though, is a pretty easy boss; [[spoiler: most of the game instead focuses on finding the [[SwordOfPlotAdvancement God]][[InfinityPlusOneSword slayer]]]].
* AnIcePerson: The entire Illian civilization.
* ArbitraryHeadcountLimit: You can only have one hero unit active at a time.
* AxCrazy: The Doviello. Actually, it's [[CrapsackWorld pretty normal in this age]].
* BlackAndGreyMorality: The Amurites are the only people in the mod who aren't outright evil, and according to [[VideoGame/FallFromHeaven Fall From Heaven 2]] they are rather amoral in the following age.
* DeathWorld: If you don't freeze to death, you'll probably starve or get killed by monsters or barbarians.
* DidYouJustPunchOutCthulhu: The object of the game is to kill a god. [[spoiler: It's pretty easy. Getting the Godslayer is what's difficult.]]
* DualWielding: Belenus, Caerbulin, and the Illian axemen.
* EvilIsDeathlyCold: Mulcarn and his servants, obviously, but if you know of about the universe of VideoGame/FallFromHeaven they're not the worst [[EldritchAbomination thing]] [[TheLegionsOfHell out]] [[UltimateEvil there]].
* FallenAngel: Bhall, the fire goddess, whose fall enabled Mulcarn to take over the world.
* GoodWeaponEvilWeapon: Played straight, as the regular Amurite infantry use swords, while the Illians and Doviello use [[AnAxeToGrind axes]].
** The [[AllThereInTheManual Civilopedia]] says that Mulcarn keeps ancient macemen frozen in his throne room.
* HeelFaceTurn: The Doviello will surrender to you if you weaken them enough.
* HiddenElfVillage: [[VideoGame/FallFromHeaven Fall From Heaven 2]] reveals that the [[OurDwarvesAreDifferent dwarves]] were unaffected by the age of ice.
* InfantImmortality: Averted in a subtle and a direct way. The direct way is obvious with Children of Kyorlin as a game unit. Creating infirmaries boosts the creation rate of said children by as much as the capital. Up until one was built there was [[FridgeHorror implict quite high infant morality.]]
* KillItWithFire: The only attack spell in the game is Fireball.
* LowFantasy: The game's gritty setting has some elements of this.
* MundaneUtility: In the backstory, the Godslayer was used in ordinary wars.
* NinjaPirateZombieRobot: Malus of the five, an [[TheUndead undead]] {{pirate}} fulfills two of these.
* ReligionOfEvil: The White hand, which is dedicated to worshiping Mulcarn.
* SapientSteed: Kylorin can get one if an unlikely sidequest happens.
* ShroudedInMyth : Amurites in the later age insist they were chosen to join for being worthy in some way. The real reason? He had no other option who didn't collaborate with Mulcarn.
* TheSmurfettePrinciple: Epona is the only female character in the game.
* StormingTheCastle: If the [[NorseMythology Frost Giants]] are giving you too much trouble, you can storm their castle of Utgard.
* SwordOfPlotAdvancement: Finding the Godslayer is your focus for most of the game.
* TheDragon: Drifa, the White Dragon, is a literal example.
** Technically, Taranis the Unchanging is Mulcarns actual dragon, as he is Mulcarns archangel. However, he is trapped on an island, so he never actually appears.
* WarriorPrince: Kylorin's children can become powerful warriors and spellcasters.
* WeCannotGoOnWithoutYou: Once Kylorin appears as a unit, you had better keep him alive or you'll lose the game.
* WorldHalfEmpty: Erebus, even more than [[VideoGame/FallFromHeaven usual]].
* ZergRush: The Illians, Doviello, and Barbarians will throw seemingly endless waves of units at you early in the game.
