This mod from the Fall Further Plus Team does many things. See File Details for more info.
Author: Fall Further Plus Team
First and foremost, we have several new civilizations not featured in Fall From Heaven or Fall Further (The mod we are directly based on).
There are the Mechanos, a steam-punkish group that despise the gods for abandoning men, and view Magic as a disease that must be purged... They feature their own 'Religion', the Ordo Machinarum, which is in truth a worship of Power, Knowledge, and Progress.
There is the Legion of D'tesh, an undead Necromancer who cares so little for his follower's souls he willingly trades them to the would-be God of Death, Laroth, in return for assistance conquering all who oppose him. Unable to gain population normally, they instead take slaves from combat which can be sacrificed in cities.
Finally, there are the Frozen, a civilization revolving around the Arch-Angel of Ice, who is now attempting to take up the mantle of his fallen God. They are summoned into the game, offering a different playstyle from the norm.
As of now, the team is working on two additional civilizations of our own, rather than absorb those created by others.
We have reworked two civilizations extensively; The Malakim and the Doviello. The Malakim have gained far more affinity for their desert homeland, featuring Bedouin Camps and Camel Riders. The Doviello have become even more feral than before, with the ability to duel each other for dominance and spawn various Beasts over the course of the game.
