Forgotten

Masters of deception, infiltration and sabotage, the arrival of the Forgotten among the factions of Auriga will change everything. From pillaging extractors to assassinating governors, the rules of conflict will never be the same again. The Forgotten don't gather and use Science. Yet, they can buyout technologies using Dust. They can also rely on their unit invisibility and Hero skills to better pillage and infiltrate other empires.

Lore
A nightmare out of history, the Forgotten are a faction that all others thought to be lost or dead.

Against their will they were forged into a tight society of violent and distrustful survivors, having spent the final years of the cataclysm alone on the surface of Auriga.

Now, as rifts in their society have led a splinter faction to declare its independence, the Forgotten are risking everything in the hopes that the other factions will accept them - or kneel before them.

Science Phobic
The Forgotten are completely unable to produce or use Science. While it is technically possible to see the normal Science output of tiles by hovering the mouse over a tile, the Science Phobic trait adds a modifier to tiles that reduces the Science output to zero; as a result, when founding a city or when the FIDSI output overlay is enabled, Science does not appear. Additionally, the Forgotten are unable to unlock Technologies or City Improvements that increase Science production, but those that increase Science production as a secondary effect - such as the Arts Council - are still available.

As a result of these effects, there are some resources within the game that become nearly useless to the Forgotten. While the Forgotten are unable produce Science Stockpiles, they can still acquire them via the Marketplace, Diplomacy, or the Science Stockpile Facility. They can also technically use Science Stockpiles acquired this way, but doing so will not provide any Science, so it is best to just sell Science Stockpiles on the Marketplace for some extra Dust. Similarly, the Moonleaf Luxury Resource - which provides +50%  and +10  to cities when used as a booster - is significantly less useful to the Forgotten than it is to other factions, so as long as the empire approval is decently high, Moonleaf should be sold on the Marketplace for extra Dust. The Haunts Minor Faction also becomes less useful to assimilate, as the empire will not benefit from the +5% per pacified village that is gained by assimilating them.

Because the Forgotten cannot generate Science, they do not unlock technologies by accruing Science over time as every other faction does. Instead, the Forgotten purchase new technologies instantly with Dust, which can be done either from the research section on the top left of the screen, or on the Research Screen. The cost to purchase a new technology is based on both the Era of the technology, as well as the number of other technologies that have been unlocked. With N being the number of technologies already unlocked, and A being a constant based on the Era of the technology, the cost to buy a technology is as follows:

Cost=A*(6+N+N^2)

With A for each Era being:

Heroes
Note: Base Attributes reflect the unit's attributes before bonuses from equipment or capacities.

All Forgotten heroes are able to wield Swords, Claymores, Axes, and Claws as weapons.

Quest Heroes
Due to the Hero-focused path of the Forgotten's faction quest, a number of quest-specific heroes appear over the course of the questline. The most notable one is Ziema Adya, who is received as a reward for completing the second chapter of the faction quest, and whose recovery is a central focus of the quest's story. The player also receives the heroes Sable Deceiver Napog Dauda, Skya Keeper Dabuo Ofosu, and Efalo Tegret leveled up to Level 8 as a reward for completing the eighth chapter of the faction quest.

There are also a few heroes that appear leading enemy armies during the questline who cannot be obtained through normal means in-game. These include the Vaulter hero Agi Kinztak, the Drakken hero Archivist Mukangung, and the Forgotten hero Arla Sabor, who will be shown below.

Ziema Adya
Ziema Adya is initially received as a reward for completing chapter 2 of the Forgotten faction quest, but a second version of her is received upon completing chapter 3. When received, this second version of Ziema, is at level 5 (regardless of whatever level the previous version was at), has 4 unspent skill points, and is equipped with Tier 1 Iron armor and the Swords Shadowbrand and Shadowbinder (regardless of what equipment the previous version had). Additionally, Shadowbrand and Shadowbinder are also unlocked to be equipped on other heroes upon completing Chapter 3.

Because of the fact that Ziema Adya's second form starts at Level 5, the base attributes listed for her will reflect that, but will not include the bonuses provided by capacities or equipment. Ziema Adya's first form's attributes follow the standards for the other heroes, reflecting attributes at Level 1 without any bonuses from capacities or equipment.

Arla Sabor
Arla Sabor appears leading an enemy army, the destruction of which will complete the final objective of Chapter 8 of the Forgotten faction quest, and cannot be obtained by normal means. Arla appears at Level 7 with a full set of Tier 1 Hyperium Armor, a Tier 1 Hyperium Claymore, a Tier 1 Hyperium Ring, and a Tier 2 Iron Ring. Because Arla only appears as an enemy and therefore cannot have her equipment changed, her listed attributes and capacities do include the bonuses gained from her equipment and level.

Faction Quest
''Frustrated by the insularity - and perhaps cowardice - of your people, you and two allies decided to leave and forge your own destiny. But your journey barely started before disaster struck, and your mission has turned to one of bloody revenge.''
