Ending

There are multiple possible endings to the Hellborn campaign depending on the player's actions and how much affinity they have gained with a certain faction.

In the Standard ending, the Borns will align themselves with either the Falkrick Alliance or the Western Expansion, complete the Civil War questline with their chosen faction, and then defeat the Hellfire invasion in the Final Battle of Valindor, where the Hellborn kills the Black Dragon and expels Algathon from existence. Northmarch is then rebuilt under the leadership of the faction that the Borns are sided with, thus leading to the reformed kingdoms matching the ideals and governing characteristics of the chosen faction.

Choosing the Falkrick Alliance results in the Northmarch kingdoms becoming more imperial and militaristic, with an emphasis on order and stability. Siding with the Western Expansion results in the Northmarch kingdoms becoming more socialist and liberal, with an emphasis on personal freedoms and the population carrying their own collective weight. Each reform has it's consequences; for example, the Falkrick Alliance limits the overall liberty of the population and imposes a stricter social hierarchy, while the Western Expansion has a weaker body of justice and government.

In the Hellfire Ending, the Borns are seduced by Algathon while fused with the Hellborn, and assist him in conquering all of Northmarch, thus allowing him to manifest in the mortal realm as a Black Dragon.

In the Bad ending, the Borns fail in their quest to stop the Hellfire invasion; they are either all killed, fail to summon the Hellborn, or fail to prevent the Black Dragon from being birthed from Mount Scorch.

In the Forged ending, the Borns side with the radical guerrilla faction and destabilize the Ten kingdoms, thus allowing for a single, unified kingdom known as Aeon to be established.

In the Unified ending, the hardest ending to achieve, the Borns are able to quell the Civil War between the Falkrick and the Western Expansion, thus leading to a fragile coalition that lasts long enough for the Northmarch legions to unite and defeat the Hellfire invasion. The fate of the truce is left unknown after Algathon is defeated, as achieving this ending will most likely kill the Borns due to them giving their life-force to preserve the Peace Gem, an artifact that allows its user to manifest a Divine Presence.
