There are six factions to be active in Albion, with a long history of conflicts between them:
The Royal Expeditionary Forces and the Heretics are at war, though this is more a case that the two groups will attack each other on sight rather than an organised attempt by one to wipe out the other.
The Disciples of Morgana and the Keepers of Albion are also at war and the fighting between the two groups over their northern territories is intensifying.
Some demons are allied or controlled by the Disciples of Morgana, others are independent. All of them are hostile when encountered.
The Undead are at war with everyone. To date they have never gathered in large numbers and show no interest in territory outside their own.
For hundreds of years, the Keepers of Albion were the dominant faction. Then the Heretics came, followed by the Royal Expeditionary Forces, and then the Colonists. This, coupled with the release of the Undead and the return of the Disciples of Morgana has put everything into flux. It is a time of great danger, and great opportunity!
