The Seraphim Knights are the revived form of the pre-Calamity Rune Knights.
Started by Quince Haven with the goal of becoming both the military and police force of Alakitasia, these are mages who seek to serve and protect. Highly trained and proficient in the use of Magic, they aim to maintain the peace in each of Alakitasia's settlements. At the present, they get requests from varying towns and villages in the form of missions to bring criminals to justice.
The Seraphim Knights are a militant agency directly affiliated with Odin's Spear, sharing the guild's goals to bring about law and order to the post-Calamity world.
To become a Seraphim Knight (SK), you basically just have to be a good-aligned character who wants to join an organisation that specialises in taking down criminals. I'll make specific modded missions for the SK.
Captain: Quince Haven II
Second in Command: open
Recruit: Mint Everett-Bailey
When you join you are automatically a recruit. To become a soldier, just complete a SK-specific mission.
