"I will give mind, body, and soul to the safety and betterment of the people. I swear no allegiance to any power, foreign or native, but to the domestic community of the civil peoples. Defeat will never be an option. By the sharpness of my blade and mind, by the forces of magic and strength of will, I am a humble guardian of this realm of Earth. I am a Spellblade."
-The Spellblade's Oath from Of Chivalry and Sacrifice by scholar K. Winter
On the continent of Eriani, there exists the Order of Knights, which consists of sub-factions like the Shattered Shield Brotherhood and the Red Banner. While these sub-factions belong to separate kingdoms with individual motives, the Order was established to ensure that, in the case of a continental emergency, they would unite as one.
Spellblades are officially an elite sub-faction of the Order of Knights, though they are much different in many ways. Spellblades are a more general unit, working all over the continent rather than for individual kingdoms. Instead of fighting wars, they do jobs like monster slaying, fugitive hunting, and assassinations.
(I'm planning to make this a free-roam roleplay. So I will play the setting, NPCs, monsters, etc. and players can travel around the world that I present them, doing jobs and living life. While players will primarily be Spellblades, I'll allow some to not be. Spellblades will often enlist the help of others like healers.)
