World Beyond Dreams

In this world, every living being is born with a powerful substance called mana. Mana can create spells or weapons, or even boost physical attributes like strengh and speed. The Agency was founded to prevent widespread anarchy, so they made factions. Factions can be made by anyone and they act like a team. When a faction war is started it teleports both factions to a pocket dimension for a fight, it teleports the entire faction even if some members aren't there, so it's always the full faction. A faction war ends when a leader dies. You are currently at a tavern when a small faction of bandits walks in.
