In Terraldia, classes are the ordering system applied specifically to Outworlders. These classes, from E to S, measure the observed demand and mastery difficulty of an Outworlder's cursion. They do not measure strength, a distinction that was misunderstood from the beginning and continues to be.
S-Class Outworlders carry cursions of the most demanding kind. This is the class of specialization. The connection required is absolute, bound to a concept so specific that only the person who summoned it can fully understand what it asks. Power at this level comes from a depth of focus that amounts to a private knowing no one else has access to. The mastery is difficult precisely because it is singular. Those who reach it carry weapons unlike any others, precise in their particularity, nearly impossible to counter.
A-Class carries a different weight. These Outworlders excel at drawing out the full extent of what their cursion already holds. They push toward the outer limit of what the weapon carries rather than working within the most specialized concept. Their range makes them useful across a wide spread of circumstances.
B-Class holds the balance between offense and defense in roughly equal measure, a steady output that adapts rather than committing to one extreme. Reliable in conditions that shift.
C-Class is built on directed control. Command over aspects of the surrounding or of circumstances, not raw output but precision and authority over forces or elements. Where finesse is required over force, the C-Class Outworlder carries authority.
D-Class moves quickly and with precise execution. Speed and exact response rather than overwhelming power. These are fighters who react to rapidly shifting conditions, whose gifts are in the reflexes and the timing.
E-Class is the most common. Their cursions ask the least in terms of mastery, which makes them adaptable across the widest range of situations. Simplicity in use allows them to persist where more demanding weapons would exhaust their bearers. The world tends to underestimate them. Their adaptability and the absence of constant strain means they endure in conditions where others collapse.
