Northguard can generate defensive forcefields made of plasma. The fields are circular, semitransparent, and vary in size from a small buckler to a large riot shield. The fields are produced through concentrated effort and disperse when they are no longer needed. Northguard determines the size of the field by drawing an arc in the air with his right arm. However, a field can be summoned without the movement. High-velocity projectiles such as bullets disintegrate on impact. Objects moving at lower velocities, such as thrown weapons, are deflected.
