A Kara is a steel or iron bracelet of Indian tradition, which can be used as a devastating melee weapon.
Originally a Kara was worn as an article of faith, but Karas became popular with many Indians regardless of their beliefs, both for their simple, decorative beauty, and as a symbol of unbreakable attachment and commitment to a cause.
Evie adopted Karas after being introduced to them by her Indian 'brothers', who historically used them as protective rings to guard their sword arms.
During her time among the Indian Assassins, Karas were most commonly used like brass knuckles in hand-to-hand combat.
