Can two objects, ever truly be identical? Identical twins, born from the same womb, are still separated by the fact that one was born before the other.

Their mind, thoughts, aspirations and dreams will never completely be equal, they can never be completely the same. Two twin swords, held together, both expertly forged to be exact replicas of one another.

To the untrained, and even the most trained of eyes, they are exactly the same in almost every way. But the star dust from which provided the chemical compounds of each of the swords would undoubtedly be different. The friction of each upon the ground are both jagged in different ways, no matter how hard one tries, the twin swords would never be identical. They will always be separated, in ways beyond anyone's ability to rectify.
