There were three cracks on the magic mirror.
The first crack came from its first owner, the queen.
She was a powerful witch but very generous and cultured. Facing this talkative magic mirror, she hadn't smashed it to pieces.
The mark she left also caused the magic mirror to develop a psychological shadow when faced with the question of 'who is the fairest woman in the world.'
The second crack was formed when it went through numerous changes and arrived in a strange world, where it was sealed in a treasure vault. Time passed like this for a long time.
Until a man wearing a black cloak appeared, seemingly to plunder the treasure vault.
He discovered the magic mirror and was quite interested in asking it to reveal the entity he worshipped.
And so, the not-so-young magic mirror was cruelly rubbed against the ground by reality.
It also learned that there were invisible existences in this world.
