Nailisi was emotional when she received the fully-restored Twelve Notes of Purgatory. The weapon was only second to her Gray Memory. After it had been fully restored, the dimensions in the Twelve Notes of Purgatory would be expanded to a terrifying extent. She had never heard of any other equipment that contained such a massive space.
The Twelve Notes of Purgatory formed a complex structure, which was bonded together by very tight links. Six of them were elemental purgatories while the other six were rule purgatories. The Grandmaster was upset with the demon's greed and took away the weapon's spirit, as a form of compensation to himself.
