'Darkness' comes from the fallen 'Bright', containing domains such as corruption, darkness, and decay.
It's perfectly normal for curses to be inclined towards the domain of 'Darkness'.
After some consideration, Aaron took out his tools, preparing to create a magical item.
As a 'forgemaster', not only had his speed of absorbing the spirituality of the 'Bright' greatly increased, but he could also understand the meaning of the 'Bright' creations during the forging process.
Even while forging some materials, he could extract the pure spirituality of the 'Bright' from them.
Aaron called this 'skimming the cream', and if other craftsmen knew about it, they would be insanely envious.
After all, for those craftsmen, forging is a laborious task, let alone gaining the benefits of pure spirituality from it.
'With each magical item forged, the 'forgemaster' becomes more powerful... until the end of the third substance.'
