The underworld
The power of the abyss was so incredible that Darla lost a great amount of power to find it.
A glowing circle of purple light came into view afterward. "That is…. That is the abyss". She said, This was exactly the same thing she saw in her vision when she told her fellow Witches about the abyss for the first time. At that time, she also saw that it was in the possession of their first ever Queen [Ember].
"How do we use it then?". Mia asked.
"You can't. You don't know our history, but ever since our true blooded witch Queen made use of it, since then, no one has ever been able to use the abyss. Fortunately, I was given a privilege by the abyss to be able to use it". Darla replied to Mia.
"No. You can't use this Darla. You've lost half of your divine power. If you make use of this forbidden abyss, you might get killed immediately!". Hattie tried to talk her out of this, but it seems like Darla already made her choice.
