Anna nodded. She stretched the Blackfire into a thread, which gently arrived on the crystal pillar.
The witches subconsciously held their breaths. Then they saw some green smoke rising at the spot where the Blackfire touched the pillar. However, that was not the color of the smoke itself, but a reflection of the light of the Greenfire.
The Blackfire penetrated into the crystal.
"How is it?" Tilly asked.
"It's a bit difficult, but I can cut it open," Anna replied.
Suddenly, changes occurred in the Frozen Coffin. With a crisp clicking sound, a few cracks appeared around the area where the Blackfire penetrated. It looked as if the entire pillar was suddenly covered by cobwebs. Almost at the same time, Shavi held up a shield to protect all the witches.
