Wait for it

Zolan had immediately told Evie about their discovery and that Luc was already on the other side. He also mentioned about his theory on how they could only go across the barrier once – thus, the reason why Luc was still on the other side of the barrier and still did not return.

As the vampires expected, the princess refused to just stay back and watch the barrier helplessly. She had called on Zanya for some advice and discussed on the possibilities of light fae magic that could be used to destroy a powerful barrier. Zanya had already taught her all the spells she knew but despite Evie's tremendous power and magic, the barrier remained impregnable. All of them could only gaze disappointingly at the barrier which still stood strong against all attacks.

The light faes also tried to help. They even tried attacking the barrier all at once with their combined magic when it was gathered at its peak. But it was still a futile effort on their part.
