The void creature's speed may have reduced, but it was still very fast. Halfway through the distance, Zol exclaimed to his companions, "Mason!"
He called to Mason take action with him. He then stretched his right hand towards the void creature and applied his telekinetic force, attempting to hold him in place.
And that was the reason he called out to Mason. With his barrier magic, he could create a containment while he held the creature back.
This would create an opening where Charlotte and Evelyn could explore and bombard it with their attacks.
Zol applied the force and Mason chased after the creature and made hand gestures as if to seal something between his palms.
This gesture created a solid rectangular prison that encased the void creature. The combination of Zol and Mason's abilities quickly trapped the void creature.
