When Theron saw the magic circle appear above them, he thought he was hallucinating. And when he saw the lower body parts of two massive figures making their way out of the magic circle, he thought he had finally lost it.
It wasn't until the three elders and Monryck raised their heads and saw the same thing he did, that was when he knew that he wasn't hallucinating nor had he lost it.
This happened around the time Orun saw the explosion caused by Cerberus mindlessly rampaging about with its fire breath.
The two circles hovering above them are from Orun activating his elemental creation ability to bring about Efreet and Salamander's descension.
Their heavy bodies fell out of the magic circle and crashed down to the ground, releasing a temporary shockwave.
"What the hell are those now". Monryck asked with a panicked voice.
Despite their working together, they have yet to have the necessary capacity to contend against Cerberus.
