The golden flames did not hurt Adrian but activated he magic circle and his entire soul is suddenly pulled into the heart of the ley lines. His brain would have been overloaded if not for the fact that he had the Fire Elementum as a guide. If he used the World Resonance Magic Circle without the Fire Elementum then his head would have literally turned to mush because of the information that would have flooded into him.
At the very heart of the ley lines, Adrian is seen covered in golden flames as five elemental worlds could be seen around him. This is what Adrian feared the most as items of great power tend to mutate depending on their surroundings. The fact that the five other elementums have awakened and created areas for them to reside is the reason why the difficulty is at the level of a Transcendent.
