After Khadgar and Rhonin joined the Guardian Council, the senior Guardians spent far less time carrying out missions.
The Guardian Council had more time to devote to researching "arcane energy element fission" and the "Light-Energy Crystal."
After his interception mission ended, Khadgar did not linger in Menethil Harbor. He returned to the Guardian Temple on the Waning Glacier at once.
Research into charging the Light-Energy Crystal had reached its final stage. Through extensive data analysis, Khadgar finally found a unique energy structure that could activate it.
The sample behind this data came from the pure energy of the Heart of Azeroth.
The two kinds of energy were not identical, however, so Khadgar conducted nearly a hundred more experiments on that basis.
After changing into a pristine white protective lab suit and casting a powerful Protective Barrier on himself, Khadgar entered the charging hall.
"Master, have you made any progress?" Khadgar saw that his master had already opened an Astral Realm Gate, feeding the chaotic, complex energy into three towering Lightforging Crystal spires according to procedure.
Lightforging Crystals were energy-storage devices. This Draenei technology, steeped in history, was not outdated in the slightest. On the contrary, it was highly advanced.
Back when Khadgar was on Draenor, he had often seen Draenei engineers find traces of earlier technology in ancient texts and later developments, then recreate it.
Khadgar had always held back a sarcastic remark about that: What a way to develop technology-through archaeology. Civilizations are supposed to grow stronger as they advance, but yours just keeps getting weaker.
After directing the energy flow into the crystal Khadgar had made, Medivh nodded. "There are no problems with the connection, but the resonance between crystals produces different reactions depending on the amount and nature of the energy. That is something I cannot help
