The words which Ethan uttered did not belong to the Atranese or any of Akarxia's currently known languages for that matter.
The words he spoke were from the language of the Gods. The forgotten language that was lost in the cycle of time. The exact one that was said to have been spoken by the Gods.
Ethan had no idea how he was able to speak those words subconsciously but he figured that it might be because of the combination of The Temple and his Ancestral Blessing.
Whatever it was, he did not care anyway because Ethan could feel it. He could feel the mysterious strength of his blessing coursing through his veins. The experience was very magical indeed.
The bluish-white particles that represented the Elements of 'The Cold Family' of Elements consisting of Frost, Ice, and Snow immediately appeared around Ethan's feet.
