Despite the immense distance, Arthur could sense the dense creation law energy radiating from that location. That was enough location confirmation.
But what caught his attention next wasn't just that single point of origin. As he focused, he realized that the same creation-based cosmic energy signature permeated the entire realm around him.
It only took him a second to form a conjecture, and he asked aloud,
"Lostvayne, that Seed Engine is meant to terraform a planet, right?"
[Yes, Master,] the sword replied. [It's MEANT to terraform a planet.]
Lostvayne's emphasis on the word 'meant' was enough for Arthur to know the sword had detected and realised what he had.
The Seed Engine hadn't just terraformed the planet it was placed on. It had gradually extended its influence over thousands of years, reshaping the entire dimensional space around it.
Before either of them could comment further, Celestia chimed in.
