Hare Moon Effect
Contrary to what Elder Rancaladra thought, Elder Tilrith suspect a different thing.
'He's trying to gain something through this spell' She pondered, frowning as she reached out her hand, finding that the lightning inside the ground prickled her palm lightly. 'A Royal Black Prince is already bad enough, but he's also an Awakened'
Observing the lightning sparks, she frowned deeply.
Since Rex cast such a large-scale spell, there must be a clear reason for this.
Pausing for a moment, thinking deeply to decipher the purpose of this spell, her eyes eventually widened in revelation. 'Did he find out about Elder Noskear? No... he shouldn't know about it, at least not yet. If he did, then there's no need for this spell. So he must be checking because of his suspicion of me. It's a mistake to tag along Elder Rancaladra, his intuition is very sharp'
Elder Tilrith realized that the spell was a detection spell.
