Because of the World Voice, it was basically impossible for elemental creatures to conceal their own energy fluctuations. That was why Lushleaf Groot had made such a guess.

"The passage leading to the Tidal Realm is in the Fire Region. You will learn its exact location in the future." Angel paused. "I left a special mark in that passage.
