Lind had witnessed the aftermath of beast tides in his mortal realm. The Floating Isles really could not have them as the islands were too small or isolated to be caught off guard.
Further, the islands had been divided up so much there was a stark separation of beast and non-beast powers.
Beast tides in the mortal realm could be devastating to any power. The Lotus Empire had lost the Western District in total a few million years ago from what he had learned.
The ones he had witnessed were in the Heavenly Maiden Sect lands. They flattened forests and damaged villages. People died but formations could help mitigate them.
The cause was usually a manifested aether beast claiming territory from the existing beasts. A manifested beast had incredible power as the salamander he had fought on the Fortune Way.
Thus it was a bit random for it to happen in settled lands.
