The Merfolk are mysterious dwellers of the ocean that were once human, but had succumbed to the Sunken Curse of being bitten by a Mermaid or Merman, turning half fish but still keep whats left of their humanity, but some are too far gone and became red eyed and evil that we haven't seen in the game yet, only models of what they would look like. Could this enemy perhaps be hinting we will get a Merfolk Tall Tale or event in the future? Continuing the Flameheart story or a completely new tale? It might as well have a new Sunken Curse cosmetic to look like a Mermaid or Merman.
We might also get more lore of the game about them if we get introduced to one of them as a new character (one of the cursed ones, or the species that were born as Merfolk) we can talk to, possibly at Mermaid's Hideaway in the pool of water to begin the tale.
