It's possible you might be misremembering the book or have mixed it up with another story. There are other fantasy books that feature creatures with similar names. To help identify what you're looking for, could you provide more context?
For instance:
* What are the characteristics of these creatures? (e.g., size, appearance, abilities)
* What is their role in the story? (e.g., allies, enemies, mythical beings)
* Can you remember any specific scenes or chapters where these creatures appear?
With more details, I might be able to help you identify the creatures you're thinking of.
