I don’t expect logic from her, however given that she wanted to depict or highlight enmity between the two clans, she could have done so without maligning the eagles, she could have shown them as enemies but noble creatures. Unless the Garuda clan she is referring to belongs to some rogue family.
Exactly, what I think. Cause she has never distorted the natural enmity with nevla (Mongoose) or Mor(peacock), so I think here this clan of Cheels are not the Garudas that we have read in myths. They are roguish thugs. Like Garudas are a very divine class of species that protected the Amrit and did not attack Nagas unless provoked and vice versa. So I think EK has shown the other type here.
