There was a clear depth in the ways that the sky crow elder was able to use the wind mana around. Besides the fact that his feathers were white rather than the sky blue most likely due to the randomness of albino beings, there were other differences too.
It was clear that the chief of the sky crows had been in more than just a few battles in his life. There were sports on his body missing feathers entirely and his beak was cracked, but not broken entirely. Otherwise, there was a staff leaving nearby his seat.
The staff itself was made of the same wind affinity wood used in the homes of every sky crow that the party had seen. Further, there were also wind elemental runes carved along it. Where it was more potent was the fact that there was what seemed to be some sort of refined gem placed in each inch long section of the staff. Making it store and produce very potent wind mana that also somehow seemed to be bonded with the sky crow chief.
