There were hundreds of Low-rank Fire Spirits for Vaan to choose from, but he wasn't sure which one would be the most suited for him.
Some Fire Spirits took on various forms of aerial creatures like eagles, hawks, crows, and phoenixes. Others took on the forms of ground creatures like salamanders, tigers, and cats.
There were many forms of Fire Spirits.
But regardless of whether they were aerial or ground Fire Spirits, they were all capable of flight, which didn't surprise Vaan.
They were Fire Spirits, after all.
"If you're interested in entering a contract with this person, come closer to him. He will choose one among you to be his spirit companion," Flamewing instructed, thinking it would help narrow down the options for Vaan to decide.
Naturally, the Fire Spirits were all interested.
However, even if they were all Low-rank Fire Spirits, they also have their differences in character and express different levels of eagerness.
