Unlike the other races of light, fairies or fae are extremely secluded and don't really openly engage in the war as humans, elves, and dwarves do.
Instead, they guard only their own domains with a rather fierce demeanor.
The only reason in particular that they are even counted among the races of light is due to their beauty which humans and elves find so captivating that it is worthy of reverence.
It also helps that they have more of an aversion to fallen than other beings.
Fae are said to be so powerful that if they put their mind to it they could overturn the balance of the world with their numbers alone.
And whether or not that is rumor or fact, the fallen don't particularly want to find out so they avoid the domains of the fairies like a plague.
So needless to say, the fact that the fallen here had been led right smack into the waiting room of the fairy king himself was about as appealing as a sandpaper fleshlight.
