It would have been better if they were drow

KOTLC REACT WITH KEEPER CREW by FastReaderBadWriter
I know there are a lot of these, but I wanted to try it out. Also it might sometimes slightly turn more story-ish so sorry! Rated T just to be safe and I might have ships and stuff but really I'm pretty sure this could be K because there will be no actual bad language or anything. I might include a little bit of Percy Jackson stuff but not much. If I do it's only in the beginning.
