My goal was to finally get the meta as School of Hard Knocks is the only thing standing between me and a Violet Proto-drake. As of this writing, I still haven't, but I have time. And so do you, if you're reading this early enough. According to the in-game calendar, the event ends at 11 a.m. PDT. Though I'm not sure how that works. Does the Matron just vanish?
Regardless, what about you?
