i'm lame so humor me, what's the vast glub? c:
The Vast Glub is a shock wave of psychic energy that was released by Feferi’s lusus before she died. It killed the entire troll race except for the Condesce and the eleven troll heroes who made it into the Medium before it was released. Karkat didn’t get Sollux into the Medium in time and he died. Feferi revived him afterwards.
