I have readed a lot of stories about the Rook.I investiged about him,and discovered that he normally attacked the Beta following the Alpha phase (after Alpha,there was the "First Beta" as I call it.This is "Second Beta", following the sudden rechange of Glitch to Second Beta).
My question is:do the Rook keep appearing?.How is he summoned?.The theory of the dice with Rook s' face is true?.
