What Once Was (Touhou Project)

Cover is temporary and not really Reimu focused

"What this area once was... was Gensokyo" was what they say. Nearly everything is gone from Gensokyo, all that was left was the still standing Eientei, some of the Scarlet Devil Mansion, and the sealed underground. Not even the barrier is there, only very few inhabitants from Gensokyo itself, most underground, is left. What happened? Who's behind this? Most importantly, what once was in Gensokyo?
