What would happen if everything you knew was forgotten.
Amnesia struck you like a train, the headaches, the sorrow, the emptiness.
Everything from the start of your birth would be a burning building, crashing down. Once stood a mighty structure protecting everything inside, and then in the blink of an eye, that structure has burned down. The remnants of the structure gets destroyed and then a new building is put. Everyone forgets what was inside the last building, what it looked like, every historical moment inside that building has become vanquished.
