Fragmented fresco

Introduction

"The beetle looks at you, ignorant of the reasons that caused you to disturb its sleep. It, however, shows no signs of hostility towards you. So you look at the old parchment representing a fresco you saw on a wall, south of here. Obviously, finding all the pieces will answer a question, but which one?"

Cunclusion

"You managed to collect all the pieces to reproduce the fresco located south of this spot. However, a red brick was drawn on your version and you are fairly certain it was not on the wall. You would be well advised to go back and take a look."
