There's announcing a build challenge and then there's announcing a build challenge with style. Ecclesiastes has just released the latest in a series of challenges over at Eurobricks featuring the on-going saga Guilds of Historica and he has done so with a bang! I personally would feel extremely intimidated to submit anything to this contest as my MOC would only hide in the proverbial and literal shadows of this amazing castle. Seriously, it is OK to sit, stare, and marvel at the scale of this beast. I won't tell, just clean up the drool when you are done.
