Winter Spring Castle is the central castle of the Baron Grant, standing by the Winterspring River, at the southernmost end of Springs Town. It has a history of over a hundred years.
The castle is entirely constructed of grey rocks, with thick and solid city walls rising up to twenty-five meters. The wall is smooth with not a single gap visible. The moat surrounding the city wall connects to the Winterspring River. The pristine surface of the water glistens, with occasional jumping fishes and shrimps.
A large iron-clad oak drawbridge spans across the ten-meter-wide river. A few strong soldiers are stationed by the winch. Thus, at any time when the guards on the lookout tower raise an alarm, they can immediately raise the drawbridge.
