Ronald Shows Up!

This part of the city was at the conjunction between the city area and the forest in the front. This side of the wall seemed to be hastily built, as Arthur realized seeing it from above the issues it had here.

The walls were supposed to follow a straight line parallel to the woods before they would arch at the distance to connect with the rear walls facing the mountains.

However the walls here were abruptly broken, to go inside midway, leaving behind more area to cover.

That made a huge part of the wall coming from the mountains exposed, so they had to connect both using an oblique line of walls. This was where the weak defensive spots appeared, and it seemed they didn't have enough time to complete this weakened wall.
