Ice Pear City was the viscount's fiefdom, and Snow Pear Castle was his fortress.
And Steel Dyke City was Earl's domain, with the fortress named Little Riverheart Castle. The Earl was called Deborah Yuhua Stone, known as the River-Cleaving Swordsaint, who was said to have once sliced through the Roaring River with a single sword stroke. He was the nephew of Marquis Nuta Dimaria Yuhua Stone, but not the landlord of Yevich.
The Clear Water Sword Saint was a follower of Marquis Nuta.
When the Coral Island Knights arrived at Little Riverheart Castle, Earl William Lee immediately felt the difficulty, "No wonder it's called Little Riverheart Castle, this is clearly a fortress on a river isle. The difficulty of seizing this castle is too high, especially with those four large stone bridges traversing the river, it's like being a live target during the Knight Order's charge."
