Rainforest Sect, a Third-Rate Sect, was formed by the merger of two major families, the Yu Family and the Lin Family.
Within the Rainforest Sect, there were two Sect Masters. One of them was the father of Yuchen, the Head of the Yu Family, Rain Mountain.
The other was the father of Lin Chan, the Lin Family Patriarch, Lin Hailong.
Among the Thirteen Families was the Lin Family. It was said that Lin Hailong of the Rainforest Sect had defected from the Lin Family. However, this was only a rumor, and its authenticity could not be confirmed, because given the power of the Lin Family, if they wanted to catch a defector, it would be effortless—let alone allowing Lin Hailong to establish a Third-Rate Sect.
The Lin Family and the Yu Family merged to become the Rainforest Sect, but over time, the relationship between the two became like fire and water, completely incompatible.
