Character Biography
"The wind god Hwanung appeared in our lands today, and tried to convince the wind god Hanuman to stop his assault. This proves the wind gods are not the evil we thought they were originally. Hwanung is trying to contain the power Hanuman has, and to limit the damage he is doing.
I talked at great length with Hwanung at his request. He alone cannot bring Hanuman to his senses; he alone is not powerful enough. The only way he will be able to stop Hanuman is with the help of the third wind god, Tangun.
We must continue to assist the second wind god, Hwanung and work to release the final wind god Tangun. Once the third god is free we will be able to stop Hanuman, and save our cities.
I also have also talked to Hwanung about the powers of the winds, and the possibility of us using the power of the winds to defeat our enemies, such as the Sonhi. He assured me that once Hanuman had been defeated he would be discussing it with us.
I look forward to being able to access this great power. Citizens, we need to move quickly, and free the god Tangun as soon as we can."
