How to answer the Warcraft mission and escape from Kuska Pool?

The World of Warcraft mission escaped from Kuska Pool and was connected on the map: Vilda, the healer of Kamen Rider Shadow Moon Valley NPC (coordinates: 54.2,21.2).

At the bottom of Kuska Pool, Vilda, the earth healer, was surrounded by water polo, and the task was triggered automatically. Vilda, the earth healer, was escorted out of Kuska Pool, and then he went to the curse altar west of Gourdain's hand, and asked Torlock, the earth healer, to call me back.
