World of Warcraft 7.3 Sulama's mission is getting worse and worse. Where does the season change? I've been trapped for a long time

Both missions were in Sulamaa. Find Farodin, a walker in the NPC Valley in Meridale. The method of receiving tasks is as follows:

1. First, players come to Meridale, Sulamaa.

After the player comes here, he can see a night elf NPC, and then he can take over the task.

3. The increasingly serious crisis met Farodin, a valley walker, at the Temple of La in Fado. You can reach your destination by using the transmission point on Shar Island.

4. The change of seasons requires players to talk to the arcane artist Vatoi.
