Go to droknars a dwarf gives you the quest there.



(The Dwarf gives you the quest that leads you to the people that gives the quest)

the "dwarf" is named vanyi, she is near the xunlai agents.
she gives you a quest to do hero's journey where you have to go to hero auidiance destiny's gorge and seeker's passage.
there are some ghosts there that give you profession changing quests. once you have done them any of the four ghosts can change the second profession

Ranger and Monk are at Seeker's Passage.
Warrior and Mesmer are at Destiny's Gorge.
Elementalist and Necromancer are at Heroes' Audience.
