Please help. I just completed celestia and I got no quests telling me to talk to merle ambrose.. I talked to the storm professor but thats all he said...
According to Lydia Greyrose, there are minimal levels to most of the second arc worlds. Until you reach those levels, you won't be offered a quest.
World Quest Requirement Level Requirement
Celestia The Final Countdown (Dragonspyre) 44 Zafaria Through This Door (Celestia) 55 Avalon Through Glass Darkly (Zafaria) 65 Azteca A Great Storm Coming (Avalon) 75 Khrysalis Speaker for the Dead (Azteca) 85
In your case, you need to advance one level to level 55. I'd suggest finishing up a few side quests and even completing Grizzleheim and Wintertusk before you try Zafaria. When it was originally released, it was intended for wizards level 60 & above.
