Howling Fjord

[peeonflowers]

Do you have to go there at any point during the alliance guide or can I quest there till 70 than start the alliance guide.

[Gudleif]

After Borean Tundre, the guide goes to Howling Fjord and do most of the quests there.
If you want to stay sync with the guide, wait until 70 before going to Northrend.
