The Trouble with Taivan

For those attempting to do this quest on a second character (as this will naturally be available on your first leveled character, since you must do the campaign at some point):

You MUST complete the ENTIRE campaign in Ohn'ahran Plains in order to access this quest, and to therefore get the Sojourner achievement via that character. I had completed every side quest in the zone except this one, and couldn't find out how to access it at all, until I realized that it was because I hadn't completed the campaign. I would check back after each advancement of the campaign, to no avail. Only after I completed the very last campaign quest for the zone, 'Renewal of Vows,' was this accessible to me.

I do believe this to be a bug, and one I've submitted to Blizzard, as an alt shouldn't be required to complete the campaign quests to access side quests for an achievement (though one should probably still complete the campaign for the speedy renown).

1. Click on [npc=196665], the giant beast right next to the quest giver, to brush him:

/way #2023 61.2 40.0 Taivan

2. Then click the pelt right across from him (https://imgur.com/a/Rs7jDDh), and put it on Taivan.

3. Talk to Taivan.

4. Turn in at /way #2023 71.4 49.6 Hunter Jadar

P.S. Subsequent quests in this quest chain give reputation in addition to XP.

this quest requires you to have completed all the campaign quests in the zone for some reason
