Classic Injection system quest not available On Guard in Stonetalon

[blink]

Used injection system to abandon not needed quests, and do required prequests. Character is Warlock level 24. Guide sent to talk to Kaela Shadowspear to accept On Guard in Stonetalon, NPC does not offer any quests. Seems to be missing prerequisite.

Guide:Alliance Stonetalon Mountains (22-23), step 2.

[blink]

Missing prereq seems to be part 1 given by Sentinel Thenysil in Ashenville.

You were not following the guide from level 1? Did you abandon quests manually or did you have the guide viewer abandon quests?
