The War Campaign continues in Patch 8.1.5 with Lady Jaina sending you to Freehold to learn more about Lady Ashvane joining forces with Sylvanas.
Then, Valeera delivers a message to Jaina from Baine. Baine brings Derek Proudmoore as a undead to Jaina at Theramore.
Opinion: This might be another hint at cross-faction undead characters and/or cross-faction races, as I have speculated for some time. Derek asked Jaina if he could return home to Boralus. She doesn’t seem too oppose the idea much. Asked for time to think about it.
