Tonight I learned this otherwise forgettable villain from the Sunwell Trilogy is a rare mob in the Dragon Isles:

I always likes when Blizzard brings in old, forgotten little characters, be it from quests or external media. This rare could have been anyone, but by making it someone who we’ve already seen before, even if it was 17 years ago in a comic that most have forgotten, it makes the world feel a bit more coherent and lived in.
Legion in particular was really good about this, I feel, like Valorn from Curse of the Worgen, Meryl from Med’an’s comic, or Revel from Dark Riders showing up in artifact quests. Dragonflight doing it too makes me a bit more optimistic.
