Something I just realized about the dialogue between Anduin and Faerin that was posted yesterday:
Faerin says, in response to Anduin revealing he's friends with a dragon, that there are dragons in her homeland who appear to not be as friendly as the dragons we are used to. Presuming these dragons are descendants of the green dragon who flew through the storm, I wonder why these particular dragons aren't at least neutral like the ones we are used to? She (the dragon) was an imbued dragon iirc, as she spoke to Tyr about what was to the east (or west, unsure what direction it was); and the only aggressive imbued dragons we've met are basically corrupt or purposely antagonistic.
