So as i'm playing WoW, (being that i'm not a big lore person) I've noticed that the dragons (Halion, Deathwing, Alexstraza.. Etc..) Have either some kind of relationship, such as Deathwing and Nefarian, or some kind of conflict..
My question is..
Which dragons are related (or friends), and which of them have conflicts with each other?
