This is the first meeting we see with Mok’tringar’s council. We also bring a former guild member, Cretus, in as a villain. Warcraft sometimes has a drama all it’s own when people leave; sometimes that drama becomes focused, like leaving, changing factions, AND joining the guild that fights your guild. That’s a lot of emotional investment! It also makes good fuel for a plot and so he has a special role to play… This is also the first hint we see of a “third faction” allied with the Legion, comprised of Horde and Alliance members.
