10 races were added in the battle for Azeroth expansion. Dubbed, "allied races," these races are allies the alliance and horde partnered with to strengthen their power. There are five races for each faction and all of them have different starting zones.
Almost all allied races start in their capital city, and are given a quest to report to their faction's emissary in their faction capital city and are told to meet with Chromie. Chromie is sitting on a hourglass a few steps away.
