Chromie

Chromie, the Keeper of Time, is a Ranged Assassin Hero from the Warcraft universe. At first glance, Chromie appears to be an ordinary gnome. In truth, she is Chronormu, Bronze Dragon and a master of time. When it comes to temporal manipulation, there's no problem she can't solve... with some help from her future self, of course. Chromie is a long-range mage with high burst damage.
