Tharifas

Tharifas was a green dragon who, based on the presence of custom game data there, originally was to appear in 3rd chapter of the Night Elf campaign of Warcraft III: Reign of Chaos. He/she was related with a quest involving a dragon roost and some dragon whelps. However, this quest was removed from the game before it was released. As a result, the Tharifas unit is only used within the map data for the Night Elf interlude "The Last Guardian", with two copies flying over the Orc/Human battle but never quite within the visible camera frame.
