TH quest chain begins in Azshara. Complete all the quests until Krazz gives you Twilight Skies, where you're directed to go to the Southern Rocketway Terminus. The first quests given in Az are finding the samophlange and a few others that pple have noted here; don't leave Azshara thinking the quests are unrelated to TH as many of us have done.
The Quest Ram is found in the Twilight Forest, in the Enchanted Forest biome. On a Magic Map, Enchanted Forest biomes look teal and the Quest Ram looks like a white upside-down 'U'. The Quest Ram only spawns in the Quest Grove, which is a rare spawn in itself.
