Since then I've switched to a draenei, so I've actually been ever more places. Just counting from when he woke up on Azuremyst Isle, I've been up and down Kalimdor, the Eastern Kingdoms, Northrend, Outland, the Elemental Planes of Deepholm, Skywall, the Abyssal Maw and the Firelands and now Pandaria, and soon I'll be going to another reality altogether. I've logged a lot of travel miles, I've been a lot of places. I often wonder what it's like when he goes back to the Exodar - does he ever consider settling down there? Or does his wanderlust motivate him to ever explore, ever head over the next hill, to see what's out there?
Okay, it may also be the loot. It's probably mostly the loot. But what about you? Why does your character keep going over the horizon, and how does she or he feel about where they came from?
