In Travel mode you can walk inside the virtual 3D world using familiar first person view. As you walk through the landscape you will always be on top of the objects. That gives you ability to climb on the top of the towers and castles or walk over the river using a bridge. Alas,there is no BFG-2000 on any our maps Dragon Flight. This is similar to Traveler mode except you are higher above the ground and move much faster.
Rumors regarding getting bumps on the head because of very tall mountains are entirely false.
Just fly trough it. Select the time of day on your continent. Sun or moon creates dynamic illumination effects. Choose various weather patterns from the sunny day, to rainy weather or heavy snowfall. Observe only economics of your realm by leaving roads, cities and mineral layers or level all the mountains and observe flat-landed realm.
