Navigating in the Xelorium is rather easy. The dimension is much smaller than Srambad. To navigate between the times Gonebyways (past), Present Day and Uncertain Future, you need two clocks. There is one clock moving you forward in time, Watch Running Fast (Gonebyways -> Present day -> Uncertain Future), and one moving you backwards in time, Watch Running Slow (Uncertain Future -> Present day -> Gonebyways).
These watches does not get destroyed when used, and can be traded between characters if you so desire. They can be used from anywhere in Xelorium, not just any particular map.
Please note that it's not possible to use the clocks from all positions on every map. Some positions might have obstables (holes, trees and so on) on the map you're trying to reach. If you can't use your clock, check if it's possible from other parts of the map before giving up. You will receive a message in the information channel if a jump is impossible.
These watches can be crafted. The recipes can be found below. Since watches aren't made by any regular profession, you're in luck: You don't even have to leave Xelorium to craft them. To find the special bench used for crafting them, go to the Xelorium Outpost at [1,6]. When you're there, enter the building, take the left door, then choose the door on the far left. Inside this room you will find a bench used to craft these watches.
