Land-based journeys happen in the future and on alien worlds just as much as they do back home. The regions in Trials and Treasures are applicable to strange planets, whether the voidrunners be crossing Lofty Mountains or wading through an Unrelenting Marsh. Similarly, the journey activities available to characters in Trials and Treasures are relevant anywhere.

For encounters suited to a science-fiction setting, see  Sci-Fi Journey Encounters.

Mounts. A mount can only travel at gallop speed for 1 hour each day. Otherwise it travels at the fast/mounted pace.

Vehicles. Pre-industrial vehicles are unable to go faster than a slow pace, but motorized vehicles and more advanced vehicles move at the Vehicle pace in Table: Travel Pace.

Aircraft. Aircraft and starfighters move at the Aircraft pace in Table: Travel Pace.
