For a civilization that has achieved movement by Warping or Teleportation, there's really no point traveling in more primitive ways. Movement has a different meaning for them.. and it impacts the way their world looks and functions. There should be no roads or bridges.. Wait a minute, my planets abound in broken chunks of what looks like roads and bridges and platforms. Eh well. Gameplay.
We could assume a few things tho. One, this Alien civilization needed a lot of ways to move around. Warping was a shortcut, maybe often busy, but not all roads have to be shortcuts. A 10 minutes walk, or fly, or bubble [which is maybe what you do when you float in a bubble like a magical princess..], doesn't require teleportation. Two, what appears as broken chunks of roads and bridges to us.. maybe had different functionality in reality. And maybe they looked quite differently, ages ago, when they were in use.
I will change Traveller to Traveler, in US spelling, which I normally use. For consistency.
And.. dialogue output! I've extended the Raven dialogue box to a lot more than just Raven. It's much clearer now what does what and the meaning of most things.
