Portals create connections between worlds. Visit a Monolith to learn the location of a planets Portal. This will require a trade commodity matching the alien of the planet the portal is on.
Portals require glyphs to be powered before they can be used. Interact with the Portal terminal to power the glyphs.
Once active, a Portal can reveal the Glyph sequence for their planet. Other Travellers with this glyph sequence can enter it into their own portals and visit your planet.
The ability to input a Glyph must be earned. Enter caves and use the Scanner to locate the graves of fallen Travellers. Extract knowledge of glyphs from their logs.
Travellers may risk entering random Glyph
Sequences into a Portal, but the accuracy of such unattuned transport is not guaranteed.
