Notes on several setting topics are gathered on this page. Most of these offer direct insight into the setting, and give guidelines for both players and storytellers on how we view the setting.
From the forum thread Travel Times and Communication Speeds.
Star Wars is a fictional setting, which means travel often goes at the “speed of plot”, people arriving the time that the plot calls for. In general we follow this, but there are some guidelines regarding distance as well:
Hyperspace travel by ship takes 10 days per hex on the map, or about 10 lightyears per hour. This is an upper bound, not a lower limit - some ships may be slower. It is possible to go a bit faster, but not a lot.
The only exception to that is using hyperspace lanes. These significantly speed up travel times. The bozzy spine makes speeds go x10, so travel through hexes on the map along the bozzy spine takes one day per hex. Local hyperspace lanes, as provided by the Union, doubles speed, so travel through those hexes takes 5 days.
Communication is faster than using hyperspace to travel, but it is still limited.
In general, within a single hex, you may fairly presume real-time communications. It does not matter if it is between planets or systems or from one edge to the other. Communication between hexes is generally too slow to maintain a live stream. Instead, a message is sent out, and a message is received, as if by letter.
The exception is using existing Holonet Relays. These speed up communications and allow live conversations over extended distances, provided both sides are connected.
While it is not explicitly defined, you may presume your homeworld is hooked up to the Holonet of NPC Union members over the Bozzy Spine so you can communicate live with the Union government (or your own if you are present on Unity).
Holonet communication is limited to basic data such as text, speech and a simple hologram and subject to minor errors. Most sentients can deal with a mispronounced A or a glitchy picture, but computers don't like that. Surely you can send MP3s or a short video, but not large files or scientific data or secret plans, for example.
Any significant amounts of information cannot be transmitted but must instead be carried over by data-crystals.
Again, the exception is using Holonet Relays. These have focussed point-to-point links which have far higher bandwidths and can transport data on an industrial scale.
From the forum thread Cyborg
Cybernetics are cool, but they face limitations. In general, cybernetics integrates machines with the body, but it does not provide additional abilities beyond those a regular person would acquire using technology.
For example, you can use cybernetics to grant an individual cyborg the ability to fly, equivalent to using a jetpack, but you are limited in the duration of your flight by the amount of fuel available and thus cannot maintain flight as long as a winged individual would.
Likewise, you can use cybernetics to communicate with others electronically, equivalent to using a telephone. However, it requires at least some moments of concentration to dial up the right person, and you can only communicate with a small number of people simultaneously and you cannot broadcast widely (at least not without being excessively obnoxious to everyone, who will be interrupted by the call). Moreover it only works when network is available.
As a final example, cyborgs might be resistant to space, but only to the equivalent level of someone in a space suit - they can spring leaks, get shot, etc.
The limitation also applies to combinations. You can only have a limited number of applications in a single body. All in all, someone with a regular piece of technology will be equivalent in ability to a cyborg. The power of the cyborg lies in that the technology is part of their body rather than a loose device.
