Posted an updated sheet.  Lots of new info there.


EDIT:

And just for confirmation we agreed FTL is as follows right? (note I added some fluff)

[i]Superluminal, or faster than light, travel became possible upon discovery of the 'void' and the attainment of supernatural powers by human beings.  While the drive that allows a vessel to dip 'below space' and skip along the boundaries between our reality and the void in a sort of limbo is a purely mechanical device, it is impossible to navigate this halfway space without a supernatural element.  This is because the boundary between limbo and our space seems to weaken in the presence of specific gravitational field interactions, and as a result fluctuating 'star lanes' exist hopping from gravity well to gravity well and terminating at around the edge of the heliosphere of the average star.  These fluctuations seem to follow no physical laws and as a result only Vacare, sorcerers who can sense the void itself, are able plot a course along the star lanes.  Attempts to navigate the halfway space without Vacare have either resulted in a ship being ejected into the interstellar medium, far from any help, or into the void, where nobody knows [i]what[/i] happens to them.

Of course, trusting a Vacare can be difficult.  The invention of the cognition engine has, in a way, given the rich and powerful the option of cutting the sorcerers out for the first time.  It was found that the cloned brain of a Vacare, if left to grow in a natural span of time, could be interfaced with a ships system and used as a sort of navigational bio computer.  The process of making a cognition engine is far from perfect and occasionally a cloned brain will simply show no psychic potential, but to cut out the middle man?  Many purchase cognition engines for the security it gives them.

Then again, for the Vacare themselves there is another option.  A risky, foolish, insane option.  The most powerful of the sorcerers have debated the possibility of ignoring 'limbo' and plotting a course through the void itself.  No star lanes to worry about at all.  It is theorized that only an extremely maneuverable ship could make such a journey...  Under its own merits.  What is to be found in the void is hard to even theorize, but for a truly powerful, and wise, Vacare perhaps a quick zip through that plane would be possible.[/i]

In summary, 

-Edge to edge
-Vacare or Cognition engines to navigate starlanes.
-Spooky void
-Powerful Vacare could try and bypass starlanes by zipping through the void itself, taking the time to stay there would be suicide... Right?

To accommodate [@GreivousKhan] here it's said that entering the void itself is basically suicide unless you're a super Vacare and quick about it, but who knows what's out there?  Maybe something could lend a helping hand ;)


Tell me if that fluff needs adjustment, Khan, Flagg, Ozzy, Ploy, Googer, etc.
