Hex Signs and Wyrmholes Part 3

So, how do we set up a hyper Venn diagram map?

One way is to draw up a grid. I suggest we honor tradition with eight by ten measurement and 80 hexes or squares. I used that in square or hex format and went with a 1 in six chance of a star in each square or hex. This gives us about 10-15 worlds which should be plenty for a game. If you need 40 or so worlds then roll up three or four such subsectors.

A tip for rendering artists out there: create your grid and make it a group. That way when you  no longer need it you can delete it or hide it. I think W.I.N.G.S. works the same way. The stars shown have the minimum size 'brane for the dimmest stars. 
Once you have a grid and your stars positioned you start placing their membranes (or just 'branes). A star has a number of branes according to a die roll or assignment 1-3 one brane, 4-5 two, 6 three or four. generally speaking there is no more than one star with four or more branes in a subsector. Anymore would really scramble the branes of the other stars cutting them off from easy travel or 'pushing' them into their own subsectors (more on that in the next post).

A star with one brane is low mass and likely cool, and dim (M and some K stars). Stars with two branes run the gamut from midsize K to smaller G. A three membrane star is Sol class or larger. Four branes and we're talking Procyon and Sirius or larger.

Subsector flipped on its side -because it looks better! More accurately, rotated 90 degrees counterclockwise.
Membranes are generated by thermonuclear reactions of the stars and thrown out by forces that are analogous to light pressure. They are held in place by the star's gravity. In the case of a star no longer undergoing fusion, some might persist for a hundred million years or more.

Stars are much closer (nearly touching) in hyperspace. Nearby stars can pull on each other's branes distorting them or making them collapse. Where branes overlap, a ship with ftl can transition from one star to another.

Small, dim stars that are close to large bright stars may lie entirely within that star's branes. These are known as captive stars, and we will discuss them further in the next post (yeah, I'm milking this for -reasons.) Other stars may barely touch branes. On a hyperspace map the size of the overlap indicates how large a volume you can appear in. In the case of branes barely touching or kissing, the area will be very small perhaps a light second in radius or less.

How big are the branes? How big do you want them? This is double-talk (though hopefully entertaining and insightful double-talk). Pick radii to suit yourself. I went with about half a hexagon's width as radius separating each brane.

The star cluster above has a number of K stars that not only are prone to having planets with day and night and breathable atmospheres. Their medium sized branes let you fly from one end of the cluster to the other. The larger gold colored F-star is not positioned to take advantage of its larger branes.

Next we'll see how gravity affects this (working title 'Stupidity got us orbiting this neutron star, it ought to get us out of it!")
