=== Spectral Types ===
For the Primary, roll 2d6. 

For each Companion, roll and add 1d6-1 to the Primary's number. 

''This generates a main sequence star; if the star later turns out to be a subgiant or giant, its spectral type will be changed. Don't roll for lone brown dwarfs.''

:2 — A-type or larger. <small>(You may choose to place an O or B star, supergiant, etc.; max. 1 per sector.)</small>
:3 — F-type
:4 — G-type
:5 — K-type
:6-13 — M-type
:14+ — L-type
