The galaxy map is defined by sectors which are further defined by sections. Cross-referencing the sectors and specifying the section allows the player and GM to determine an accurate and exact point of reference upon the game map. The map is referenced by reading across first, and then down to determine the sector, and then across and down again to determine the section number within the sector. Each sector is separated into 100 separate and distinct sections as shown below,
Planets and solar systems are not shown on the sector maps. Stars and other objects such as "weather" and "terrain" are shown on the sector maps. Fire On The Suns is a game and we have not tried to be scientifically accurate in our presentations of the stars, their planets, and the galaxy. Because the game is science fiction and takes place in a fictional universe, we have added some "features" that might not actually exist out there. Of course, with over a hundred billion known galaxies, each of which contains more than a hundred billion stars, anything is possible (and maybe even probable).
Each sector contains a rough average of 25- 35 objects (mostly stars) each.
Sector maps show the positions of stars represented by a letter designation which roughly corresponds to their spectral "type". The spectral types are as follows,
O
Blue spectral class;
Young, hot, brightly luminous stars
B
Blue-white spectral class; Stars which are slightly older than Type O
stars
A
White spectral class; Stars which are entering the Main Sequence of
stars
F Yellow-white
spectral class stars; Stars slightly younger than our own sun
(Sol)
G
Yellow spectral class stars; Stars approximately in the middle of the
Main Sequence like our sun
K
M Red spectral class stars; Stars which are older or have burned large portions of their nuclear fuel. Astronomers estimate that 50% or more of the stars in our galaxy are small, dim red stars of this class.
Players will begin with maps of their own areas of known space including surveys of the planetary systems that they have explored or colonized. All planets are described using a planet classification as follows,
M Habitable;
Earthlike planets with oxygen-nitrogen atmospheres, plenty of water, a nice
ecosystem, etc.
N Habitable;
Earthlike planets that are slightly more inhospitable than Class M planets, but
still fairly decent places to carve out a new home
P
Habitable; Planets that are on the verge of uncomfortable places to
live
R Habitable;
Uncomfortable or difficult places
S
Habitable; Very uncomfortable or difficult places
T Habitable;
Hostile environment planets. Not much water, lots of deserts, hostile lifeforms,
you name it
V Habitable;
Very hostile environment planets. Not the greatest place to live, but sometimes
it's worth it
X Habitable;
Extremely hostile environment planets. Not exactly the place you want to raise
your kids, but sometimes you just have no choice
Z Uninhabitable; Planets similar to Mercury, Venus, Pluto, Jupiter, Saturn, etc.
