A long time ago, in a galaxy called 'the Milky way' (it's our galaxy), people were really bored and started playing 'connect the dots' with the stars; and then they got high and made up stories for every single one of them.
Then, some time later, some people figured out that people were born on certain dates, and that somehow the sun was situated somewhere in the sky, being somewhere near one of 12 star signs the geniuses of yore thought up with at certain points in the year; which sometimes coincided with someone else's birthday. These people then went on and made funny little doodles, that make no sense, and have no correlation with any of the signs; and started associating these doodles with star signs To stop further over-complicate things here, because some other people found out that some planets did the same sort of tricks the sun did, science stepped in and found out being born in a particular month doesn't really make you a better person, and that we all differ because of phenotypes.
Regardless, the zodiac system still exists to this day, and even got an overhaul somewhere in the 30s to be somewhat more accurate for the current day starsky; you may, in fact, not be the birth-sign you thought you were; just look it up for yourself what you now are.
Then, in the 70s, a 13th sign was introduced (as well as a 14th, 'Cetus', removed in 1995), which reduced the now relocated Scorpio to around eight days, this sign is called 'Ophiuchus', the snake. This is you in this system. This never really caught on though (except in Japan), but is still included for completion's sake, and for those who like to work with some '13th symbol' stuff.
Anyway, to business; Included in the map are the 13 signs of the zodiac, reinterpreted as individual map components, though everything is in 'tools_nodraw' (I applied textures only for the screenshots). All of the signs are, counterclockwise, in chronological order (except for Ophiuchus, imagine it to be between Scorpio and Sagittarius, if you must).
