There are two more sites. And the key to find them has to be there and maybe not obvious now but it will be obvious when we know of it.
Yesterday i just grabbed my ship and started flying on the durection of he main ramp till i went around the planet and roughly back at the ruins... but i may have screwed up. No luck.
The shape of the site itself should be a key to find the rest. Remember how the guardians like to add information hidden in the glyphs. Maybe we should treat this site as a glyph itself.
I am almost sure that the other 2 sites are on this moon. Why put 1 museum in 3 diferent systems. Put the 3 museums on the same one.
Im sure they are aranged on a perfect triangle but im no mathematician, and its hard to locate ruins from orbit.
Anyone good with numbers? I have his idea. The 3 sites should construct an equilateral triangle (repeated a lot in the game) an equilateral triangle on a sphere big enough so that the angles are 90 degrees each... having he coordinates of one of said sites... wich would be the coordinates of the second and third. Using the main ramp of the first site as direction to find the second one.
Food for thougts. Thanks guys
