Here's a challenge for anyone with a little time on their hands.
The glyphs on the Obelisks have 36 triangles that just happens to correspond to A - Z + 0 - 10.
Using https://ixalon.github.io/elitedangerous/ you can figure out the frequency.
Compare it to something like: http://imgur.com/a/quK4X (Alphabet Frequency Chart)
and you may be able to find a pattern.
Hopefully that should decrypt the "language" and tell us something.... maybe.
