New theory to the Ruin Puzzle
The instance reset and randomization, though annoying, might be a clue on how it needs to be solved.
Lets start by organizing the geometries. There are 3 Rectangles with rows of obelisks(2 in G, 1 in E), 2 Triangles (E, B), 2 Stars (A and F ), and finally two little lines in D.
This is important because one of the messages decoded states things are linked with geometry. Culture 12
"This is truely fascinating data commander, as an engineer myself I have to admit I'm highly curious about the Guardians technology. It seems that the guardians had a particular fascination with geometric shapes, which they used to illustrate connections between themselves and the world around them. This predilection manifested itself in their technology as well - specifically their monolith network. With this data and the help of the galactic community we've partially mapped the monolith network, which formed the backbone of their communications technology, and discovered that they too are arranged in geometric patterns. Whilst this does not give us full access to the network, I believe it is the first step to unlocking the entire system and maybe more"
Emphasis on "the first step to unlocking the entire system and maybe more"
There are distinguished geometries on the map, and I believe they link pairs of obelisks. I've made a change to the map to illustrate.
Each of those groupings contains 2 Obelisks. Except for H, we'll get back to that one. These pairs are connected by geometries. When you scan one of the pairs, it gives you the data related to the other one. As in the objects needed to achieve the correct combination. When the puzzle sets up, it randomizes what combinations of objects are needed to get a message back. It also randomizes what the data types mean. Every new instance attributes five of the objects with Alpha, Beta, Delta, Gamma, Epsilon. Which means one wont work at all. You scan an obelisk and get Gamma, Epsilon. The sister obelisk needs the objects that correspond to that. That's why sometimes you get 1, and sometimes you get 2 data. Some obelisks only need 1 object, others 2. The puzzle then becomes a lot like an old school rogue like. The game is finding out which objects the data points to fast enough to unlock the sister obelisks. Use up all your tries and the instance (puzzle) needs to be reset.
Now, lets get back to group H with its lonely obelisk. Its been shown that a correct combination on an obelisks makes new ones show up. If the puzzle is done correctly, more obelisks start appearing. Creating a chain of scans and combinations. Eventually one will appear in group H and be a sister of the original.
