Okay. So I'm going to go on a tinfoil rant here a bit.. Put on your hats.
Drew recently took down his lore guide. And he just recently put some back up. Go here to read some for yourself
http://www.drewwagar.com/elite-dangerous-saga/elite-dangerous-lore/
Anyway. He basically said that anything in these guides is going to be canon from this point on, but should not contain too many spoilers. Spoilers are different from hints. One of his first articles is based on the generation ships. Talking about them, he says that:
Some are into their 30th generation. Those that are still enroute are travelling in ‘normal’ space, at relativistic velocities.
Collectively these travellers are known as ‘the missing.’
Interestingly enough, if you ‘do the math’, you’ll discover that due to the relativistic speeds, time aboard the Generation ships will have been compressed for the occupants. A further observation results in the conclusion that many of the ships should be reaching their destinations around about now if you assume they were targeted at stars within 100 lightyears (which seems plausible for 24th century technology). The maximum distance they could realistically travel would be around a 1,000 lightyears (probably much less), so both the ships and the civilisation that emerged, if any did make it, should be easily reachable by today’s explorers.
So.. My current tinfoil theory is that we are indeed looking for the generation ships. Or at least one.
Option a.) What if they chose Merope/Pleiades as a destination and are nearing it now? The UA/UP could simply be probes sent out to determine a place for them to settle.
Option b.) They have already passed the Merope system on their way to another and have left behind waypoints for anyone following them so that they can find them.
The spectrogram may be either a.) a map of their destination or b.) a map to wherever they went past Merope. Maybe they got to Merope and found it an unsuitable system and moved on. They also may have bioengineered some form of alien life that they found somewhere to create the technology in the probe. Or they are not constrained by our AI laws and are using one to create new types of synthetic life.
Whoooole lot of tinfoil here. But this season was supposed to be about The Missing, and we have only found some of the more immediate parts of that. The generation ships have been hinted at for quite some time and we have found nothing in game yet about them. Ideas? How far off could this be?
