you know, it doesnt look 100% TEC.... It might just be the color throwing me off a bit... but it looks like it is very old. I wonder if the catch with Titans is that its like an artifact? or somehow involves them?
Maybe if you discover an artifact and do some research (higher-tier), you can discover the location of a damaged Titan ship, which you then bring to a capital factory (or maybe build some kind of new temp starbase around it) to repair and repurpose. That would take alot of work to get (with all the aritfact upgrades), would have a system where people could be warned a fair amount ahead of time (it is announced that you have discovered a Titan before you have it repaired), and make the artifacts more relevent (I wouldnt be suprised to see some kind of research that will just 'discover' 1 or 2 artifacts, seeing as how the war has been going on, if theres artifacts all over, you're bound to run into some of them and use them)
