Edit: All those new informations lead to a lot of questions.
I can answer a few of those :3
Whyare the Yor no longer a Collective, and what is the meaning behind calling them Singularity?
They probably achieved a technology singularity in the time since Galactic Civilizations 2. Basically an exponential increase in processing power and technical ability.
Why is it suddenly unknown what the Krynn look like, when it was said in GalCiv 2, that they aren't one singular race, but a religious group, consisting of several races, all originating from the same world? Why was their background changed so much, for that matter? I didn't like those religious zealots that much, but I found their background pretty unique.
They're talking about the baseline Krynn who look like Ynrhed Eidden. You know, really strange eyes and jaw guy?
If Toria is only 20 light-years away from Drengi, then why did it take the Drengin 70,000 years to transport the stargate there? I never understood that part.
Depending on the speed the Drengin were capable of, then it could take anywhere from millions of years to around twenty exactly.
You activated my OCD and got me thinking, so I was forced to do math:
20 Lightyears = 1.892e x 17 Metres
1 year = 31,556,900 Seconds
Time elapsed = 70,000 Years
31,556,900 x 70,000 = 2,208,983,000,000 Seconds
1.892e x 17 /2,208,983,000,000 = 85650.274357 m/s
That sounds fast, but the Drengin aren't exactly hustlin'. I chalk it up to having to carry a stargate the size of a small city with them, but meh.
