We'll be addressing more specifically what you do and don't know in a subsequent release.
We've quite a bit that isn't in the players' hot little hands but we still need to establish greater consensus among the devs on how it all breaks down.
I wish I could share more of the story today but that would probably result in more confusion and alternate versions to confuse the issue.
I hope soon to illustrate the manner in which THIS settings team has interpreted the legacy of previous settings team incarnations.
In the meant time, all you need to know is it's a freakin crater and it's known as Shindrok's Crater to your characters.
Why it takes 5 pages of debate to establish such a fact is precisely why if it weren't for a few devs and prospects willing to endure the absurdity of certain things on the forum, your cries would fall on deaf ears.
