Re: Initial Thread
1)
Think of this more like a recap of the critical events from the last century, like when you were in history class and they talked about a war, but they didn't tell you about every battle of the war, just the ones that are deemed "really important". As such, these are only the most culturally relevant events. I would say the earliest reliable report of a super would probably be mid-1800s. As mentioned in the post, though there aren't 100% certain sources, it's believed that supers have been around basically forever.

There's no clear reason why that humanity knows of, but the alien invasion didn't go for South America initially, and they started getting pushed back before they had a chance. There are probably theories like that, that South America's southern coasts are less populated and were thus less enticing targets, but who can say for sure?

Hey, I'm leaving it vague. You guys don't know about this; the only one who has a chance of knowing about that event at the start of the campaign is probably Kestrel, due to his media background and ties to whistle blowers. Even then, he probably doesn't know or has very limited knowledge of it.
As far as a name goes, I think I would prefer not going by "The Sentinels" since there is an organization that already goes by that name. Even if it's supposed to be dead, you can never account for time shenanigans, right? Then it'd get real confusing that you both share a name.
