Eminiss told us, when he was born. And in the game there is 2001-2002. So he is 37-38 years old.
We killed Red, when he was 36 years old.
And Philip is about 27 years old. In the last note in Overture, we can notice that Howard (Philip's dad) was there about 1970. That means (for me) that he leaved his family in that year.
But there's no way to find out how old was Eloff Carpenter, Amabel and Howard. (Clarence doesn't exist
)
You can ask more quiestons about the game, there are chance I can answer them.
