As I mentioned, this will include dream-casts, as well as a date of birth, alliance, and general power level (high; above average, fairly high; above average; average; below average; below average, fairly low; low). As far as OCs are concerned, a link will be provided at the top of the chapter where they are first mentioned. The bios have been written as of the beginning of Uncovering the Truth so as not to provide any spoilers.
For ease of navigation, I have split the bios into three sections:
Marauder Era
Hogwarts Era
Next Generation (will be empty for some time, I'm afraid!)
