No worries, mate. We're different enough from the series to where you can just know the basics of the races you can function perfectly well. No canon stuff (outside given racial abilities/spells) to clog the pipes.
Anyway, welcome.~ If you need any help, or have specific questions about something, feel free to PM me or any of the staff. We're always happy to help, and there's almost always one of us lurking online to process stuff.
