Are we gonna describe how we were captured in the first post or are we already in the mansion at that point?

It's up to the person writing. If they want to include how they were taken then they can but otherwise we should all be waking up in the basement by the end of our first post. 
I personally am going to include a bit of how she got there but it's mostly going to be the confusion and panic of what's going on when she realizes she's in a basement with people/ things she's never met before.
