Well over the past few days I've had alot of time on my hands so I spent some of it looking up Harry Potter web sites. I mentioned in the Playing thread that I'd post some of them here.
The Harry Potter Lexicon
Really this is almost the only site you need. It might take a bit to find some stuff, but that's only because so much is there. Really, the few other decent sites I've found are just somewhat easier to use, but not as thorough copies of what's here. The Lexicon has Maps of most of the main locations, a complete index of spells and magic items, as well as characters. It's got a timeline of Hogwart's history (so we'll know who from the books should be there when we are). It even has essays theorizing why Muggle technology isn't used at Hogwart's. (The gist of it- magic use draws in lots of power which shorts out complex electronics.) All told, this is the best reference I've found.
MuggleNet.com
This is full of all kinds of info about the books, the movies and everything. What probably interests us is just past mid-way down on the links on the left- the "Info" section. Like I said, most of what's there is at the Lexicon site, but it's presented here in a somewhat "cleaner" way.
Wizard Money Converter
Ok, this may be a somewhat silly link but it may actually come in handy, especially for figuring how much magic items might cost or mundane equipment. At the very least it can keep such discussions "in character".
Harry Potter's World of Magic
Ok, this one's a little weird, since it's presented as an imaginary amusement park based on Harry Potter, but, it does have some useful info.
1) Since the "park" is divided into areas named after the various books, the places in these areas are described.
2) A possible map of Hogwart's? Yes the real Hogwart's is impossible to map with the moving stairs and rooms, but the
Marauder's Map from the middle of the page could be used as a general reference, if we wanted.
3) A
Sorting Hat quiz. We could answer the questions in character as one method of being sorted. (Assuming that's not already pre-determined by the story needs, which would work fine as well)
Well that's all for now. Hope you guys find some use in these.
