BRIEFING:
Albus Dumbledore has been attacked by a herd of Dementors and Death Eaters. He has left you four items: a Time Turner, a bottle of Polyjuice Potion, a long, silver hair and a note. The note says:
'Mr. Harry Potter,
I have been kissed by a bunch of Dementors and hexed by a group of Death Eaters. Professor Trelawney gave an accurate prediction for once and warned me what was going to happen, so I decided to think ahead and leave you these objects. Put my hair into the Potion, kindly brewed by Professor Snape months ago for safekeeping. Drink it all; it should last you a while. Then use the Time Turner to go back and head the Dementors or Death Eaters off by clicking on any Mission you would like to take. Good luck; two turns should do the trick.
Yours,
Professor Albus Dumbledore
PS: I've heard Mr. Fred and George Weasley have sent you a... gift. Go to the Gryffindor Common Room, an owl should be waiting for you there! However... I believe I've fogotton the password! You'd better go and find out what it is.'
Click on the Mission you would like to complete for Dumbledore on the left. And, Potter, don't land yourself in the same fate Dumbledore did, there's a good chap.
