i think dat the first half of de book will be about finding and destroying the remaining horcruxes whilst the final half will be the second war. the last chapter of "the order of the phoenix" is called 'the second war begins' and i think the last chapter of this book will be called 'the second war ends' and we know that this chapter is to tell us all about the survivors and what happens to them. A few years back, JK admitted that the last word will be scar although it might change in future edits. There are many possibilites i have for this speculation:
- harry kills voldermort and lives but the scar dissapears as every part of voldermort is now gone and that is what connects harry with voldermort
- harry dies and becomes a ghost but the ghost version has no scar
- someone else sacrifices themselve for another person (e.g ron for hermione lol) and create the boundary of love which might mean that somebody else will survive an avada kedavre curse
the war is bound to be big and will involve all the different races such as giants, werewolves, dementors etc! i think the characters of the D.A will help fight aswell as only a few have had their chance and otherwise it would be pointless if JK rowling put these characters and the progress into the DA and not intend to use them. Irony will occur consistently throughout the war i think such as:
- lupin will kill fenrir greyback
- arthur weasley will take out lucius malfoy if he manages to escape azkaban
- neville will play a part in the demise of bellatrix and i also reckon he will become a herbology teacher as sprout either dies or retires and he develops a plant to help revive hios parents to full health
- harry will take on malfoy for one last time
- ron will enjoy takin on crabbe and goyle if they follow in their fathers footsteps join the ranks of voldemort
- hermione will take revenge on dolohov for dat wierd spell that caused her some damage in "order of the phoenix". dolohov murdered the prewetts who were the brothers of molly weasley which makes dem the uncles of ron and ginny etc.
- hagrid will like to have revenge on macnair for 1)trying to kill buckbeak and 2) persuading the giants to join voldemort
- harry will fight snape and take out all the evil hes ever had for him and unleash it against him
- the order of the phoenix will have deaths just like the older order did. i have a feeling tonks will go but only after lupin declares his love for her
- most of the death eaters will die whilst some might be sent to a new prison???
- many muggles will die
other vital parts of book seven that could have affects:
- krum will return: why? maybe to help fight in the war and bring magical co-operation back into the magic world. or maybe hermione dies and hes at her funeral??????????
- sirius's motorbike and mirror have part: the last we heard of the motorbike was when hagrid used it to take harry to the dursleys - did he return it to sirius????has hagrid got it somewhere??? harry smashed the mirror sirius gave him but im sure with a bit of magic it can be repaired (reparo?) but sirius IS dead so he will use the mirror to communicate with someone else then
-kreacher plays some part: he is in harrys command now so maybe harry can use him???or will kreacher betray someone else to their deaths???
-jk rowling refused to comment if the locked door in the department of mysteries will be in book seven. dumbledore mentions this room to harry in "order of the phoenix" when he is telling him about the prophecy. dumbledore mentions it contains powerful magic
-some non-magic folk will do magic but its not petunia: when jk rowling said this she did not say the word muggle which means it might be a squib - filch??figg??. either way it plays an important part - i have an assumption its dudley. dont no why but always felt theres more that meets the eye bout him and we might be able to work it out when we discover what he felt when the dementors were near him
-when harry relives the graveyard events to dumbledore there apparently is a 'gleam of triumph' in dumbledores eyes when harry tells him that voldemort used harrys own blood for the reviving potion. we find out why he was happy bout dis in book seven from someone but i dont think it will be dumbledores portrait - i tink voldemort will tell harry stuff dumbledore never
-rowling states that a member of the order of the phoenix who has not had such a big role yet will have one in the final book. rumours are that it will be aberforth dumbledore who will avenge the death of his brother. i think it will be dedalus diggle. he was mentioned in "philosphers stone" and was one of the advance guard in "order of the phoenix"
- rowling also states that ravenclaw will have their day: there has only be one main character from ravenclaw that has been mentioned and thats cho chang. she will be up for fighting voldemort as she suffered the loss of loved one cedric diggory but also of her feelings to harry. she is the only main contender although other ravenclaws mentioned are terry boot, michael corner, roger davies etc. some are members of the D.A
as for horcruxes:
only two are confirmed - marvolo gaunts ring and tom riddles diary
this leaves five left:
possibilities:
- salazar slytherins missing locket: believed to be stolen from hepzibah smith by tom riddle. this is what dumbledore and harry expected to find in the cave. There was a locket mentioned in "order of the phoenix" when they are clearing out a cupboard in number 12 grimmauld place that none of them could open. if R.A.B is regulas black then when he stole it he could have put it in the house knowing that the house can not be seen let alone entered without the parchment permitting them to it. nevertheless when voldemort heard of this betrayal other death eaters were relatives of blacks such as bellatrix and she could of got voldemort permission to go inside.
- a hufflepuff cup engrave with the badge also stolen from hepzibah smith by tom riddle. its wereabouts is unknown yet there is a hufflepuff member in harrys year that goes by the surname of smith which is ofcourse the obnoxious zacharias smith. he could be a relative of hepzibah and have the cup in his famils possesion although 'smith' is a popular surname so it could be anywhere
- an unknown item belonging to godric gryffindor or rowena ravenclaw yeh the only two relics of gryffindor that are known about are the sword and the sorting hat which both reside in dumbledores office. jk rowling has confirmed the sorting hat is not a horcrux. no ravenclaw relic has ever been mentioned but rowling insists ravenclaw will have their day in the end. maybe they will destroy this relic???
- the final possibilitie that has some mention in the books is the great serpent nagini: is known to be risky to entrust part of your soul into another living thing yet volemort is reckless and will not be afraid. nagini has lived longer than any other average snake which might be because she has part soul of a human inside her. another correlation is that harry is only connected with voldemort so see's what he see's and feels what he feels. yet in "order of the phoenix" harry sees through the eyes of the snake we believe to be nagini. now this is impossible unless there is a part of voldemort in the snake althought dumbledore said that voldemort had possessed the snake for that night but nevertheless this is before dumbledore knew about the horcruxes.
sorry its longwinded - had to get it out of me!! i got my sources of information from
http://en.wikipedia.org/wiki/Harry_Potter_book_seven and then clicked on other links such as 'horcrux' and 'r.a.b' and it gives you all the information and their sources
