Sirius the star
I don't know if this info has been posted before or not but innywho...
From the bookPatterns In The Sky by W. Maxwell Reed:
" Canis Major, the Great Dog, is a small costellation but an important one. It contains the brightest star in the sky, Sirius,..."
Could this be where JKR got the name and the animal form which he takes in the books? Or maybe something more?
my theory regarding sirius voldemort and the veil
You know that voldemort did many research about the after life and how to be immortal....
to avoid death he succeeded, he had been saved from the reflected curse that was sent towards harry... (Im not that good English speaker sorry)
I think that voldemort in his research found out the way to avoid getting into the vail or to be sent to it.
He was less than a ghost (some kind of soul maybe?) he moved in the shape and way he was suppose to be in the vail...but he was outside it
voldemort must know the veil secrets like how to get out...4 which purpuse it was made....how to avoid get into it....etc
(relation to the dementors they are connected somehow to the veil for 100%)
probably he will try to set a trap 4 harry by telling him he's the only one that knows the secret of the veil and how to save sirius....
maybe the wispers behind the veil are the people that traped in the wand when cursing the killing curse, they cry 4 help or something
because of that the aveda kadebra counted as the most evil way to die
because u r not really a dead till the man who cast it die or the wand snap
we know that voldemort reseach the immortality way
I think he was unspeakble because:
1)he got good relation with alot of DE in the minestry (aka melfoy etc)
2)he got top grades in his time.
3)the best way to get all the resources without getting any suspicious is to work as unspeakable that got good privilege and access to the veil
that is my original theory all rights reserved
