Ok,can someone please explain that fountain to me?  First of all, was 
it bewitched by Dumbledore to help fight, or was it designed ot 
protect the atrium of the ministry or what.  All I know is that all 
of a sudden the foundtain was fighting the Dark Lord!  

Also aboutthe fountain but on a totally different track.  Why is it 
that magicalbreathren are considered wizards, witches, goblins, 
cenotaours and house elves.  We certainly see other things capable of 
magic (the valentines delivering dwarves in COS and the leprechauns 
in GOF just to name a few).  And with the way house-elves are 
treated, I am uncertain why they would have made it in. 

Thoughts?
