Great post, Alshain! I'd be "entertained" (enlightened) if you'd do
one for Bellatrix (woman warrior?), which of course you know is a
bright star in the constellation Orion. (I'll bet Bella's Patronus 
is an Amazon.)
 
Mandy here:
I have the idea that all petronus' are in animal form, something like 
the American Indian Animal Spirit Guides.  

If that is so, Bellatrix's patronus cannot be an Amazon who were a 
race of human female warriors.  Bellatrix's petronus would be a 
Hyena. 

Hyena's are truly fierce predators and scavangers who live in 
matriarchal societies where the males are significantly smaller than 
the females.  They also laugh or scream in place of a roar.  Sounds 
like Bella to me.

Carol again:
Interesting idea, Mandy, but I don't think we have enough information
about patronuses (patroni?) to assume that they're necessarily
animals. An animagus form would have to be that of an animal (by
definition), but if boggarts can be inanimate objects (a moon or a
crystal ball, depending on what we think of Lupin's boggart) or people
(Snape, dead family members), why couldn't a patronus also take human
form? Bellatrix (woman warrior) suggests an Amazon patronus
(protector) to me, just as Sirius suggests a dog animagus and Remus
Lupin suggests a connection with wolves.

I'm not saying that I'm right, only that we've seen too few patronuses
to know what form they generally take, or if there's a general form at
all.
