the unicorns that they were looking for in the first book during detention?

Is it A werewolf/lupin
-in the moon, bright
- they come out at night

:S argh

Hmm....there are some good guesses here. I'm almost wondering if it's centaurs, since they burn sage and something else I forget when they're practicing their augury (not the bird, but another name for divination/foretelling the future).

Riddle:

Creatures, creatures, burning bright
in the forest of the night.
HINT: Take "Creatures" as the literal meaning. Actual beings.

Centaurs? beat me to it

how about Thestrals?

Correct The "burning bright" bit was referencing to their silvery glow, or however it's but in the novel.

New Riddle:

Two thirds of a hat,
Throw it away,
Put a G in the middle,
Now what does it day?

hag????

Hag...

Hagrid

Ha the first two letters of hat, g in the middle because there's two letters on each side and rid because you threw it away

Yay, someone got one of my weird cryptic ones!

WELL DONE JENN!

New Riddle:

I'm one letter less than a dog,
Some might think I'm a bee,
I'm little and annoying,
But you know you all love me.

New Riddle:

There, out in the darkness,
a fugitive running,
fallen from grace,
I never shall yield,
'Til we are face to face.
He knows his way through the dark,
But mine is the way of the Lord,
Those who follow the path of the righteous
Shall have their reward.

Nagini?

Bellatrix?

Hmm. Wormtail?

Very much on the right lines ma dear

Good thought, but incorrect

Same to you, Foxie. It's not actually a direct follower of Voldemort, more of an ally.

Keep trying!

Hmmm. Greyback?

..darn. my guess was Greyback as well.

Lucius?
cuz it says fallen from grace...
