Sector 3: Full Moon, Forbidden Forest

When the friends met in their animagus- and other- forms, it was about
10 o'clock at night with the full moon over head. They followed Remus into
the forest, as he had somehow gotten control of the werewolf body and knew
exactly where they were going. Sirius followed closely behind, making sure
that Remus didn't go berserk or something like that.
Remus occasionally glanced back at Sirius for directions, until
Sirius decided to take over leading completely. After a couple hours of
wandering,the came to a clearing that was surrounded completely by webs,
glinting slivery in the moonlight. Remus automatically backed away from
them, as though they were something poisonous, which, for a werewolf,
is closer than for most of us. Then, the clicking started. It was soft
at first, then it began to get louder and the pace began to pick up...
soon, there was a small thunder of clicks coming from the surrounding
trees. The four, all extremely nervous, backed against one another, looking
for what was causing the clicks. Having done the research, only Sirius
and Remus knew what it was- a veritable army of acromantulas had surrounded
them and was preparing for an animagus/werewolf feast!
That was when one spoke. A soft, shivery, creaky voice that you
would expect to belong to an old rotten house, that sent chills up and
down your spine like small electric shocks. "Our feast has arrives." Then
the clicking stopped. A quiet hissing sound replaced it, the volume undulating
like a snake sliding along the ground "sssSSSssssSSSSSsssss..." as it watched
for its prey.
The eyes came into view. Thousands of tiny, blood red, beady eyes stared
greedily at the four friends. A single spider stepped into the clearing
he was obviously very old, ancient infact, with his giant, smooth black body
covered in light grey hairs that shone in the moonlight. His giant pincers
opened and closed rapidly and small, slim strings of saliva broke and reformed
in the process.
'He,' Sirius decided, actually taking the situation seriously,
'must be the head of the clan of them.'
His question was answered when the giant creature spoke. This could
not have been the same creature that spoke earlier. It had a thin, raspy
voice with a whisper of an ancient story teller, yet there was a command about
it, yes, this was the leader of the clan.
"I,"It said wispily,"am the ruler of the-" none of them could
make out this word"-clan of acromantulas. We all are aware that you are
MOSTLY human,"he stared briefly at Remus before continuing," We also have
guessed that you will not willingly change back to your origional forms,
as that would be stupid. You however are surrounded and when the moon sets,
we will take your friend. You will then change to human and I will tell you
why I have told you so much of what we shall do."
Three of the four friends were deeply puzzled by this, Remus of course,
being a werewolf, had no idea what had just happened due to a temporary lapse.
As they stood there, they realized that the night was waning and Remus would
soon be without protection against the spiders. It was- James realized first
and the others soon followed- a no win situation. If they changed back to human
to reason with their captors, they could get bitten by Remus, or eaten
by the spiders. If Remus changed back first, they would have to change,
or let him get eaten. Lily began to hope they had a strong distaste for
werewolf.
While they stood there in the moonlight, Remus the werewolf shifting
uneasily while the others stood uncomfortably as if the slightest movement
would send the gigantic spiders on them.
That was when it happened. A zip of glittering light passed them by.
A group of centuars had come to the rescue! Arrows flying, they shouted for
the spiders to retreat. The giants stood their ground until one was hit in
the leg and all of it's eight legs disolved. Then, with a panicked scurry,
they all ran into the trees. The centuars took one look at whom the had rescued
then did a double take on Remus, bowed quickly and bounded off into the trees.
The four friends stood in silence for a minute before running back
to the light and safety of the school grounds. Remus began groaning and slowly
his fur receded and he took his human shape once more.
"What happened?" he asked his friends as they popped back to their
own forms, "What did I miss?" Upon hearing this, James and Lily burst out- somehow- laughing,
while Sirius clapped a very puzzled Remus on the back and said,"Why nothing!
We were only just almost eaten by the models we were gonna bring back, and
then save by a bunch of half horses who took one look at you and didn't even say
hello!" Lily and James were now almost doubled up with laughter at the bewildered look
on Remus' face and Sirius acting out what happened, playing all the parts himself
and using a wandless spell to change his voice for the different parts.
