We haven't gone into any details about the cave. We've been in a different entrance then the one you'll be using, so you can describe it as you want. I am trying to get to a big battle between everybody and the big snake, but there's some details that need worked out still. I've got to go back and edit some of my posts because I've found out they don't fit, then I'm taking the big snake to the campsite. We have a battle, and then...
[edit]
Zhai has pointed out some mistakes I've made and some things that needed clarified, so I've gone back and edited some of my posts. Here's the edits:
The cloaked figure on the Pterosaur flies quickly to the mouth of a cave after having attacked Laragorn.. He takes the book and puts it in his pack along with his glyphs and other treasures. The figure then enters the cave to be greeted by an army of gobbles and his lone henchmen. "Good! All is prepared. Everything has come together even better than I could have planned. It seems that fate is playing into our hands." He laughs wildly then enters the cave. He moves quickly, knowing that time is of the essence. He finds the spot prepared for him and lies down. He pulls out the glyphs prepared especially for this purpose. Then to his henchmen he says, "Once I am unconscious take these and put them in my pack along with the book and give it to my Pterosaur. He knows what to do from there." Then the figure begins to utter something...
As Farren and Spetyco walk back towards the campsite, Spetyco cries out, then falls to the ground uncounscious. At first he appears dead to his companions but he is still breathing and has a pulse; however, he is completely unresponsive to their efforts to revive him...
As the dark figure becomes uncounscious his follower gathers everything in the pack and takes it to the Pterosaur. It then flies off, circling the campsite high enough not to be noticed.
Spetyco finds himself in a dark place. There was a foul stench in his nostrils, but as far as he looked in every direction there was nothing but darkness.
"Hello, Spetyco!" an other-worldly voice calls behind him. Startled he whirls around to see the hooded figure with his face.
"I had hoped we would not meet again. To see my face on someone such as yourself disgusts me," and the vile creature spits onto the ground. "But here you are!"
"Wh... Who are you!" Spetyco demands. Then memories come flooding back. As they do Spetyco stands taller and a grim look comes over his face.
"You! You thought you could get rid of me so easily!"
hopefully that will clear up who the rider was, and so on... Now about the serpent. I thought it was a portrait, but it is actually the body of the snake hanging in the magic shop

. Thank again Zhai for point that out. So I've made the following edit:
Elsewhere, the false Spetyco in a seculded area near the magic shop begins to summon the spirit of the great searpent Zhai who's body hung in the magic shop.
The real Spetyco grows tired but continues to try to contact someone, "Is there anyone out there? Can you hear me?"
and a little later:
As the huge serpent rises from the magic shop the false Spetyco laughs wildly! "No one can stand in my way now!" He climbs onto the serpent and they head towards the campsite. "First we shall take care of those meddlesome 'campers'. Then I'll make all of Yliakum bow to me, or die!"
On the way he sees a lone diablo heading towards the campsite. He considers killing her, just for his own amusement, but decides he must stay focued. "Onward!" he cries.
Let me know if I've made any other such obvious mistakes. I'm new to PS, so I've got alot to learn still.
Hope this helps the story flow better.

Thanks.
