Hunter, seeing that the group is always sheepish about such occasions, moves up, busts the door open for surprise and fires quickly if he sees an enemy.
Ardo watches Hunter run up to an invisible door and boot it open. After that Ardo follows Hunter into the room with the invisible door barely hanging. "That was a mighty kick Hunter."
Davik holds up his hand up to stop the party, and moves stealthily down the side passageway to have a closer look at the room beyond (I'm assuming we can't see into the room). Once he sees what's in the room, and if there's any dangers to the party, he will return to the party, and report what he found.
Despite Davik's offer to scout ahead, Hunter runs up into the room and finds a room that is filled with more books than you've seen in any one place in your whole life before. There must be several hundred of them! Scrolls line the shelves, all apparently neatly catalogued by some system. Twelve polished skulls, each belonging to a different species, stand atop the twelve tall, narrow bookcases that line the walls. A large table dominates the center of the room, its beautiful inlay work almost obscured by the papers scattered across its surface. A young woman of perhaps fourteen in a short black dress is working at the table by the light of a single candle, copying something out of a great black folio onto a sheet of parchment with a rather ratty looking quill pen; she looks up as you enter and says "Well, it's about time!"
In his fervor to attack the first thing that he sees and not immediately being able to tell if this girl is an enemy or not, Hunter lets fly an arrow. As it happens, Hunter is a little off balance from trying to kick a door that doesn't exist (Possibly to make his entrance that much more dramatic?) and his arrow embeds itself in the side of the table that the girl is working at.
The girl's eyes go wide as she shouts, "What the hell?!?"
"Hi, we are here to smite evil wizards and destroy foul undead. I see you are alive so that rules you out of being an undead, are you perhaps an evil wizard needing smiting? Also why is it about time?" Ardo looks over at Hunter when he is done saying that and then looks back at the girl and says "Arpad?"
"What a great first impression, eh Hunter?" asked Davik as he entered the room behind him.
Out of Character: Do I recognise the girl at all? If not, I look around the books in the room to see if there's any in Common, that look like they might be valuable, or useful to the party. If he doesn't recognise the girl, this is what he does, leaving the rest of the party to interact with her.
"Yes", the girl responds to Ardo, "I'm Arpad. It's about time somebody came to rescue me. I've been forced to be come Tarlech's apprentice for the last six months. Now let's go. I don't want to be here another minute!"
As Davik inspects the books on the shelves, he discovers that it's a great library devoted to the study of magic. There are no spell books, but each section is devoted to a specific type of magic with extra bookcases devoted to the school of necromancy.
Proceeding counterclockwise from the entrance, the bookcases are: I. Universal Magic (A halfling skull); Il. Abjuration (The skull here is large and beastly, but nothing that any of you recognize); Ill. Alteration (A dwarf skull); IV. Charm & Enchantment (An elf skull); V. Conjuration & Summoning (A goblin skull); VI. Divination (A kobold skull); VII. Illusion (A gnome skull); VI. Invocation & Evocation (An orc skull); IX—XI. Necromancy (Three shelves, with a human skull atop the midmost bookcase); and XII. Clerical Magic (A massive bugbear skull; these shelves are mostly devoted to prayers and stories concerning Wee Jas, goddess of death and magic but also contain material on Erishkigal and Nergal and many legends regarding the grim reaper).
"Before we flee Arpad is the mage that captured you still here or is he gone? I do not envision leaving an enemy alive behind me to chase me down."
