Fracas!
Rallyn bellows out into the sudden darkness, a call to arms, trying to alert his fellow students.
(I'm acting under certain assumptions about what your characters do. I should've called for actions and initiatives -- it's contrary to the normal 3e way, but makes posting a lot faster. In the future I should be doing both. If the battle situation should change, you'll be able to change your plans quite readily.)
Initiative:
Keith 21
Kith 17
Arana 17
Maerath 16
Charlotte 11
Ellie 8
Rallyn 7
A loud voice calls out from the glimmering, moving darkness. "Where are you, Yodwin? Bring me my book, you old fool." The voice is husky, clearly male, strained as if in pain or barely controlled rage.
Keith brandishes his rapier, prepared to defend himself. With his low-light vision, he sees the rushing form --not coming from the same direction as the voice -- rush up to him and attack him with claws extended. It's gender is unrecognizeable, but it's clearly humanoid shaped. Solid black, like oil gelled into a man's form, but somewhere in size between a gnome and a human.
Keith whips the rapier forward in a clean thrust, too high for a killing blow, but grazes it near the shoulder.
It claws madly at him, but fails to connect with a brief flurry after its leaping rush.
Kith slowly and stealthily makes back to where the he believes the rest of the group are congregated. Your low-light vision allows you to see color clearly and from your position on the top of the stacks you see a number of oil-black small humanoids rush forward toward the sounds of a scuffle.
Arana hears the gravel-voiced stranger speaking from somewhere in the back of the library, deeper into it's recesses, more toward the private chambers of Yodwin, possibly even going up the stairs at the back of the scriptorium's open area.
Your dancing lights cantrip flashes a bright flare of light for a split second, then is extinguised by some sort of magic. Your eyes are dazed by the flash, but only for a moment.
Maerath quickly covers himself in a spell-woven cloak of invisibility. A small oily humanoid rushes buy, sniffs the air briefly. You hold very still... and it passes you by. Squeekie is also covered by your spell, and they don't seem to see him either.
Charlotte, seeing Keith under attack, adds her blow to his. Your strike is calm, precise, and should be a killing blow, but the monstrous creature merely shudders briefly and keeps clawing at Keith.
A second one leaps upon the same table you and Keith are using as a refuge and claws at your leg. You nimbly step aside and it merely grazes you.
(OOC 3 points)
Ellie Caught flatfooted by the turn of events, you reel in pain when a talon rakes down your back, you attempt to defensively manifest a weapon to your hand in response to this action, but surprised by the monster and unable to see, you're not sure where to or where it would be safe to do so.
(OOC 7 points, failed defensive manifest roll. If you wanted to take a different action, let me know)
Rallyn races in a burst of speed to where he believes his fellow students are. Two oily creatures move to bar his path, and he slides along the tiled floor to a stop. Both of them swing at you, only one manages to connect a glancing blow along the unarmored back of your hand.
(OOC 2 points; they had readied actions)
You stamp your feet on the ground and a psychic shockwave. One of them falls down; the other nimbly retains it's "feet" and looks like it's about to claw at you again.
