"I am no mere cat." Syvet mentions. "Long ago, before her death, I was the familiar to Yelizaveta, former queen of Irrisen." 

"You're on...the right path. Continue...going...this way." Make a DC20 Sense Motive check.

Jirel would blink at the cat. She kinda, really, wanted to pick it up and pet it. She’d refrain. For now.

(I dunno, cat seems legit)

None of you are able to detect Syvet's internal discomfort, which means that you're all surprised when four tentacles pop out of the stump the cat is sitting on opens up to reveal a maw filled with sharp teeth and four tentacles.

Zaf pops up the hood, finger crossbows the creature, and said, "You're not the only one with a final form. Behold!" With that, the pelt flows over the rest of his being and reshaped all beneath it until a great winter wolf stood in Zaf's place.

Action: Activate Rimepelt's Special Transformation, transforming Zaf into a Zawolfy.

"Bwehh!" Jasun grunts in disgust, watching the creature transform. He waves his arms around, summoning darkness in the form of sharp lances. He turns to Sera, whom he knows the dice gods are fickle with. He unleashed his two bolts and cried out to her.

"Sera, my dear! When you see fit to find an opening and strike, may your blades strike true and the gods be in your favor! You can do eet!"

The blonde would cock her head to the side in slight confusion at the attacking stump. Then with a shrug, she’d hack her way through to the target.

Jirel would growl, lashing out in defence against the tentacles.
