"...considerate enough to teleport into our rooms in the middle of the night without so much as a "by your leave."" The halfling flings the dagger he was balancing, embedding it into the back of the wooden chair the woman had just been sitting in. That she might have just turned invisible and could still be sitting there observing them had crossed his mind, and well...that was one way to find out...
"Ah! Golharath! So good of you to wake up and join us. I see the early hour hasn't faltered the rituals of your morning ablutions."
Turning towards the others, "Well! I'm all packed and ready...Winterhaven is it?" He nuzzles his pet familiar with his index finger and it croos a bit.
The halfling flicks his dagger, which hits the wood of the chair Elmira was sitting in without any sign of injuring any invisible loungers. You notice him moving his lips and gesturing, but it's very difficult to hear him. In fact, he seems compelled to perform all of his actions as silently as possible for the foreseeable future. Those who hit the proper Spellcraft check know that he is under the effects of Suggestion.
[spoiler]
Thistledown still says the above words, but he inadvertently whispers the words very quietly. If you want to bother rolling listen checks, the DC is double the normal DC for whispering right now, and there's little to no advantage to hearing what he just said. Any further dialogue from him can be heard with a Listen DC of 15 +1/ten feet of distance between you, until the spell wears off, as he will try harder to make himself heard despite still trying to be quiet.
Thistle's character must do everything as quietly as possible for the next 12 hours. He's not being prevented from doing anything, so long as it can be done quietly. Though, I assume he'll be as loud as possible as soon as he make your save.
I'll even allow you to make a new set of saves while you're on the road. As soon as your group sets off I'll let you know how many saves to roll. Success means you shake the spell effect off and are no longer affected.
Now, I won't say that I'm not trying to single you out or anything. This was quite clearly retaliation for your actions, a not-so-subtle initiation of Karma saying, "Hey, watch it buddy."
However, I'm not trying to railroad you guys, and I'm not doing it to be mean, I'm 1) Trying to make things more interesting, 2) Trying to teach you that even though you guys are the heroes, there are consequences for your actions. A couple of the PCs in the other group have already managed to identify Elmira as a particular sort of spellcaster, and she was always meant to be as such (consequently, if you want to roll Knowledge: Arcana, along with a Sense Motive roll, I'll let you guys try to identify her base class as well. The DCs are 15 for Arcana and 20 for Sense Motive). She was also always meant to be abrupt and relatively short-tempered (oh-so-common traits of the tragically sneaky). So the consequences of annoying someone with the means to bite back are that you will get bitten, so to speak.
You didn't think that you guys were the only ones who get to have fun, did you?
