I rather think Palp covered all that was to be said about breaking promises in the consequences of all that. As for the money, though agreeably we are a little light on magic items for our respective levels (which is a very simple thing in game play for Umi to take into account when designing encounters), we really don't have much need of the money. Money is money, the scribes are what we are here for (or at least part of it) which makes them much more important. If the MGs keep there end of the bargain, and agreeably that is a rather big if, then I think the money was well spent I say.
Yrisz would be a bit more draconic in her outlook, we promised, then we promised, end of story. She's think all this killing is rather wasteful, regardless of her personal doubts regarding merits that the MGs bring to society as a whole.
Umi, if Polon gets Zephyr even close enough to the door to limit Yrisz exposure to hazardous fire, she will gladly try to stabilize our poor half elf friend. That is of a primary concern.
It would look something like this:
Move Action if needed to be next to Zephyr
Minor: Put down vial so she has her hands free.
Standard: Stabilize Zephyr
* Diplomacy Heal to stabilize the Zephyr *
If not, well things haven't really broken down enough to risk feeding Noxias the vile. Though if they have by Yrisz turn, it would look something like this.
Minor Action: uncork vial
Move: Examine vial making best guess (Does it seem magic potion, salve, or poison)
* Arcana or History Check "What is this gooey stuff" *
Standard: Administer as healing potion unless she knows it to be otherwise, and thus she uses accordingly (unless it proves a weapon poison which she will abstain using).
Free Action: Malk0lm rolls a new character.
I can't wait to hear what the MGs have to say.
Edit: Well that makes up for all the snake eyes I've been rolling in my Monster Hearts game...
