Eventually, I did find a SIK chest. It wasn't far from Candeth. I used every SIK I had, and got . . .
1 scroll I could use.
As in, "I've done better on the nickel slots in Vegas, because at least there some skank will offer to (blank) me while I'm pulling the one-armed bandits, and as creepy as that is, I think I'd rather be (blanked) by a skank instead of opening chest after chest, because at least in Vegas I'd be the one doing the (blanking) instead of getting (blanked)."
So I went to the MP and spent like 20 MMDs on bots buying MOST of the scrolls I need. I still have a few spells I'm looking for, but plenty of time to find them, since I don't want to train creature until I have every spell, and need all the XP I can save for the "don't lose your buff when you die" augment.
Time to sell that War Rare. =/
