Unbelief and Vitriol

[Sherman Landlearner]

I noticed, as I reread LF'sB that SRD uses vitriol for...
-Covenant's anger
-Ur-vile's power
-in 2nd Chron, the mottling of TC's power
-Angry thoughts of both TC and LA

It seems that SRD is actively trying to remind us that we still, technically, don't know the land is real. We assume it is, and that at the end, it'll be proven. But we don't really know. His using the same words for thoughts and a "reality" in the land seems to be trying to remind us that the Land is, potentially, just TC's thoughts turning against him. So how do we really know?
Other than vitriol, can anybody find an example for this?
Or am I totally of my metaphorical rocker and sitting on the barmy carpet?

It is worth saying that vitriol itself is a word suitable for describing both tangible objects and (for our purposes) intangible ideas. The word caustic is also capable of capturing both the physical burning and communicative harshness of the word vitriol (I have no idea if this appears in the chronicles).

The idea that this word is intentionally used at certain times to bring about the precise effect you describe seems doubtful to me at the moment, but I have little to say on the subject myself (except that, in the second chronicles, the presence of both Linden and Thomas in the Land seems to bring into doubt that the Land is entirely imaginary, and that in t he first, Covenant's recovery after the Creator promises said recovery and one doctor referring to it as a miracle seems to resolve that question).

i believe he will leave the Land's reality up to the reader.

Agreed on both counts, both. And caustic does appear in the Chrons. A lot.
