About a million years ago, Ben Bryddia asked some questions and it is high time I say - HIGH TIME! - that they were answered. I shall reproduce much of his comment enclosing said enquiries here for context.
"Do you have an index for all those notebooks? If so, how is it set up? Yeah, it's a strange question, but I'm curious what form of note organization you've found most helpful..."
Ooh how I wish I indexed my notebooks, bit they are merely a repository for collecting thoughts as they come to me. 36 notebooks in I am starting to find it difficult to find older ideas, though it can be an adventure to go hunting for some half remembered notion I KNOW I wrote back in NB 32 or was it NB 31...? It can also drive me a little nuts trawling through every page when I just want to get on with what I am currently focused on.
I am very much a scatty-headed creative type, and though there is a quite complex system of symbols to show what each note is, there is no indexing; so I have no help for you there, Ben, sorry.
[SPOILERY BIT AHEAD]
"I was rereading the conversation with the Lapinduce in Book 3. Out of curiosity, if land monsters are birthed from threwdish muck, where do all the river and sea critters come from? Is there such a thing as threwdish waters or threwdish ocean muck?I'm assuming that the false gods are to nadderers what urchins are to nickers and bogles. Is this correct? I seem to recall that Kraulschwimmen and false gods aren't on the best of terms."
Kraulschwimmen and false-gods are on very bad terms. Indeed, it is the kraulschwimmen who have been set watch over the mad false-gods - the pseudobaths - to make sure they never rise again as they did in the beforetimes in the folly of their arrogance. The false-gods were once like the urchins but sacrificed their place for the sake of seizing more power and so were thrown down and made idiot, the drool and seethe in the crushing black of the lowest oceans, whilst kraulschwimmen keep watch and wrestle with them when e'er an everyman seeks to call a false-gad back.
With the oceans, the deeper down you go the more threwdish they become, and the water deeps are fairly throbbing with threwd, and as you surmise, their muds are fertile places indeed for spawning new monstrous life. River nickers and other fluvial critters are either sprung from the sludge of waterways bubbling up in strongly threwdish lands, or from the slimy beds of shorelines that runs past threwdish places. Of course this is not the only way monsters come to be...
I hope that suffices.
