So...not all of them are errors.
Boggy did have a bottle of what looked like wine to Tom. But don't assume it was human wine made out of grapes. It was a glass wine bottle with a liquid in it.
The main thing he got drunk on was the Denubian Choco-Coffee(TM) and that is served at roughly the boiling point of water.
As for Ramses estate...it's very much air conditioned and climate controlled. The ArchDemons really have no problem with this. Cold Fire is well known. It's basically Anti-Fire, an absence of heat. For high powered demons (including Tom) who can control fire, they can also control anti-fire, that which we call Cold Fire.
{In fact, as they observe in "The Almight Johnson's" (syfy/netflix/New Zealand show about Norse gods) at one point--"Cold burns, very much like fire."}
As I've said before, the ambient temperature in the Courts is about half what it is elsewhere, and if you go inside, it's even cooler in most places.
Here's the thing, humans know that to preserve things, like food, old documents, you have to have some climate control, it seems to me that a demon who lives for thousands of years, would also figure this out after a few attempts and thus compensate.
What I think is happening is you are seeing half empty glasses rather than half full glasses.
If you see stuff, like the piano, you should assume that this is a sign of the owner's power and wealth. They can afford to have and maintain something that shouldn't exist where they are. Therefore, if it exists, and it shouldn't, there must be something going on, say in the background that you aren't aware of.
So case in point from book 2:
Quote:The plateau was about twenty feet in diameter, just sufficiently big that they could all land on it. Tizzy with Talarius, Rupert, Tom and Antefalken the bard. Tom looked over at the bard who was putting his harp away; he had had it out batting away arrows when they had been banished from the city.
“How do you keep the wood from drying out?” Tom suddenly asked. “I’d think this place would be literally ‘Hell’ on it.
The bard smiled mischievously. “It’s Denubian Wormwood. It’s quite at home in these environments. Takes a bit of Denubian worm slime now and then, but that’s it.”
“Same place as the Choco-Coffee?” Rupert asked.
Antefalken shook his head, “You forgot the TM. Denubian Choco-CoffeeTM.” Antefalken corrected. “The Denubians get very picky about their trademarks.”
“Sorry.” Rupert said.
So there you have an answer on wood. Perhaps the piano was made of the same wood, or similar...or as I said maybe he's got really good cooling.
And if fact...it is my belief that this is the case. You will note (as i recall) there are plants and trees on his estate (recall the greek like demons wandering around gardening and doing things). Those don't grow that well here either.
From what I understand, his estate/enclave is sort of a biosphere with better temperatures inside for his gardens and palace.
So in fact, one of the things that should be making an impression is, what Tom would be up against if he were to get on the wrong side of the ArchDemons.
These guys are basically mini-demigods, with large infrastructures and lots of power. Tom's got a dumpy cave.
But the power of the ArchDemons is nothing to the power of the Demon Princes who have carved out the Courts of Chaos, and the power of the Demon Princes is nothing compared to the power of the Gods, who have carved out entire planes of existence.
So my argument would be, don't assume that something that doesn't make sense immediately (like a glass table) is a mistake or an anachronism.
yes, there are some oversights, that's why T-A-G is going to do a beta reader program next time, but a number of these things that don't seem logical are there on purpose. Some of these questionable things may be answered later, some may not, but the ones that are not--well they might be mistakes, but they might also be things left for the reader's imagination. I.e. a puzzle, why/how would this ever work? What could be going on?
