1) Tom getting bigger? We sort of assume Rupert will. Hmm, hadn't thought of that, he could end up being 18 or 20 feet tall! Not sure though if the first conjuring fixed his height or not. Good question.
2) I think a lot of people are going to assume he is bigger than a 4. A lot of people are going to want to know the secret of what he did. That's almost as useful as Lenamare's book.
3) You really are brilliant! Can't argue with that. Of course, I can't tell anyone what I know about the Concordenax, I have a great line on that topic, but I won't get to say it until at least book III.

Hmmmm

I am old, and I can testify as to luck. Helps a lot.

I can't tell you the name of the oldest demon in the book as she would certainly cook my privates over a hydrogen flame...let's just say, she had this epic romance and then break up when her husband cheated on her with this '(rib) bone headed' other woman.

The demon princes(es) are clearly the oldest demons, and generally power and age go together.

if you look at the timeline, you can see Exador is probably a few thousand at least. Ramses is over a thousand as well, and he didn't just pop up that way....

This Bess person I've never met, so no idea how old she is.

Boggy is some 400+ years...he says exactly (or at least how long he's been a demon)

Antefalken is a lot older than he looks. Check out the timeline for some ideas...plus Antefalken's Reack on the map is named after him...really long, really old story...

Otherwise, I sort of have trouble remembering. I don't think anyone is over a billion years old though...vast majority are several hundred to several thousand

Cthulu is really old, but I think he's technically a god, as are his poker buddies, like that guy who gets really pissed when you mention his name, no, not that piss ant snake nosed Voldemort...who isn't even a demon...just a necromancer...and not THE NECROMANCER (the one that had the rings made) who I have mentioned before...he's really old too...but again...not sure if he counts as a demon...

The fact that so many people want it is useful in itself. The value of an object is determined by the people. Water is really cheap next to a f.w. lake, but priceless in a desert.

Apparently a lot of people who know what this book is, or think they do, think it is useful.

the problem is, they just don't know how to open it. They haven't been able to hack the lock on it. Of course, even if they get it opened, it will probably be encrypted text etc.

Not entirely useless, several powerful people really want it. Still a bit surprised Tom just gave it away. I always get very suspicious when powerful people who don't care one bit about others start fighting over something. My first instinct is to try and destroy it... than again, I might have travelled too much in worlds like Greyhawk, Toril and Cerilia.

Wanting something doesn't make that object useful.

Well, at least in this book, Lenamare's book is essentially a macguffin, a plot device. It do no other purpose than to drive plot. It might be of more use in latter installments but not here.

Except maybe for phone books...they have great casts, lots of characters, but not a lot of plot....

You mean like the Holy Grail, it doesn't actually do much except send knights on quests, starts wars, sacks cities, etc.

Seems like a really powerful Artifact of Evil if you ask me. Remind me not to drink from it, even though it was filled with blood at one point, so would otherwise be tasty.

I don't remember the movie you speak of, I don't get to see too many movies, I don't get to Earth very often.

However, I was on the one plane of existence ran by robots, who needed my assistance in ridding themselves of these human vermin, so I helped them program these time traveling killer robots that coincidentally, they called Terminators.

JUST became conceited?

Why thank you, most people assume I was just born conceited. It's been a long journey and struggle to get my ego to its current heights!

Ah, but what if my "craziness" is just an act?

What if I am completely sane and pretending to be insane and nonsensical to lull everyone into a trap!

No one thinks the crazy guy did it! Crazy guys are always harmless and cuddly, you know like Jason Voorhees and Freddy Krueger!

Two of the sweetest, most playful people I've ever met, and they are also batshit crazy!
